Refuse Derived Fuel (RDF)

Refuse-derived fuel (RDF) is a fuel produced by shredding and drying out every day rubbish (MSW). When a waste collection arrives back at our depot waste materials from a collection are processed to remove the non-combustible materials such as glass and metals. These items are recycled separately.

The materials that are left consists largely of organic, plastic and biodegradable waste that is then ground up and dried out in the processing station before being compressed into large pellets or bricks which are then sold on to another processing site that in effect burn the pellets and harness the heat that they give off into an energy source.

Material removed before the RDF process, such as metals and plastics, are then sent to one of CD Waste Management Ltd’s approved sites to be recycled accordingly.

Materials Recovery Facility (MRF)

CD Waste Management Ltd also utilise a MRF for processing our Dry Mixed Recycling collections. This unique machinery acts as an automated production plant using advanced technologies such as trommels, ballistic separators and optical sort machinery our facilities can accept a complete range of mixed recyclable material (all grades of paper, cardboard, plastic, aluminium cans, glass etc.) from one receptacle e.g. Wheelie Bin.

An example of the advantage of this system is that the average Dry Mixed Recycling bin can be emptied onto the machine and the different types of waste will be separated into categories such as glass, plastics, paper etc.

While many recycling services require you to segregate waste into different bins, our innovative solution allows you to put all your Dry Mixed Recyclable waste into one container. Provided it is not contaminated by other waste, especially food, it can be converted into reusable commodities at our own Recycling Facility.

The Dry Mixed Recycling bin is often used alongside a General Waste bin that may be used for “Residual Waste” containing food contaminated waste. By using DMR bins, our customers save money as we offer cheaper rates for collecting these containers.

All separated waste streams are then taken to approved sites that specialise in a specific stream of recycling such as glass or plastics, where they are processed and then sold to manufacturers that use the material in their products.

We offer a wide variety of recycling containers to suit your business and save you space. Our experienced consultants will carry out an inspection of your waste to identify the opportunities to increase the amount of waste you recycle whilst potentially saving you money in the process.

Food Waste Recycling

Once we have collected your food waste, it is taken to a special processing plant where it is treated in an enclosed vessel. Anaerobic digestion (AD) is a biological process that produces a gas principally composed of methane and carbon dioxide otherwise known as biogas. These gases are produced from organic wastes such as meat and fruit.

Anaerobic processes could either occur naturally or in a controlled environment such as a biogas plant. Organic waste such as food and various types of bacteria are put in an airtight container called a digester so the process can occur. Depending on the type of organic waste and the system design, biogas is typically 55 to 75 percent pure methane.

The biogas is used in a combined heat and power plant or cleansed of carbon dioxide and injected into the National Grid.

A by-product of the AD process is digestate. Digestate is a stable, nutrient-rich substance that is most commonly used as a renewable fertiliser or a soil conditioner which will be used for horticultural purposes on farms as a highly valuable addition to fertiliser.
