Throughout history, recycling has been around in one guise or another. Even as long ago as 400 BC signs of earlier recycling are known to have taken place. Archaeological reports show that historical waste dumps contained less of what is known nowadays as household waste, such as pots, tools and ash, which demonstrates that people were, even back then, keen to reuse products at a time when natural resources were not so freely available.

Indeed it could be argued that the old ‘rag-and-bone’ man was just an early recycler collecting unwanted goods on his horse and cart, before reusing or turning the collected items into something new. The 60’s TV series, Steptoe and Son, brought this very much to the public eye and greater attention.

During periods such as the World War Years, recycling and re-use were necessary as natural resources became much more difficult to come by. As well as food being rationed, certain materials such as metal and fibre were largely allowed only for use by the government in support of military operations, to meet manufacturing requirements often in the production of weaponry. There was a desperate need to support the military.

Due to rising energy costs, the need to recycle aluminium increased in the seventies.. As a material aluminium uses much less energy in the production process than some other materials. Also it was much sought after because of its non rusting properties. The demand for aluminium saw the rise of scrap metal dealers who were willing to pay money in exchange for good quality metal. Also, in the seventies in parts of the United States of America, the first vehicles were seen to be collecting waste with a separate trailer for the collection of recyclable materials being towed behind the vehicle. This was mainly large bulky items such as bedsteads and old carpets.

To the late 1980’s, early 1990’s and as the importance of managing the global environmental state increased amongst worldwide governments, the focus upon recycling really started to gather momentum. In the UK, the government imposed recycling targets upon Local Authorities and with the introduction of the new legislation upon the waste industry, recycling schemes really began to take off. The once commonly knownwaste disposal companies, began to call themselves waste management companies and demonstrated through the offer of waste collection and recyclable material collection that waste needed to be handled more effectively. Local skip companies needed to become better at what they did.

Today, many hundreds of materials and products can be recycled, ranging from paper, card, glass and plastics, to mobile phones, electrical items, printer cartridges, textiles, clothing and concrete.

What is Recycling?

The term recycling describes the process of reprocessing used materials into new or nearly new products to avoid the need for potentially useful materials or products to be discarded.

Recycling plays a key role in a world where climate change is high on the environmental agenda. It helps to reduce the need to unnecessarily send waste materials and products to landfill or other waste disposal options. This in turn diminishes the need or the reliance upon consuming fresh or new raw materials, reduces energy use and air and water pollution, all of which contribute to lower greenhouse gas emissions.

Recycling is probably mostnoticeable through the recycling services now provided by local authorities for domestic refuse and recycling collections and by modern waste management companies who generally offer a full range of waste and recycling collection services.

To assist preserve the environment a raft of regulation exists, our website gives you the information you need to lead you in order that your requirements are handled in accordance with the law.

In the waste sector, the common promotional activity surrounds the waste hierarchy - ‘reduce, reuse, recycle and recover’. This four R slogan is a simple message designed for a far reaching audience. Think about how you can reduce your waste. Can the waste products or materials be reused? Can the waste product or material be recycled or recovered?

The waste hierarchy is a strategy which many waste management companies and local authorities consider when developing new waste management strategies. The strategy is intended to focus the mind around preventing waste being generated in the first place. Consider the options for reuse and recycling but ultimately minimise the amount of waste produced at the end of the cycle.

So the emphasis is very much on the entire production process. The waste hierarchy extends much wider than to waste management companies and local authorities. Working groups have been set up to bring many sectors together to consider the entire waste cycle. For example, the manufacturer of a product needs to consider how the product is to be manufactured. Can parts be used which can later be recycled or reused? Can the amount of packaging which surrounds the product be reduced? When the product reaches the retailer, is it necessary for the product to be placed within an outer package? Once the retailer sells the product, what will the buyer do with the unwanted elements of the purchase, i.e. the packaging? How will the packaging be collected and where will it go? Will it return to a recycling plant, for onward shipment to a reprocessing plant, where the cycle begins all over again?

How are Materials Collected for Recycling?

Legislation now dictates that all waste should be treated to avoid the amount of recyclables and unnecessary waste going direct to landfill. Since 1996, UK government has applied a landfill levy on all waste disposed of within landfill. The rate of tax has increased considerably in recent years rising from the original level of £8 per ton, to today’s rate of £40 per ton. The UK government has previously announced that this will increase further to £48 per ton by the end of 2010/11. This rate applies to all general waste streams, although there is a lower rate for inert materials. Sending waste directly to landfill is an expensive option and finding suitable methods to divert waste away from landfill is now a priority. For inert materials the rate is £2.50 per ton.

So, the message to everyone is clear, segregate your waste to reduce the volume of waste going to landfill. Traditionally, at home or at work, as soon as you place waste in the bin , it is forgotten about. Someone else will collect it and take it away. Nowadays, at home and at work, recycling is being encouraged through the provision of containers in which to place specific recyclable materials. At home, the children are often the keen recyclers.

Perhaps the most common materials to be seen being collected for recycling are paper, card, glass, metals and plastics. But the opportunity to recycle a vast number of materials or products continues to grow. Although technically not seen as recycling, food waste and garden waste collections are increasing, where the food or garden waste is taken back to a plant for processing into a reusable or saleable compost product.

One of the ways to make sure we won’t vanish beneath a mountain of waste materials is to generate more energy recovering facilities in order that our waste products turns into a valuableresource.

The methods of collecting materials or waste to be recycled is also increasing and becoming more noticeable within local communities. Dedicated collection sites, often referred to as a bring bank sites, are springing up in supermarket car parks to encourage customers of the supermarket to return such items as bottles, newspapers or card to the containers on their way into the supermarket.

Local Authority waste collection crews or their appointed contractors will collect refuse and recyclables from the kerbside usually at the front of your home. Collection from domestic premises generally remains the responsibility of the local council and many have now employed the provision of bins in which to collect specified recyclable materials or products. The services do vary from council to council.

In the industrial and commercial sector, waste management businesses offer separate containers in which the customer deposits the appropriate waste stream or recyclable material ready for collection. The containers will often be clearly labeled as to which recyclable product should be placed within that container or bin. Alternatively, the bins will be colour coded to identify which recyclable wastes should be placed within which bins.

The key to a successful recycling initiative is informing the public about what can be recycled and how. In the commercial world getting the co-operation of office employees is crucial. The introduction of any recycling scheme must ensure that in asking employees to separate waste for recycling, it does not become time consuming and affect the efficiency of what employees should be doing in their work.

The Recycling Process

Various collection systems exist for the collection of the recyclable products . Whichever collection system is used , the materials are taken to a recycling centre where they will be segregated from other wastes. This could be done manually or by using mechanical separators.

To begin the recycling process from a collection point of view, the more recyclable material which can be separated at source, i.e. at home or in the work place, the more efficient it will be for the waste collector. That is why separate containers are supplied to the waste producer to encourage segregation at source. If card can be collected on a vehicle, which will collect no other waste material, the card will be kept uncontaminated and therefore will have a higher value when it reaches the processing plant. Similarly, specialist glass collection vehicles are used to collect only glass. Apart from the obvious health and safety reasons and the weight of collected glass, it will have a much higher value if the collected glass load is not mixed with other waste. Uncontaminated recyclables will have a much higher value than contaminated materials.

Once collected, the recyclable materials can be taken direct to a reprocessing plant, if the load contains only that specific type of material. So a dedicated glass collection vehicle could take the load directly to a glass processing plant.

If mixed recyclables have been collected such as paper and card within the same container, it may be necessary for the collector to take the load to a recycling centre to unload and allow the load to be sorted into separate paper and card bundles for onward transfer to a paper or card processing plant. Whichever method is used, the recyclable material collected will usually be segregated or cleaned before going through to a reprocessing plant to be processed to a new resource and ultimately used as a new product or in manufacturing. Inert materials can be a useful by product at landfill, for example shredded tyres to aid traction on access roads.

All corporations, great or small can be urged to introduce waste recycling systems within their organisations.

The Increasing Importance of Recycling

In the UK around 35% of waste collected from households is recycled or composted. Whilst in the commercial and industrial sector, the volume of waste sent to landfill has declined substantially in recent years and the amount of waste now being diverted for recycling or reuse by this sector has risen above the volumes going to landfill.

Landfill continues to play an important role in the management of waste across the UK as not all wastes can be recycled and some are more suited to landfill disposal than by any other means. However, it’s not just the increasing costs of disposing of waste directly in landfill which is making recycling a more attractive option for businesses. Landfill is becoming scarce, with some experts suggesting that the amount of void available across all UK landfill sites, has less than ten years existence remaining before all sites are deemed to be full. Such countries as Dubai have filled parts of the coastline with their waste and created useful land area to extend the boundaries of their country.

In recent years, waste management companies have had to change their focus, and start to consider and invest in new technologies, such as energy from waste plants, anaerobic digestion plants and mechanical biological treatment plants, as alternatives to landfill. Local Authorities have also changed their attitudes by undertaking detailed strategic reviews as to how waste under their jurisdiction should be handled. In some cases this has meant that unitary authorities are progressing plans to introduce long term contracts, usually around 25 years in length, through which to manage their entire waste management requirements. These contracts will often include the need to build a facility through which to handle all waste generated across the region by sorting all waste streams. The contracts may also include the collection of all waste and recyclables from households across the area. So the issue of waste management is changing rapidly. The days of just throw it in the dustbin have disappeared and the advent of new technologies are upon us.

Conclusion

Recycling is now a way of life and is here to stay. It has evolved over the years from something that was undertaken without any real thought behind it. The trusty rag and bone man was just trying to make a living. Today, many blue chip organisations are setting out plans for a ‘zero to landfill’ waste policy, where the intention is very clear - reduce waste, reuse waste and recycle waste, but no waste must end up in landfill.

Many homes across the country now have some form of container in which to separate waste for recycling. The need to separate newspapers, aluminium cans and plastic bottles are almost common place. Whilst in industrial and commercial sectors, there is an increasing list of items to consider for recycling such as printer cartridges, office paper, metal and electrical equipment.

Ideally the whole process would be a complete cycle such as it was in the days of the horse. However the advent of new technologies will accelerate further the way in which our waste is to be managed in the future, but it is highly unlikely that we will ever reach the ultimate waste free society.

Introduction

Mention the word demolition to almost anyone and the picture that instantly comes to mind is a vision of a building being blown up and collapsing to the ground. Many people have stated that they would love to push the button, to detonate the explosive devices which bring a disused building to the ground. In many cases what comes down, must go up and we are seeing many empty buildings being demolished to make way for future development, often as part of a regeneration project.

For companies who over many years have built their business around the demolition of buildings, the demolition sector is now far more reaching than just blowing up old buildings. Once the building is demolished the huge task of site clearance begins and in a world where consideration of the environmental impacts are high on most peoples agenda, the material residues from demolition need to be sorted for recycling purposes. This will include such materials as steel, wood, plastic, brickwork and concrete.

Most of the materials can be bulked up and transported to the appropriate recycling plants for reprocessing. Materials such as bricks and concrete can be crushed and turned into a recycled concrete aggregate product ready for reuse in the construction of new roads or buildings. Increasingly though, through advances in technological development, residues such as concrete to be recycled have to meet a very high specification for reuse in construction projects.

Crushed into different sizes of recycled aggregate will determine the future usage potential of the product. Large sizes could be used as decorative rockery products in landscaping whilst much finer, almost shingle like product can be used as a bedding for pipe laying or as a layer in road construction. With an increasing number of opportunities identified for the reuse of recycled aggregate, the entire demolition and construction industry is making a significant contribution to sustainable development. Following demolition of a site, many demolition contractors have expanded their service offering to include site clearance services.

Reasons Behind the Increased Focus on Recycling from Construction and Demolition Projects

In 1996, UK Government imposed a tax on all wastes going to landfill. The tax is paid on top of normal gate fees for waste being disposed in landfill and since its introduction the cost has increased on an annual basis. When first introduced, the standard rate of tax for general wastes going to landfill was £7 per tonne and £2 per tonne for inert materials. The tax is designed to encourage commercial and industrial businesses and local authorities collecting from households, to divert waste away from landfill for recycling. In April 2009, the standard rate of landfill tax increased to £40 per tonne and is scheduled to increase each year by £8 per tonne until 2013. The lower rate of tax charged upon any inert materials going to landfill such as concrete and soils, has remained relatively steady in recent years and is currently at £2.50 per tonne.

However, the weight factor alone of a bulk load of these inert materials going directly to landfill will ensure that the entire cost of disposal becomes very expensive and so even in the demolition and construction sector, diverting waste from landfill is a priority. The introduction of landfill tax has been a key driver in encouraging greater diversion of inert materials from landfill, to be used in sustainable development projects.

The materials which remain after making use of demolition equipment is often converted into a variety of reusable products for use in other construction projects.

Next time you see a demolition project in progress or pass any construction site during a build programme, it is clear to see the volume of waste being generated. If waste is not in skips, piles of rubble will be stacked high. The placing of brick waste in skips has been a major problem for waste contractors for many years. Having worked in the waste industry, I have seen skip lorries tipped backwards with the cab of the vehicle up in the air, due to the sheer overloading of waste skips with construction site waste.

Each year, the UK generates around 330 million tonnes of waste and it is estimated that around 90 million tonnes of this is from construction and demolition wastes. This figure has remained fairly constant since 2001. Around two thirds of this waste is usually recycled or reused in land reclamation or agricultural improvement projects. Since the late 1990s there has been a steady rise in the volumes of construction waste being recycled and this has been helped with advances in technology which have led to improved crushing technology to create more widespread use of different grades of recycled aggregates. There has been a real focus upon the UK construction industry to encourage greater recycling of waste on site.

In recent years, the construction industry as a whole has worked hard to encourage construction project managers to place a greater emphasis upon recycling on site. This has led to an increase in the recycling of all inert materials from site.

Prior to the introduction of the landfill tax all construction site waste including bricks and concrete would be bulked up and transferred to a landfill site for disposal. No consideration was given to recycling. There are now stringent regulations across the sector, coupled with an increase in environmental awareness, as well as the commercial benefits in ensuring that this type of waste is now recycled. There is also greater recognition of the vast array of opportunities to re-use recycled aggregates within the construction process on future construction projects or in areas such as landscaping or home and garden DIY. Following the demolition process, together the waste concrete, bricks, masonry etc will be transformed into a recycled concrete aggregate. Recycling of aggregates has become a common process for demolition contractors.

To recycle concrete aggregate to a high standard and resalable product, it must be entirely free of other contaminants such as wood, paper, card, steel and other general waste materials. The final product must also conform to the requirements of British Standard BS 8500. The process of recycling the concrete can usually be achieved in one of two ways. Some demolition contractors will locate a crushing machine on the demolition site, whereas some contractors will prefer to transport the waste to be recycled, back to their own premises for sorting for recycling or re-use. On projects where demolition and new construction is to take place at the same location, the contractor is very likely to locate a crushing machine on site to avoid incurring additional transportation costs in taking the material back to a sorting and crushing facility.

Approval from the local authority will likely be required before site clearance contractors commencing the task of demolishing a building.

The Increasing Demand for High Quality Recycled Aggregate

Before commencing the crushing process, it must be determined what the end product is to be used for to ensure that the recycled aggregate is to meet the required standards. There is huge demand for recycled aggregate to be used back in the construction process. As a product, recycled concrete aggregate can be used for almost any type of concrete structural work, road surfacing or pipe laying project. Having passed through the crusher the chunks of aggregate will be separated by size. Bigger pieces may be retained as a decorative product for use in garden rockery projects, or they may be passed back through the crusher to be pummeled to a smaller size. The smaller pieces of recycled aggregate may be suitable for use as a gravel on new construction projects, road laying or driveways at home. The crushing machines are now capable of achieving good quality small aggregate grades such as the production of a 20-5mm gravel which can be bagged and used in the garden at home or bought in bulk as part of projects involving new concrete production. The advances in technology mean that the recycling of aggregates for other uses such as a simple gravel product or for use in concrete products has greatly reduced the need to dig quarries to mine for gravel.

The demand for high quality crushed aggregate is increasing. There are key standards in place which are focused upon improving the recycled aggregate industry. Through research and development, more widespread uses are being identified for the use of recycled aggregate. No longer is concrete, just concrete. What we are talking about now are many different grades of recycled aggregate, ranging from the large chunks of aggregate to very specific 6f2 recycled concrete which can be used as a sub-base material for construction jobs, or 20-5mm recycled aggregate, which is a gravel and can be used in road construction or at home on driveways. As well as being used as a mix for road construction, recycled aggregate is being used as bedding for pipe laying or foundation material prior to construction projects commencing. In achieving such good quality grades the 20-5mm recycled aggregate can be used as an aggregate base in road construction and the quality meets the standards required to allow its reuse in concrete production.

One of the important criteria when using recycled aggregate is selecting the right specification for the task. For example, when using 20-5mm coarse graded aggregate as a road base, the thickness of the layer required must be determined to withstand traffic flows. Traffic flow on a motorway will be significantly different to that of a country road. One reason aggregate produced to a 20-5mm specification is used as a road base is that it aids good drainage. Once the recycled aggregate is laid, appropriate layers of asphalt or concrete can be laid over it to create the road surface.

In recent years, in the UK we seem to have more rain than sunshine and therefore the selected aggregate must be able to withstand variances in temperature and conditions e.g. dampness for long periods, torrential downpours, long dry spells. With its good drainage qualities, the recycled 20-5mm product is the perfect choice for many sand and gravel applications including, pipe bedding, driveways and footpaths, landscaping, plus for use in ready mixed and precast concrete products. With its drainage qualities, 20-5mm recycled aggregate is a versatile product.

The build programme for London’s Olympic Village, has specified the use of a clean recycled concrete aggregate crushed to a 20-5mm specification.

Recycled Aggregates and the 2012 Olympics

In its bid for the 2012 Olympic Games, London placed sustainability as the focal point of its bid. The bid team identified a major opportunity to increase awareness of climate change and the issues which surround it, and bring it to the World’s attention. With the eyes of the World watching, the Olympic Games present a unique opportunity to communicate key messages about sustainability. Throughout the entire development of the Olympic project, there is a commitment to make 2012 the most sustainable Olympic Games ever held. This focus began when planning the development and build programmes for the facilities and venues, the transport links and network, the hosting of the Games themselves and will end by leaving a long lasting legacy of a sustainable environment.

Since London was awarded the Games, all suppliers involved in the development requirements, from the construction of the Olympic Stadium, the Olympic Village and transport links to the venues have been focused upon ensuring the use wherever possible of sustainable materials. Across the entire Olympic build programme developers have worked hard to identify suitable sustainable materials for use in the build programme. At the end of the overall project there will be some clearly visible examples of the use of sustainable products.

qually there will be many more much less visible and furthermore, many which will be not visible at all. One of those products which visitors to the games and its many venues will not even think about will be how recycled aggregates have been employed as part of the overall construction project. But developers and specifiers of materials for use in the build programme will be comfortable in the knowledge that they have selected sustainable products including, the most appropriate recycled aggregates as part of the project. With its identified qualities, let’s hope that somewhere in the world wide TV coverage the 20-5mm recycled aggregate gets a mention somewhere, somehow. Imagine being asked to supply recycled aggregate which meets a very specific 20-5mm clean material specification, to help build the 2012 Olympic Village.

Conclusion

How times have changed in recent years for the demolition and construction industry. Companies have had to adapt to meet challenging environmental requirements. As with almost any industry, new regulations and legislation dictate the standards to which your business must aspire, if it is to be successful.

Businesses involved in the production of recycled aggregate are no different. These are classed as processed materials and must conform to a particular product specification which can be used in the construction process. The standard BS8500-2 offers a full specification for the uses of recycled concrete aggregates in concrete, although with such a vast range of recycled aggregates an all encompassing specification for the use of these aggregates is yet to be determined. The most important thing is that the industry does not stand still and wait for the specifications to be finalised. The versatility of recycled aggregates means that demolition contractors operating crushing plants are seeking to identify markets through which to sell their recycled products. The advances in crusher technology and machinery has seen a big increase in the options now available in supplying large chunks of recycled aggregate for landscape gardening use in rockeries, down to a gravel type 20-5mm recycled aggregate with its good drainage qualities for use in road construction and driveways. The demolition and construction industry now places sustainability at the forefront of its future development projects.
