This study investigated the benefits of an on-site sustainable solid waste treatment and utilization system for the greenhouse industry. The composts made from greenhouse wastes were tested and found to contain high nutrient values and good physical properties, and could be used as high quality growing media. The finished composts were tested in a greenhouse against the conventional growth media (sawdust) and resulted in a 10% yield increase by using the compost. An economic analysis was conducted to show the economic benefits of on-site composting for a greenhouse operation. Based on a four-hectare tomato or pepper greenhouse, and amortizing the capital equipment over five years, the net annual cost of composting represents a savings of dollars 8,000 annually.
本研究调查了温室产业现场可持续固体废物处理与利用系统的益处。对由温室废弃物制成的堆肥进行了测试，发现其含有高营养价值和良好的物理性质，可作为优质种植介质。在温室中，将成品堆肥与传统种植介质（锯末）进行对比测试，结果表明使用堆肥可使产量提高10%。进行了一项经济分析，以展示温室运营现场堆肥的经济效益。以一个四公顷的番茄或辣椒温室为例，并在五年内摊销资本设备成本，堆肥的年净成本意味着每年节省8000美元。
