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.
The use of kerosene for lighting and biomass for cooking is predominant throughout rural India. And since provision of grid electricity to rural India is still a far cry, there is an urgent need to develop alternative sources of liquid fuels for lighting and cooking. Studies at the National Agricultural …
The Hindustan Aeronautics Limited (hal) has recently initiated ecofriendly pilot projects at its Bangalore aircraft division, which will not only minimise waste, but will also help save huge sums of money. The projects include installation of a biogas plant and harvesting rainwater. The biogas plant, which is being set up …
Methan village in Sidhpur tehsil, Patan district of Gujarat saves 500 metric tonnes of fuelwood annually. They've been doing it for the last 15 years. This village is home to India's largest biogas plant, run by Silver Jubilee Biogas Producers and Distributors Cooperative Society Limited. "The biogas plant has been …
Kitchen waste turned to manure. An indigenous way to do just that has been found by Sharad Kale, a senior scientist at Mumbai-based Bhabha Atomic Research Centre (barc). Thanks to Kale, the institutes's kitchen waste is being turned into methane gas and manure. The gas thus produced is used to …
tapping renewable energy seems to be in the blood of the residents of Auroville, the little township located on the outskirts of Pondicherry. Beginning with solar energy to power their houses way back in 1970's, the community is today exporting energy efficient equipment like PV pumps, wind turbines and biogas …
a biogas plant uses cattle dung, human excreta and other organic material as raw material. The organic material has to be thoroughly mixed with an equal quantity of water. The amount of water used makes it an unviable proposition for areas with little water to spare. This is one reason …
in countries where a large number of the population still live in villages, biogas could serve as a potentially limitless fuel source for a variety of purposes. But one problem with burning biogas is the production of many polluting byproducts because of inefficient burning of the fuel. Now a team …
the Sardar Patel Renewable Energy Research Institute ( spreri) in Vallabh Vidyanagar, Gujarat, has developed a low-cost upflow anaerobic filter (uaf ) that not only treats diary effluents efficiently, but also produces biogass in substantial quantities as a byproduct, which can be used as fuel. Diary industries generate a large …
in the 1980s, a few institutional and community biogas plants were set up in some villages by cooperating centres of the Indian Council of Agricultural Research ( icar )-sponsored All India Coordinated Research Project. Islampur village in Bhopal was one of the villages selected. As in any other village, cowdung …
SINCE February 1998, four villages in Tumkur district, Karnataka, arc using oil from the Pongamia pinnata seed to fuel alternator engines in biogas plants. Though efficiency of this oil is about 20 per cent lower than that of diesel, countries such as Australia and Fiji are switching over to it …
The Centre of Science for Villages (CSV), Wardha, Maharashtra, has developed a microbiogas plant with a battery of 300 litres clay jars, which is known as Ranjan biogas plant. The biogas plant is a large clay pot churned on the potter's wheel that is utilised for storing water during summers. …
an improved biogas system has recently been developed by a Haryana-based non-governmental organisation. Compared with existing systems that produce inflammable methane by fermenting biological waste, this new system from the Social Centre for Rural Initiative and Advancement ( scria ) in Khori village, Haryana, is less expensive and can be …
most active participants engaged in the field of energy recovery from wastes agree that a rapid expansion of the acti-vity can result only if this area attains the status of an industry, fully self-sufficient and standing on its own legs. Recently a team of scientists led by P Rajabapiah from …
the national programme on biogas development ( npbd ) has been one of the most high-profile renewable energy programmes of northern India. The programme, which was introduced in 1981-82, has made significant contribution in terms of providing clean and convenient fuel and fertiliser to rural families. However, the programme has …
in our country, most of the biogas plants installed are based on cowdung. In a significant departure from the usual, the Sadar Patel Renewable Energy Research Institute, Vallabh Vidyanagar, Gujarat, has developed a biogas plant which works on kitchen waste and aquatic weeds (Rural Technology, Vol 8, No 2). Large …
BIOGAS, an asset to rural India for fuel can also provide water and manure from the plant's slurry. The biogas plant utilises animal dung and water to produce high quality gas and slurry, which can serve as an excellent manure. But since this slurry is very dilute (94-95 per cent …
UNATTRACTIVE mounds of banana peels are a common sight in rural Thailand. A project undertaken recently, aims at converting this waste into energy. Using biogas technology, the Solar Energy and Training Centre (sert) of Naresuan University in Thailand, is using this waste to procure biogas for basic rural energy requirements, …
FOR the residents of Nari, a village of 700 households in the Una district of Himachal Pradesh, underdevelopment and poverty is losing its harsh edge, thanks to the introduction of a few simple and cheap devices like water seal toilets and biogas plants. The devices are being promoted by the …
VIDYAVATI is a happy housewife today. Free cooking gas runs in her kitchen through the day. A 3-inch cement pipe, reaching down 10 feet below her kitchen and into a garbage dump brings gas to her. But her happiness could be short-lived. Recent incidents indicate that she and her friends, …
