Guangzhou implements a trial run of its first food-waste treatment plant

Guangzhou Daily News
March 24, 2010

Yesterday, Guangzhou implemented a trial run of its first food-waste treatment plant, located on Yanling Road, in the Yuexiu District, representing the first time the Guangzhou Municipal Government has put into operation a treatment plant for food-waste.

Project Leader, Mei Yaowu of Beijing’s Jiabo Wensheng Bio-Technology Co., Ltd., introduced the plant with its total of three “machines,” and disclosed that the investment in the food-waste plant totaled over 2 million Yuan. Each of the three “machines” will be able to dispose of 400 kilograms of food-waste every 8 hours. The food-waste treatment plant is expected to be fully operational starting on March 26, 2010.

A reporter on the scene yesterday saw garbage transported to the treatment plant after the initial stage of manual sorting. After the larger garbage items such as beverage bottles, plastic plates, and plastic bags were sorted out of the mix, the rest of the food-waste was thrown into the “machine” along with corn bran, peanut shells and other materials, used to change the moisture content of garbage. “China’s food-waste moisture content is high, we want to reduce it from its current moisture level of 85% to 60% since a lower moisture level it is more suitable for fermentation.” Wu said that at the same time, staff would also like to add a 1:10000 ratio of high-temperature composite microorganisms, after an 8-hour exposure to high-temperature oxygen, the degradation of the fermentation process, the decomposition of plant protein and animal protein digestion, the final output of the high energy, high-viable, high-protein microbial regeneration of colonies, further deep-processing and manufacturing into a bio-feed or microbial fertilizer microbial agent applied to ecological farming and organic farming.

Currently, technical staff says that the output from the food-waste treatment plant will be useful for the “Nongjiale” project (I think this means something along the lines of rural development –BG), to find outlets for these fertilizers. One ton of food-waste, after being treated through this food-waste treatment plant, can result in the output of 0.6 tons of recycled colonies. After further processing output of fertilizer can replace chemical fertilizer use, which not only helps to improve soil, but also reduces the price of conventional fertilizer products. Wu further stated that in October, they will launch another type of disposal technology that aims at the disposal of individually-generated garbage.
