Channel 5: "How Do They Produce Compost from Domestic Waste?"

The NLWA has said it wants to use either 'composting' or 'anaerobic digestion' at Pinkham Wood.

(Link to an example in Spain about the alternative, anaerobic digestion.)


"This composting plant near Poole in Dorset takes in 30,000 tonnes/year of 'black-bag' waste. The organic component is separated and then composted." (Pinkham Wood is supposed to take ten times that quantity. The North London Waste Authority suggests  "either composting or anaerobic digestion" would be used at Pinkham Wood.)

"The Poole plant also takes 20,000 tonnes/year of food waste. In total, about 25,000 tonnes/year of compost in produced." (The NLWA says that food waste "would not travel to Pinkham Wood".)

"Robert dons protective clothing and breathing gear to visit a recycling centre in Canford, near Bournemouth. This state-of-the-art facility transforms 30,000 tonnes of rubbish into rich compost every year. Compost normally takes a long time to prepare, but this facility speeds up the process. 

After just eight days, the compost is ready to be turned over – using a gigantic tractor with spinning blades. A few weeks later, the compost is ready to serve as ordinary garden mulch."
