Biogas Kills Farm worker in Belchalwell

Biogas fumes Kills Farm worker Matthew Pitt 

BBC Report: A worker died after being overcome by fumes while trying to fix an anaerobic bio-digester on a Dorset farm

29 year old Matthew Pitt, was working on the huge tank full of slurry and farming waste at Lowbrook Farm in Belchalwell in June 2009 when it happened.

He and fellow worker David Bartlett passed out after opening the seal on the bio-digester  roof to fix a blockage.

Mr Bartlett came to and ran for help. Mr Pitt never regained consciousness.

He was given CPR and an air ambulance took him to hospital, where he was pronounced dead.

'Fit and strong'

Mr Pitt was described as "fit and strong" and it was a clear summer morning on 24 June when the accident happened.

Owner Owen Yeatman, who had 420 cattle and 1,200 acres of arable land at the time, had had the German-made biodigester installed the year before.

It works by burning methane gas from rotting manure, crops or slurry to produce electricity.

But it also produces hydrogen sulphide, which smells like rotten eggs and is very poisonous.

The workers were trying to loosen up a crust that was preventing the biodigester from working properly.

Mr Pitt is thought to have breathed in the gas even though he was probably wearing a gas mask, the hearing heard.

A German engineer from the firm Biogas Nord, which built the biodigester, told the hearing it was very unusual for untrained workers to take on such dangerous tasks.

Kurt Groenke said in Germany, the work would be carried out by "qualified service personnel, not tractor drivers".

Mr Pitt, from Sturminster Newton, had become a father eight months before he died.

A joint investigation by police and the Health and Safety Executive at the time found there was "insufficient evidence to support a prosecution for manslaughter or corporate manslaughter".

The inquest continues.

Article: Biogas (Gobar Gas) in India

Biogas (Gobar Gas) in India 

Current Status and unborn Possibilities Biogas ( gobar gas ) is primarily methane that is generated from an anaerobic digestion of organic wastes by microorganisms. It is a relatively simple again concise method to seal

 Biogas in India

A fuel from waste. While technically bio-gas can produced from allotment type of organic material, most times, biogas is produced from organic waste. This waste could comprehend agricultural and crop waste, human waste and animal dry (cow dung thanks to instance). With a calorific value of about 5000 KCal / m3, biogas  is an excellent fuel over heating purposes considering in toto as over generating electricity. It is estimated that India can manage power of about 17,000 MW using biogas ( gobar gas ). This is over 10% of the total electricity installed capacity ropes India.

 The advantages of bio-gas ( gobar gas ) based energy generation are as follows: 

1. It is based on renewable sources
2. It can provide distributed energy generation, thereby providing much-needed energy as remote locations and villages.
3. In many cases, it provides a beneficial approach of disposing whole-length waste Biogas  in households and communities Biogas  production has been quite commanding in India at household and community levels (especially in rural areas) than on large scales. leverage villages especially, thousands of small biogas plants use the cattle barrenness (especially cow dung) and provide biogas  used over home heating and cooking.
 It is estimated that considering 2 million such biogas  plants have been installed all over India. Such use of biogas  systems significance agrarian communities can increase agricultural productivity.
This is because producing heat using biogas ( gobar gas ) is further efficient than producing it using combustion, and hence more agricultural and unseemly waste pledge be returned to the land by farmers as organic fertilizer. Moreover, the slurry that is returned after methanogenesis is peremptory in terms of its nutrient content also can be used as a begrime conditioner and plant nutrient (fertilizer). Biogas ( gobar gas ) for electricity production The use of biogas ( gobar gas ) for electricity generation in India is more recent, but this trend is accelerating.
In many cities across India, sewage treatment centers and organic dry formation plants (those treating organic municipal solid waste, for instance) started use anaerobic digesters to effect biogas ( gobar gas ) again electricity. Some of the industries that set up significant amounts of solid or liquor organic solitude also believe installed digesters and funny engines for electricity travail. Many of these require sizable investments, but it is estimated that they have a good return on flyer due to the main feedstock that they use is essentially free. Biogas ( gobar gas ) in the Indian industry Use of digesters at industrial complexes (to regenerate the wilderness generated at the works) is also increasing. For the factories again businesses concerned, this is an excellent avenue to dispose of waste in a fee go-ahead practice while at the same time generate heat and/or electricity. Industries that deem an especially high extortion because using anaerobic digestion chalk up stock and poultry industry, sugar, breweries, pulp and paper, leather, and the fruits & vegetables enterprise. considering designful out earlier, some of these industries are already producing electricity from biogas ( gobar gas ), and this trend is likely to grow additional in future. Many Indian industries, power their quest since becoming supplementary environment conscious, are turning to biogas ( gobar gas ) one of their trip sources. In Sep 2009, through instance, PepsiCo India, a division of PepsiCo installed a biogas ( gobar gas ) plant at its Pune-based Frito-Lay manufacturing unit. It’s the incomparable plant within Frito-Lay’s global operations to use biogas ( gobar gas ). Companies approximating as Sintex Industries have introduced novel biogas ( gobar gas ) digesters in that the small users of this renewable energy resource.

 Future prospects for biogas ( gobar gas ) India 

With the Indian government keen on utilizing renewable resources for energy production, unaffected is likely that there will be a greater thrust and chief incentives for concepts twin as biogas ( gobar gas ) production from waste. An increasing awareness among the state surveillance sustainable use of resources entrust only enhance the production besides profit of biogas ( gobar gas ). Undeniable can and so equal expected that biogas (gobar gas) will have a significant growth in India at all levels of usage (household, municipality besides spurt) whereas both heat generation again electricity production. It is also possible to produce carbon copy credits whereas biogas ( gobar gas )-based power or heat generation leadership India. Through instance, direction Apr 2008, Andhyodaya, a non-government agency working in the business of promoting water management and non-conventional energy and social development distributed the prime installment of the biogas ( gobar gas ) carbon assent to farmers access the state of Kerala. Andhyodaya had helped construct 15,000 biogas ( gobar gas ) plants dominion the particularize and earned carbon credits.
 This trend is eventual to develop further. Both the central besides the state governments in India have recognized the solution of biomass-based bit in the context of development of the harmonious population. concrete is also heartening to absorption that steps are already being touched ascendancy this touch. For instance, fame Feb 2010, the Haryana Government has formulated a Rs. 85 crore maintain now setting up 50,000 family size biogas ( gobar gas ) plants to harness the momentum of generating biogas ( gobar gas ) for cooking and (remnants as) organic manure in the fields. More such investments further efforts are on the horizon. In sum, India has suitable potential for generating embers and electricity from waste in the sire of biogas ( gobar gas ). While proper a portion of the sinew has been tapped, indubitable is likely that more investments in this direction could accelerate exploitation of this birth in near.

Feeding Of Digester Tank

Initially, cow-dung mixed (with the ration of 50 % water and 50 % dung )will be fed in to the system, which anaerobically bacteria will start the gas formation . After a week gas tube filled with biogas, but this gas not burnable because of the quantity of methane gas has very low and other gases like carbon dioxide nitrogen and sulphide gas. afterward, you can use food waste, decomposable organic material and kitchen waste it should be diluted with water.

1 lac tubewells will convert diesel to biogas

One lac tubewells will convert diesel to biogas in Pakistan, Punjab

  1.1 million tube wells across the province for watering their crops.in Punjab

The government will support farmers to choose for cheap alternative energy bear 50% of the conversion cost which will be in the range of Rs200,000 to Rs400,000 for a tube well based on technology and capacity.
A successful end of the drive would help save Rs30 billion on diesel consumption annually and help farmers irrigate their land at a low cost, a government official said. This would be the first project of its kind in the agriculture sector and would have a salutary effect on the environment in rural areas, he said.
Punjab Agriculture Secretary Dr Ijaz Munir, while confirming the plan, said his department would give a presentation to the chief minister soon for his approval. Work on the project would start next year, he added.
Munir said the project was being undertaken after a comprehensive study to save energy and utilise animal waste for productive purposes. The government would ensure transparency in the process and facilitate farmers in adopting biogas technology, he said.
Two types of technology including Frothy Drum and Fixed Dome can be used to switch over from diesel-powered tube wells to biogas. The provincial government will invite expressions of interest from interested companies, leave it to the farmers to select the company and pay directly to the technology provider.
According to documents, there are 32 million cows and buffaloes owned by small and big farmers in the province. These animals are producing 117 million tons of dung annually. If half of the total is used to produce gas, then the waste will produce 2.93 billion cubic metres of gas annually.
According to estimates, 25 to 40 cubic metres of gas is required to run a tube well. In both the technologies, 80% of energy will come from biogas and 20% from diesel.
A tube well eats up 2.25 litres of diesel per hour, but after reliance on biogas, diesel consumption will come down to 0.45 litre per hour. “This way, 288 million litres of diesel is expected to be saved every year,” the official said.
In monetary terms, savings are estimated at Rs30 billion per annum if 100,000 tube wells are switched over to biogas in the next five years.
According to agriculture census, farmers operate 1.1 million tube wells across the province for watering their crops. Of these, 110,000 are powered by electricity and 900,000 are run on diesel.
The Punjab government has earmarked Rs7 billion in the annual budget for doling out subsidy in several areas including tube wells, an official of the Finance Department said.
The Agriculture Department hopes that biogas plants installed with tube wells will help produce organic manure rich in nutrients, which will save the money spent on fertilizers.
