Biomass Production

Every year five million tonnes of waste wood is generated in the UK and year on year we have seen a rise in how much of that is recycled or reprocessed due to increases in landfill taxes and a Government drive to recycle more. Uses for recycled waste wood include traditional feedstock for the panel board industry, which still accounts for the majority of recycled wood, as well as animal beddings, equestrian and landscaping surfaces, play areas and filter beds. However, more recently there has been a huge growth in the reprocessing of waste wood into biomass fuel, both at home and with exports to Europe, changing the face of wood recycling as we know it.

Biomass timber can be classified into four categories:

• Grade A — These are clean, non-hazardous waste woods. They are usually a by-product of arboriculture activities, packaging, scrap pallets and off-cuts from untreated wooden materials. To turn this to biomass energy, it goes through an industrial biomass boiler.

• Grade B — These are non-hazardous waste woods usually from manufacturing wood-based panels like chipboards and fibreboards. Processors convert it to biomass energy by putting it through a Waste Incineration Directive (WID) and Industrial Emissions Directive (IED)-compliant industrial biomass boiler.

• Grade C — These consist of non-hazardous waste woods from construction and demolition activities and recycling centres. Like Grade B waste wood, a WID (IED)-compliant industrial biomass boiler should be able to process it.

• Grade D — These include waste woods treated, coated or painted with a hazardous chemical, such as chrome, copper, arsenic, creosote or halogenated compounds. Turning this into biomass energy would require a hazardous waste incinerator.

Biomass at Skips R Us

At Skips R Us we produce two products, and it is the same process employed to manufacture both biomass fuel and animal bedding, the difference being the material feedstock. Animal bedding can only be manufactured from Grade A material whilst Biomass fuel can be made from a mixture of grades A, B and C and this mix will depend on the receiving facility on what they are licensed to accept.
Skips R Us operate in compliance with the quality standard of PAS 111 – (Specific action for the requirements and test methods for processing waste wood).

Inbound waste timber is pre-sorted into its respective grade prior to shredding, and dependant on the requirement of the end customer. The respective material is shredded using Skips R Us ltd.’s Doppstadt AK510 Multi II timber shredder which is fed using a 360° material handler equipped with a hydraulic grab and high-rise cab. The use of the high-rise cab allows the operator to closely monitor the shredding process. Ferrous metals are also removed at this stage with the use of an overband magnet. The shredded material can then be further screened to the size requirements of the end user through our Colt 800 screener.

Skips R Us produce biomass from waste timber that arises from a variety of commercial, industrial, local authority and domestic sources. If you have a supply of waste wood or timber and require a processing outlet, then please get in touch. Similarly, if you need a supply of biomass for energy generation Skips R Us have a constant supply for your needs.
