- Description: Abstract: An engineered landfill presents an opportunity for proper waste management that allows resource recovery from waste. However, for this to be achieved several technical parameters must be considered when designing a sanitary landfill. These technical parameters include proper site selection with minimal environmental and hydrological negative impacts, selection of a liner network that will not allow the leachate to infiltrate into the ground. Furthermore, there is need to have an integrated network for monitoring the movement of the waste as well as quality of the leachate. The surface drainage at a landfill site must also be well understood as well as daily covering measures to avoid pests and pathogens coming outside the designated landfill site. Although, landfills present a potential for proper municipal waste management, the human capital aspect is also critical and must be considered.

- Description: Abstract: In this study, maize waste and soy bean residue were vermicomposted as a way of harnessing bio products from agro waste in a bid to promote sustainability and proper waste management to bio fertilizers. Maize and soy bean residues were vermicomposted in a 9m by 1m vermicomposting bed over a period of 30 days using Eisenia Fetida earthworms at standard conditions. The physicochemical parameters of the organic waste including the organic loading (OC), nitrogen, phosphorous and potassium (NPK) content as well as trace elements such as calcium (Ca), magnesium (Mg) and sodium (Na) were determined using standard methods. The behavior of the earthworms in terms of mass and length was also quantified. Upon increase in the vermicomposting period, the OC increased by 38%, NPK composition by 50%, 50% and 35% respectively. The Ca, Mg and Na composition by 10%, 23% and 30% respectively. The earthworms mass and length increased by 60% and 20% respectively. From the results obtained, vermicomposting offers a sustainable opportunity for crop waste management to bio fertilizers.
