关闭养分回收循环、支持“循环经济”、改善废物行业的成本回收以及通过将废物转化为有机肥料创造可行的企业具有巨大的潜力。然而，废弃物有机肥业务的成功商业化很大程度上取决于良好的市场。我们使用选择实验来估计乌干达坎帕拉农民对粪便污泥和城市固体废物堆肥（FSM）的支付意愿（WTP），并考虑了三个属性：强化、颗粒化和认证。我们的结果表明，农民愿意为 FSM 堆肥付费，并对“经过认证”的堆肥产品给予更高的重视。他们愿意为类似的认证产品支付每公斤比当前市场价格高 0.4 美元的价格，这比提供该属性的成本高出 67 倍。农民愿意为“颗粒化”FSM 堆肥支付每公斤 0.127 美元，这比提供该属性的成本低（0.57 倍）。另一方面，农民要求每公斤 0.089 美元作为使用“强化”密克罗尼西亚联邦堆肥的补偿。我们建议未来的 FSM 堆肥业务重点关注“经过认证的颗粒化”FSM 产品，因为这种产品类型具有最高的生产成本 - WTP 差异，并且未来的业务可以获得最高百分比的消费者剩余。对密克罗尼西亚联邦堆肥的需求表明，农业有机废物的回收可以给农民、企业和环境带来好处。
There is a great potential to close the nutrient recycling loop, support a ‘circular economy’ and improve cost recovery within the waste sector and to create viable businesses via the conversion of waste to organic fertilizers. Successful commercialization of waste-based organic fertilizer businesses however largely depends on a sound market. We used a choice experiment to estimate farmers’ willingness-to-pay (WTP) for faecal sludge and municipal solid waste-based (FSM) compost in Kampala, Uganda and considered three attributes—fortification, pelletization and certification. Our results reveal that farmers are willing to pay for FSM compost and place a higher value on a ‘certified’ compost product. They are willing to pay US $0.4 per kg above the current market price for a similar certified product, which is 67 times higher than the cost of providing the attribute. Farmers are willing to pay US $0.127 per kg for ‘pelletized’ FSM compost, which is lower (0.57 times) than the cost of providing the attribute. On the other hand, farmers require US $0.089 per kg as a compensation to use ‘fortified’ FSM compost. We suggest that future FSM compost businesses focus on a ‘certified and pelletized’ FSM product as this product type has the highest production cost–WTP differential and for which future businesses can capture the highest percentage of the consumer surplus. The demand for FSM compost indicates the benefits that can accrue to farmers, businesses and the environment from the recycling of organic waste for agriculture.
