Earthworms, mushrooms and zero waste in China: China's 'mushroom town' of Qingyuan illustrates new ways to profitably reuse agro-industrial residues - and a great potential for earthworms
Article Abstract:
60% of the revenue of farmers in Qingyuan in China is from mushrooms. The region products 10,000 tons a year of shiitake mushrooms with a trading value of 170 million Yuan. Large volumes of substrate are required for mushroom production, and the use of hardwood chips led to overharvesting of trees and deforestation. Mushrooms are now grown on agro-industrial wastes, and the spent substrate is used as fuel by farmers. Another option is to grow earthworms as the substrate is rich in protein, which will convert into animal protein.

Recycling food residuals into animal feed
Article Abstract:
There is increasing interest in using food residuals for animal feed. Companies involved in food residuals for animal feed have had to face challenges such as collection methods, procurement, and competing with haulers. Griffin Industries processes bakery residuals into animal feed and has designed specialized collection systems for the material. Thermo Tech Technologies has plans for a further six facilities, and Camden Agro Systems of Canada is planning to start up an animal feed project in Lakeland, Florida.

Zero waste system in paradise: Boys school on the island of Fiji uses an integrated biosystem to produce vegetables and animal feed from brewery and sugar cane processing
Article Abstract:
Montfort Boys Town Integrated Biosystem (IBS) on the island of Fiji was designed by Professor George Chan of the United Nationals UNiversity in Tokyo, together with Zero Emissions Research Initiative (ZERI) Foundation. It was designed to accommodate spent grain from beer breweries, but can also accept bagasse from sugar cane processing. The raw material grows shiitake, oyster and straw mushrooms which break down the structure of the substrate, yielding a residue which provides feed for pigs.
