The recycling of rural and urban organic waste materials onto agricultural land provides a challenge to the producers and end-users who both have a 'duty-of-care' to ensure the method of disposal is managed in a sustainable way. Careful management means that soil and water resources are not contaminated, the agricultural production system remains stable, and land use alternatives remain availab...

Waste-to-Energy is a challenging management in developing countries. There are many different technologies to generate electricity or heat from wastes. However, reuse and recycling are first prioritized as left a fraction of waste can be used as energy recovery. The initial cost to generate electricity from solid waste incineration is prohibitively high due to its cost of advance technology and...
