The aim of this document is to provide an overview of the possibilities for resource recovery from sanitation and provide guidance on treatment processes to achieve safe products for reuse. The focus of this document is on resource recovery from the organic wastes managed in sanitation systems and, to a lesser extent, on the recovery of water and energy generation. Resource recovery sanitation …
Since 1900's, anaerobic biogas digester had been applied successfully in Asian countries like India, Nepal and China, treating cow manure, pig excreta, organic waste or a combination of them, providing not only biogas, which is used as source of energy, but also slurry used as soil conditioner.
During last 20 years in India, different government and private institutions promoted the use of …
The Policy Guidance Manual on Wastewater Management with a special emphasis on Decentralised Wastewater Treatment Systems (DEWATS) highlights adequate policy and sustainable practices from the South-East Asia (SEA) region and worldwide. The primary objectives of the Policy Guidance Manual on DEWATS for SEA are three-fold:
(a) to guide national and local policy-makers and experts of SEA in …
This is the recording of an online expert chat using Adobe Connect hosted by Stockholm Environment Institute (Arno Rosemarin) on 1 July 2013. It is part of a larger grant that SEI received in November 2012 from the Bill & Melinda Gates Foundation. The topic of this expert chat was "Research projects involving anaerobic processes with biogas generation", and it was the first expert chat in a …
By mid-century, the global urban population is projected to increase by 2.4 billion people with 60% of growth expected to take place in cites of sub-Saharan Africa (SSA) and South Asia (SA) (UN-DESA, 2015). These regions have some of the lowest rates of urban sanitation coverage and modern fuel access, with only 41% and 67% estimated to have access to improved sanitation and 19% and 55% estimated …
Providing adequate water supply and sanitation, particularly in urban areas, is a challenging task for governments throughout the world. This task is made even more difficult due to predicted dramatic global changes. Population growth, urbanisation, increasing industrialisation, climate change and a steep increase in water consumption are putting pressure on urban water resources. In order to …
Decentralised Wastewater Treatment Systems (DEWATS) such as disseminated by the Bremen Overseas Research and Development Association (BORDA) are increasingly being recognized by decision makers across the world as an option for service delivery in densely populated low-income areas. However, little practical experience has been gathered methodologically on basic engineering and performance …
