Waste Management

 

The principal objective of waste management is to maximise the potential for recycling waste materials and reduce the amount of waste being removed to landfill. During the pre-construction phase, we can produce a Waste Management Strategy plan bespoke to each project which will identify the waste streams that will be generated during the life of the project and define ways to mitigate these waste streams.

During the implementation phase, we will operate the following waste reduction methods,

  • education and training of site operatives (i.e. tool box talks and presentations);

  • production of KPI reporting tools and performance charts;

  • encourage reward schemes for good performance and initiative.

We will categorise all elements of waste, record all vehicle movements and prepare transfer notes and weighbridge tickets to record all activities to provide a chain of custody records. We have tried and tested partnering arrangements with various hauliers to receive waste for recycling. We will create material re-use areas, provide colour coded waste stream identification signage and provide specific equipment for storage and treatment of waste (e.g. balers for plastic / cardboard / food,  de gassing units for hazardous waste and plasterboard chippers). We will also initiate take back schemes for unused materials and packaging and assist contractors in ensuring standard material sizes are ordered which are pre-cut or modularised if possible.

Our methods are successful because we understand the nature of the construction activities generating waste and we have qualified Waste Managers dedicated to the implementation of the waste management plan. Our Waste Manager will generate monthly waste reports which will be issued to the project team and identify recycling key performance indicators.  Using our network of local waste hauliers and transfer stations, data will be collated and fed into these reports to produce realistic figures against which compliance with the plan can be measured.

All unauthorised waste will be digitally photographed, recorded and reported to the Waste Manager who will issue clean up notices to offending parties. If the offending parties fail to remove the non-compliant waste to the designated bins within the agreed timescale, we will do so on their behalf and administer contra-charges accordingly.

Recycling

Our Waste Manager will co-ordinate the recycling of waste materials on site. The most common materials that fall into this category are plasterboard, wood, metal, glass, cardboard, paper, plastic and food.

Plasterboard

Waste plasterboard is relatively easy to recycle to either make new plasterboard, to use as a key ingredient in plaster, to use a basic form to help grow mushrooms and to improve the quality of soil for farmland.

Wood Waste

It is estimated that construction activities produce 750,000 tonnes of wood waste each year with packaging waste/pallets and crates accounting for a further 670,000 tonnes. Waste wood chips are useable in the particle board manufacturing industry, animal bedding, gardens, children’s playgrounds and horse arenas / running tracks. However, the main emerging volume market for wood chips is energy generation.

Metal Waste

Virtually all metals can be recycled into high quality new metal helping to protect the environment by saving energy, reducing CO2 emissions and using less natural resources which would otherwise be needed to manufacture new metal compounds.

Glass

Glass waste that is discarded and ending up as landfill material will never decompose and hence it is vital that glass waste is properly segregated and removed from site for recycling. The energy saved by recycling one bottle alone will power a computer for 25 minutes.

Cardboard

Cardboard is made from cellulose fibres which are created from wood pulp. To reverse the process for the purpose of recycling, the cardboard is soaked and agitated to release the fibres which can then be pulped. It can then be made back into raw cardboard at a number of mills in the UK.

In its shredded form, cardboard can be used for animal bedding and to insulate houses. It is also being used in the green market place for bio degradable coffins. As it releases twice as much heat per pound of waste compared to other sources, doesn’t release toxic poisons and its only by-product is ash, cardboard is an excellent material for use in the developing area of creating energy from waste.

Paper

Recycled paper produces 73% less pollution than if it was made from raw materials. White paper has the highest environmental value because it can be used by paper mills as a virgin pulp substitute, reducing the demand for trees throughout the world. Mixed office paper can be taken to a paper mill where it is recycled back into high grade copier paper.

Plastic

Plastic can take up to 500 years to decompose and more energy is saved by recycling plastics than is gained by burning them. Waste plastic bottles on site are collected by our Clipfine operatives and separated by the specialist equipment into ‘clear PET’ and ‘cloudy HDPE’ sections. The PET plastic bottles are washed and flaked from which the flakes can be spun into fibres for clothing or carpets. Recycled PET and HDPE plastic can be made back into new plastic containers. The remaining sundry waste plastics can be converted into new building materials such as drain pipes and ‘Plaswood’.

Food Waste

We offer a simple and hygienic food waste recycling service tailored to small and large projects as well as commercial kitchens. We provide a range of containers from 240 litre bins for large producers requiring daily collection to small offices needing a 40 litre caddy emptied weekly.

We use anaerobic digestion (AD) to convert food waste into biogas and liquid bio fertiliser. The biogas is used to produce clean renewable electricity and the bio fertiliser is spread onto farmland. AD is recognised by the UK Government and Friends of the Earth as the best method for recycling food waste. In addition, Canteen cooking oil can be processed (heated, cleaned and then filtered) at one of our purpose built depots then it is transported to a processing plant for conversion to bio diesel.
