Waste that is not segregated and runs to the end of our processing systems is diverted into energy usage rather than landfill. Although this waste does not have a value in terms of recycling, it still has a calorific value and is therefore suitable as an energy source. It therefore undergoes additional processing to change it into a Solid Recovered Fuel (SRF), and is diverted from landfill.

SRF WASTE

Solid recovered fuel (SRF) is a high quality alternative to fossil fuel produced from mainly commercial waste including paper, card, wood, textiles and plastic. Solid recovered fuel has gone through additional processing to improve the quality and value. It has a higher calorific value than RDF and is used in facilities such as cement kilns.

MacNabb Waste are proud to be partnered with Geocycle UK for the supply of SRF into the LaFarge plant in Cookstown, Northern Ireland. Geocycle believe in a zero waste future just like ourselves at MacNabb Waste. Their approach is to find the most cost-effective, sustainable solutions to minimising and re-purposing waste for customers and society at large. https://www.geocycle.com/

Wood Waste recycling

Around four million tonnes of waste wood is generated in the UK each year, deriving from construction & demolition, commercial & industrial and household sources.

Industry, electric power producers, and commercial businesses use most of the wood and wood waste fuel consumed in the UK & Ireland. The industry uses wood waste to produce steam and electricity, which saves money because it reduces the amount of other fuels and electricity that must be purchased. Some coal-burning power plants burn wood chips to reduce sulfur dioxide emissions.

Biomass Power Plants are fueled with recycled wood, a fuel which otherwise would have to be stored on a landfill. It is a Combined Heat and Power (CHP) plant based on a steam / turbine cycle with relatively advanced steam parameters. The process is virtually carbon neutral; the combustion of the recycled wood only releases the carbon dioxide that the wood absorbed from the atmosphere during its growth which saves the CO2 emissions which otherwise would have been released from burning fossil fuels to generate the same amount of electricity.
