Curbside Organic Waste Collection and the 60 percent Waste Diversion Goal: A Case Study of Select Municipalities in the Greater Golden Horseshoe

Stauch, Aaron Matthew January 2012 (has links)
Ontario has provided an interesting canvas for waste management planning. As the home of the world’s first blue box program, a successful deposit return system, an extended producer responsibility initiative, and recently the Green Energy Act: Ontario presents many opportunities and challenges for a waste management planner. In addition to the above, Ontario is expected to grow significantly (through immigration) over the next 25 years. In order to manage this, the government of Ontario has created a significant urban planning hierarchy and has focused efforts to accommodate this growth in the Greater Golden Horseshoe. To address the management of waste in the province, the government, in 2004, established a 60% waste diversion goal by 2008. When evaluated in 2009 the province had yet to make significant progress toward the target. This thesis seeks to examine how municipalities in the Greater Golden Horseshoe have developed and implemented their organic waste diversion program in response this target, and examine the issues that arose in reaching it. This thesis attempted to interview waste management planners at eight municipalities, with five agreeing to participate. Based on the interviews it was determined that each of the municipalities had used several different approaches to organic waste diversion, with most having recently implemented (pilot or full scale) curbside organic waste collection programs (green bin). It was also determined that many of the municipalities replicated the same steps as neighbouring municipalities and did not always factor in other’s learning. Most importantly, while the government set the waste diversion goal, they did not take responsibility for ensuring that outcomes were achieved.

Study on the Recovery and Treatment of the Food-Waste

Yang, Hung-wen 28 August 2006 (has links)
According to the statistics of ¡§Annual Report of Environment Protection in Taiwan, the Republic of China¡¨ published by the Executive Yuan, the percentage of food waste and organic garbage amount to about 20-30% of ordinary family garbage, where the food waste is about 10-15% of ordinary family garbage.To recycle the wastes, an effective method of collecting and processing food waste in order to achieve the goal of garbage reduction depends on the cooperation of civilians. The food waste collected will be processed through composting, hog-feeding, or anaerobic decomposition. The composting treatment can be divided into anaerobic and aerobic methods. Aerobic composting process is to make use of turning, forced blowing or suction of air in order to supply oxygen. Major process is based on aerobic decomposition to cause the stabilization of organic material. As the reaction speed is fast, the processing time can be drastically reduced and is thus called ¡§high-speed composting process¡¨. Presently there are already many researches in the method of processing food waste that could complete composting products within the shortest time. The result of this study shows if the collection, transportation, treatment, and recycling processes can be properly planned and promoted, the civilians tend to cooperate and the amount of waste recycling can be significantly increased. In addition, by controlling living condition of fungi including moisture content, temperature, PH value, and volatile solid through evaluating primers of superior fungi, the investigation of the food waste processing efficiency and its influence shows there is a trend of significant reduction in the amount of volatile solid material with time.This indicates the phenomena of food waste being decomposed by fungi. The estimation of decomposing speed for food waste is in the range of 2.08¡Ñ10-4 ~ 1.00¡Ñ10-2 kg/hr and the average speed is 2.87¡Ñ10-3 kg of food waste per hr-kg of fungi. The efficiency of treatment is about 50% of the result of original Japanese plants.
