Food Waste to Livestock Feed: Prospects and Challenges for Swine Farming in Peri-urban Sri Lanka.

Using farm animals for their natural capability of "recycling" food waste (FW) that is unfit for direct human consumption can support a circular economy as shown in the case of Sri Lanka's Western Province. The reuse of organic residues including FW as animal feed is a traditional agricultural practice in Sri Lanka but is less studied within an urban FW context. A survey of piggeries using FW in and around the rapidly urbanizing city of Colombo showed that FW is a major feed source in the farms accounting for on average 82% of total feed.

The contribution of tipping fees to the operation, maintenance, and management of fecal sludge treatment plants: The case of Ghana.

Globally, collection of tipping fees is being promoted as a solution to sustain the operation of fecal sludge treatment plants (FSTPs). Currently, there are six large-scale FSTPs in Ghana, of which five were in operation in June 2017. In Kumasi, Sekondi-Takoradi and Tamale, fecal sludge (FS) is co-treated with landfill leachate using waste stabilization ponds (WSPs).
