This study assesses the potential for bioenergy production using various feedstocks such as sugarcane, oil palm, and municipal solid waste in six Caribbean small island developing states – Cuba, the Dominican Republic, Haiti, Jamaica, Trinidad and Tobago, and Guyana.
Jacquelyn Hayes highlights a method for better biogas production biogas plants don't function well when ambient temperatures are low and hence remain out of use for the greater part of the year
HOTELS and hostels in the Union Territory are saving on LPG by cooking food with bio-gas (Methane) generated from human waste. On an average, eight to 10 LPG commercial cylinders are saved per month, users say . The advantage of bio-gas is that resources required for it are generated locally …
ADATS, along with Velcan Energy, France, undertook to construct 5,500 Biogas Units for as many Coolie women under a CDM (Clean Development Mechanism) Project of the UNFCCC from October 2005. This CDM Project is well under way and even the first Verification (process by which the generation of CERs is …
The neglect of India's energy resources and the failure to adopt a scientific approach to maximise their use are unforgivable, and the simultaneous pursuit of exotic treaties is unfortunate. India faces the peril of sharp energy inadequacy today
Gas from rotting manure could fuel the future. Biogas digesters, devices that turn decomposing manure into fuel, are cost-effective, environmentally friendly and improve the health of rural people who use them. In the first rigorous study on their costs and benefits, Govindasamy Agoramoorthy of Tajen University in P'ingtung, Taiwan, and …
The biogas yield of rice straw during anaerobic digestion can be substantially increased through solid-state sodium hydroxide (NaOH) pretreatment. This study was conducted to explore the mechanisms of biogas yield enhancement.
A grass-roots movement to generate power in towns and basements is challenging the energy industry's status quo. In the late 1990s, the town of Freiamt in Germany's Black Forest decided to take the fight against global warming into its own hands. Three hundred of the town's 4,300 residents chipped in …
From both the economic and the enviromental angle, bio-gas is the ideal solution for rural households: cheap with no recurring maintenance costs and zero impact on the environment. Why hasn't it been adopted more widely? The benefits of this appropriate technology are numerous and some appear self-evident. For one, there …
The Sulabh toilets are located in five of the most congested areas of Kabul. They are an important contribution to Kabul's non-existent sanitary facilities.
City-Based Agharkar Research Institute (ARI), in association with GreenLeaf Renewable Energy Pvt Ltd, has announced the launch of 3EBT, an innovative technology to produce biogas from de-oiled castor cake, which can replace conventional fuels and be used for industrial purposes. Dr Dilip Ranade, scientist, ARI, said on Wednesday that 3EBT …
Tannery waste disposal problem leads to environmental disharmony, which makes it one of the major industrial pollution facing the country. The tannery industries, release a lot of wastes in the form of liquid (effluent) and solid (sludge). Biological sludge is one of the wastes, which has been utilized for recycling …
Koyilandi municipality, 30 km from Kozhikode, Kerala is grabbing attention as a model of excellence in civic services in a state bogged down by inefficiency, lack of direction and corruption. Koyilandi was the first town in Kerala to take the plastic-free campaign seriously with a padayatra by Municipality Chairman K …
Renewable energy pioneers from Bangladesh, China, India, Laos and Tanzania were among the winners of this year's Ashden Awards for Sustainable Development. Kerala-based ngo Biotech was adjudged the winner in the Food Security category. It bagged the 30,000 pounds (us $60,000) prize for developing biogas plants that use food waste …
This study was undertaken to find out the biogas production potential of flower waste coming out from temples. Laboratory scale digesters of 1.5 L capacity were used and fed with flower waste without and with pretreatment.
Treatment of wet organic waste such as kitchen waste has been currently one of the important environmental issues that need to be resolved. Kitchen waste has a potential to recover biogas by application of anaerobic treatment.
The overall goal of this policy is to contribute to rural poverty reduction and environmental conservation by ensuring access to clean, reliable and appropriate energy in the rural areas. In order to achieve this goal, the
The demand for petroleum products in India has been increasing at a faster rate than the increase in domestic availability, resulting in increased imports. The transport sector is the single largest consumer of petroleum products. Secondly, about 65 % of total air pollution is caused by the emissions of pollutants …
Biogas, an ecofriendly alternative to fossil fuels, has been criticised for releasing methane, a greenhouse gas that is 20-25 times worse than carbon dioxide in causing global warming. It was believed that if methane emissions exceed 5 per cent of biogas produced, then the use of fossil fuels would be …
In India, primarily cattle dung is being used as an organic substrate for the production of biogas, however, majority of biogas digesters are underfed. Thus making it essential to evaluate other available organic sources for biomethanation. Various other animal wastes like poultry droppings, sheep droppings, rabbit droppings etc have been …
