Advanced treatment of recycled organic matter

环境工程师为社会工作，消除或最大限度地减少与人类活动相关的负面环境影响。堆肥系统已被确定为一项关键技术，有助于将废水中的有机物质回收到土壤中。在为可持续社会设定的目标的推动下，堆肥行业在过去十年中取得了戏剧性的增长。从大型中央堆肥设施的都市固体废物(MSW)流中回收的有机物数量现已超过每年200万吨，自2000年以来增长了105%。加拿大生产的可回收有机物质(ROM)总量要高得多，因为MSW数据不包括纸浆和造纸工业废物、农业废物或城市生物固体。例如，加拿大牲畜粪便是一种常见的堆肥原料，据估计每年的产量为1.775亿吨。

Environmental engineers work for society eliminating or minimizing the negative environmental impacts associated with human activities. Composting systems have been identified as a key technology to help recycle organic matter from our waste streams to our soils. Driven by goals set for a sustainable society, the composting industry has seen dramatic growth in the past decade. The amount of organic matter recycled from the municipal solid waste (MSW) stream at large-scale centralized composting facilities has now exceeded 2 million tonnes per year and has grown by 105% since 2000. The total amount of recycled organic matter (ROM) produced in Canada is much higher, as the MSW data do not include pulp and paper industrial wastes, agricultural wastes, or municipal biosolids. For example, the production of livestock manure in Canada, a common composting feedstock, is estimated to be 177.5 million tonnes per year.
