Cogeneration & On-site Power Production tells us that the African country of Rwanda is using human waste to generate electricity for its prisons.
CleanBiz Asia reports that processed waste oil refined from leftover Chinese cooking oil is en route to the Netherlands for further treatment into aviation fuel for KLM. The ‘non-edible oil’ will become bio-diesel oil after a second process to take place in the Netherlands. The Chinese oil was produced by combining waste oil and fat, including “gutter oil,” or discarded cooking oil.
From OILPRICE we learn that there is going to be a waste-to-energy boom. Pike Research predicts the global market for thermal and biological waste-to-energy technologies is set to reach at least $6.2 billion in 2012 and grow to $29.2 billion by 2022. In an attempt to reduce landfill use, and solve our looming energy problems, waste-to-energy processes will become more and more popular in most countries. Pike Research predicts that by 2022 waste-to-energy systems will convert more than 261 million tonnes of waste each year into an estimated 283 terawatt-hours of electricity. Energy and Environmental Management added to this story and discussed the concerns of opponents in energy-from-waste set for expansion. Opponents claim that incineration of waste to produce electricity reduces the demand for recyclable materials and is less efficient in the long run. In 2011 over 800 thermal waste-from-energy plants currently operated in nearly 40 countries around the world. Although combustion technologies dominate the market, anaerobic digestion and advanced thermal treatment technology such as pyrolysis are expected to pick up as diminishing landfill capacity improves the economics.
Sydney, Australia is building a low carbon energy network using waste heat in its central business district according to The Australian. A tri-generation network could save $1.6 billion in grid upgrade costs over the next two decades by supplying four city precincts with low-carbon electricity, heating and air-conditioning. Tri-generation uses natural gas-powered engines to produce electricity on-site and captures heat waste to be re-used for heating or cooling water. It is part of the city’s broader plan to provide 70% of the city’s electricity requirements using the tri-generation network by 2030.
A 68 MW multi-fuel power facility is being built in West Yorkshire, England says Waste Management World. The facility, to be completed by 2015, is being built at SSE’s Ferrybridge power station. The facility will use a range of fuel sources, including biomass, waste-derived fuels and waste wood, to generate electricity with the fuels predominantly from the Yorkshire region. The facility will have a capacity to handle some 740,000 tonnes of mixed fuel each year and the electricity will go to the National Grid.
TheBioenergySite discusses the growing use of anaerobic digesters on farms in the northeast US which convert cow and pig manure into ethane (a biogas) which can be used to generate electricity. One Pennsylvania farmer tells how his 500 cows and his digester enable hin to heat his home and milk house, make bedding for his cows, fertilise his fields, dry his corn and pasteurise the milk he feeds his calves. In addition, he provides enough electricity for 100 homes in the area. The Central Vermont Public Service Corp. began its “cow power” program to turn manure into energy seven years ago. It now has 10 farms providing power to 3,300 households and 200 businesses with electricity. Eight more farms will come online in the next three or four months.
Waste Management World reveals that the Australian state, Western Australia, is undertaking a comprehensive waste-to-energy technology review. The purpose of the review is to examine different technologies used in Europe, the USA, Japan and Australia in order to give the state government the most up-to-date information on the waste-to-energy business. The study will look at a range of operating facilities around the world using a variety of technologies including gasification and incineration and examine the way these facilities are designed, how they operate, their emissions, and the regulatory framework under which they operate
ABS-CBNnews notes that the first Philippines biomass gasification plant has opened. The facility is located in Dinalungan, Aurora and will provide electricity to rural areas at less cost than diesel. Biogas gasification is a renewable energy source as it uses forest and agricultural waste for fuel. This gasifier will use wood, coconut fronds, coconut shell, biomass briquettes made from rice straw, rice and coconut husks, corn cobs and dried grasses. There are more than 150 off-grid rural areas in the country which rely on increasingly expensive diesel for electricity. See also the press release.
Ironbridge Power Station in Shropshire, England is planning to substitute wood pellets for coal reports the BBC. The wood pellets from North America would replace coal from Russia to generate electricity. In the past the 1 GW facility has burned cocoa husks.
Cogeneration & On-site Power Production says that woodchips are going to power the first supermarket in the UK. Waitrose’s East Cowes store on the Isle of Wight has become the first UK supermarket to receive most of its heating, cooling and electric power from local woodchips. In future there will be the capability to local homes and community buildings.
Waste-to-energy company Ameresco is to build a new facility in the city of Philadelphia as part of the Northeast Water Pollution Control Plant Biogas Project, which will use waste biogas to generate electricity and thermal energy for on site use. The biogas is generated from waste water and is currently being flared. Bioenergy Insight says the facility will generate 5.6 MW of electricity, reducing the plant’s energy costs by more than $12 million during the first 16 years of the contract.
Waste Management World posts that a waste plastic to fuel facility is to be constructed in Bristol, England. Liquefaction, pyrolysis and distillation will be used produce up to 19,000 litres of syngas fuel from 20 tonnes of plastics. The syngas not only creates biofuel, it is also used to heat the pyrolysis chambers.
The city of Ashville, North Carolina in the US is generating electricity from its landfill reports the Citizen-Times. The system is producing enough electricity to power 1,100 homes. Prior to installing the 1.4 MW generator, the city burned the methane produced naturally at the landfill. Now it is earning $500,000 a year selling the electricity. The city is considering putting a second generator on-line in six years as the landfill grows.
