Anaerobic co-digestion of farm-based manure, food waste, are there benefits vs. landfilling?
Based on a comprehensive life cycle analysis comparing the environmental impacts and economic outcomes for managing manure and food waste produced on a dairy farm, researchers found that anaerobic co-digestion ...
Algae discovery means pig waste could provide more for farms
The Cooperative Research Centre for High Integrity Australian Pork (Pork CRC) has invested $300,000 with the Algae Research and Development Centre at Murdoch University to investigate the proposals, which ...
Research center turns yogurt waste into new products
With exploding consumer demand for Greek yogurt, production is up. That's great for food companies' bottom lines, but it also leaves them dealing with a lot more acid whey, a problematic byproduct of the ...
Waste-biogas is at least ten times more effective than crop-biogas at reducing greenhouse gas emissions
In a paper just released in the leading bioenergy journal Global Change Biology Bioenergy, researchers from Bangor University and the Thünen Institute in Germany conclude that crop-biogas and liquid biofuels are at best i ...
Sustainable green alternatives to fertilisers could boost food and energy security
Lancaster University scientists are leading research looking at formulating sustainable fertilisers from renewable energy waste.
Study reveals important environmental trade-offs for biogas production on dairy farms
There is increasing interest in on-farm anaerobic digestion (AD) in the UK to manage animal manures and food waste, and to generate renewable electricity and heat via combustion of biogas.
U.K. grocery store to power itself on biogas generated from its own food waste
Water treatment could be carbon neutral
Carbon dioxide released by some wastewater treatment plants could be recycled at the same time as enhancing the production of renewable energy in the form of natural gas, say scientists.
Anaerobic treatment of wastewater is a step towards sustainable energy
Until recently, most of the world's energy supplies have come from coal, oil and gas. Scarcity of natural resources, surging energy prices and global warming had focused attention on renewable energy, and consequently, alternative ...
More profitable biogas production by optimization of anaerobic waste digestion
VTT Technological Research Centre of Finland (VTT) coordinates a new European project, which focuses on studying anaerobic digestion (AD) of organic waste and developing its control. AD process can be optimized to produce ...
Biogas from animal waste in need of maturity
Biogas-based energy could solve both the environmental concern of agricultural waste and reduce dependency of fossil fuels, particularly in Eastern Europe, albeit at a steep production cost.
Regions could use food waste for fuel
Murdoch University researchers are touting biogas from small-scale food waste digesters as a source of renewable energy for rural and regional communities.
Studies show biosolids can boost soil phosphorus levels for years
Treated wastewater solids called biosolids are sometimes used by farmers to boost soil nutrient levels. Now research by a U.S. Department of Agriculture (USDA) scientist provides new information about how ...
Researcher's waste-to-energy technology moves from the lab to the marketplace
(Phys.org) -- Technology invented by a University of California, Davis, researcher that converts solid waste into renewable energy is debuting today as the first commercially available, high-solid anaerobic ...
