Return on Investment Case Study // Accelerating Solar Water Pump Sales in Kenya

This Return on Investment case study by Winrock International shows an increase in gross profits of up to 186% within one to two crop seasons after purchase of a solar water pump (SWP) for smallholder farmers in Kenya. Between August 2015 and December 2016 Winrock demonstrated SWPs to more than 16,000 of such smallholder farmers and found that despite strong demand, the lack of smallholder credit options for solar irrigation is a key obstacle preventing SWP sales from increasing rapidly;...

Case Study // Waste Management in Danang, Vietnam

By Martin Schaub and Jérémie Bertrand. This case study analyses the feasibility of viable solutions for an environmentally friendly and future-proof disposal of approximately 1,000 tonnes per day of municipal waste at Da Nang, the fourth largest city in Vietnam and largest city in Central Vietnam. The authors show that a technology apt to meet the specific waste composition of the reagion could replace the energy-inefficient and uneconomical incineration treatment with a Nexus approach-based...

Case Study // Waste Management in Tanjung Pinang, Indonesia

By Martin Schaub and Jérémie Bertrand. This case study presents a concept for the implementation of an Urban Nexus-approach based waste management system in the city of Tanjung Pinang, Indonesia. Tanjung Pinang is the capital and second largest city of the Indonesian Riau Islands province. The 250,000 inhabitants produce 160 tons of municipal solid waste (MSW) daily of which apparently only half is collected and disposed at Ganet Landfill.
