Turning Waste into Wealth

“Kitchen waste is highly organic, greasy, salty, perishable, and contains lots of water. It can produce lots of leachate which can pollute underground water and surface water. This kind of waste accounts for 50% to 60% of household refuse.” Zhang Zhiqiang, who starts his own business, shows his interest in processing kitchen waste into bio-organic fertilizer with bio-technology, which is then returned to farmland. In this way, waste can be turned into wealth.
