According to the World Resources Institute, “Stopping deforestation, restoring forests and improving forestry practices could remove 7 billion tons of carbon dioxide annually—the same as taking 1.5 billion cars off the road.” Now, World Bank figures on global waste production show that there is somewhere about 1.5 billion tonnes pa of MSW (Municipal Solid Waste). About half of that would be Carbon which, as Carbon dioxide, would be around 1.4 billion tonnes. Industrial waste production globally could easily double that, probably more. If that waste was composted, instead of burned or land-filled, it would not only lock up the Carbon, it could be used to fertilise the tree and crop growth. It would also save wasting at least 21,000 kW hours on producing every one of the 185 million tonnes (FAO figures) of Nitrogen nutrient in the fertilisers we manufacture every year. (Yes, that is 385,000,000,000 kWh – at least!)
Only farmers and foresters have the skills and scale to do these things. Better respect and care for them.
