The Sanitation Workers Knowledge + Learning Hub is the best source for all current news, trends, articles and updates on sanitation workers rights around the world.
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 …
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 …
It is hoped that the hand book will guide Biogas Construction Enterprises (BCEs) in developing appropriate business and marketing plans in order to increase the revenue as well as guiding BCEs in management and operational
issues. The Hand Book will guide BCEs on key issues of financial procedures and internal controls. The Hand Book will also serve as a guide for any small to medium size …
SNV/BSP had organized a biogas training course from 17 to 20 May 2000 for the trainers of Junior Biogas Technicians (JBT) of the Institute of Engineering (IOE), Pokhara with the participation of 16 trainees having engineering background (Engineers and Overseers). The training was rated very useful. Subsequently, with support from SNV/BSP, Centre of Energy Studies (CES) of the Institute of …
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 …
The book includes detailed descriptions of all the process steps to be followed during the production of biogas, from the preparation of the suitable substrate to the use of biogas, the end product. Each individual stage is assessed and discussed in depth, taking the different aspects like application and potential into account. Biological, chemical, and engineering processes are detailed in the …
Toilet linked biogas plants have been implemented at some scale in different villages in some districts of Gujarat by WASTE, Netherlands and FINISH Society, India. In an earlier study, the performance of such toilet linked biogas plants was compared to non- toilet linked biogas plants. The economic benefits of application of toilet linked biogas plant slurry on agricultural lands for different …
Biogas from cow dung with or without toilet linkage is in practice for over 3 decades in India. It
is supported by the Ministry of New & Renewable Energy, Government of India and State
Governments. However, the toilet linked biogas plant programme could not get required momentum, even
though it has several advantages.
To overcome the problem, the additional economic importance / advantages 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 library entry contains key documents involved in the implementation of the UBSUP programme, from the social marketing for improved toilet at household level to the construction and operation of the sanitation infrastructures (toilet and Decentralised Treatment Facility). Note that more documents are available on the SafiSan toolkit located in the WSTF website, see link below.
As an …
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 …
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 …
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 …
