This report outlines the findings of a study carried out in and around the city of Nairobi, Kenya by ENVILEAD. The study was carried out between the months of January and March 2005, about the patterns of practice that are likely to release persistent organic pollutants (POPs) into the environment as part of the International POPs Elimination Project (IPEP’s) initiatives. The focus of the study was the practice of medical and municipal waste burning, which research has shown to be a potential source of unintentional POPs (UPOPs). The study’s objective was to investigate the anatomy of this practice, identify the key issues involved and make recommendations for the way forward.

These approaches differ by the origin of the used matter (wastewater, sludge liquor, fermented or non-fermented sludge ash) and the process (precipitation, wet chemical extraction, and thermal treatment).

It is a high-speed process that uses the force from rapid rotation of a cylindrical bowl to separate wastewater solids from liquid.

It shows how public/community participation can support small-scale construction work while ensuring checks on quality and price of construction, including examples.

The generated product, an “aluminium phosphate”, is a valuable raw material for the phosphorus industry. After alkaline treatment of the “aluminium phosphate”, it is possible to precipitate phosphorus as calcium phosphate (advanced SEPHOS Process). Following acidic elution of the ash, nano-filtration can also be used to separate phosphorus.

The indiscriminate and erratic handling and disposal of waste within health-care facilities is now widely recognized as a source of avoidable infection, and is synonymous with public perception of poor standards of health care. Water pollution and inadequate wastewater treatment pose important risks to health.

The site includes documents, workshop inputs and presentations with best practice examples of sustainable sanitation options in emergency and reconstruction situations.
This document summarises the discussion and outcomes of an expert workshop in 2009, identifying useful ideas that can improve sanitation practices in terms of sustainability but are still suitable for emergency situations. It includes inputs from various experts from the sector.

It shall help the user to find a tailored solution suitable for the specific context that the sanitation system will be placed in. The tool exists as a print and digital version.
A portable toilet appropriate for disaster response is presented in this report. The urine is diverted and the feces undergo a lactofermentation process. Biochar is added also to the feces to eliminate odor and facilitate the reuse of the excreta as a soil additive. The design, costs, logistics and expected challenges are discussed.
