A study in 2009 showed that producing particleboard out of recycled wood resulted in a 77% energy saving compared with making it from virgin wood.A 2000 study by the US EPA shows that recycling is a more energy intensive option to incineration, whilst incineration gets an energy credit. As a result, incineration presents an advantage over both recycling and landfill (an advantage of over 150%) from this perspective.

Although from a climate change perspective, recycling is the best option, performing 70% better than incineration , and 80% over landfill.

The overall conclusion from the WRAP report seems to say that, overall, incineration with waste recovery brings more of an energy credit, whilst recycling appears more advantageous when it comes to ‘climate change’ potential – mainly through the idea that less forest is chopped down if the wood waste is recycled in a closed loop recycling process.

The UK generates about 5 million tonnes of wood waste each year. In 1996 less than 4% was recycled. By 2010 that figure had risen to 55%, or about 2.8 million tonnes. However, this is reported, in 2009, as still being low incomparison to other recyclate products such as metals. Uses for recycled wood include traditional feedstock for the panel board industry, which still accounts for the majority of recycled wood. Other uses include animal beddings, equestrian and landscaping surfaces, play areas and filter beds. However, it is the emerging biomass market that is set to change the industry of wood recycling in the future.

Quantifying the benefits

There is a positive net CO2e saving benefit of recycling versus landfill, according to Defra Guidelines for GHGs in 2011, of 1.224 tonnes of CO2e for each tonne of woodproduct recycled.When comparing closed loop recycling to incineration with heat recovery, the GHG benefits per tonne of Wood product are -523 kg CO2e for recycling and -817kg forcombustion with heat recovery.

Defra do not give a figure for open loop recycling. If we compare production emissions for wood products per tonne of product (excluding disposal) we see each tonne of woodproduct emits 666 kg CO2e. Compared with closed loop recycling of Wood waste of -523kg CO2e. Hence we can say that for every tonne of closed loop recycled product, we are saving 1.189 tonnes of CO2e in virgin product.

Recycling one tonne of wood product instead of sending to landfill saves, on average, 1.224 tonnes of CO2e. So Shanks, by recycling ~34,500 tonnes of Wood product in 2011, is saving 42,228 tonnes of CO2e each year in avoided landfill
