  • Link to the article: http://www.greenpatentblog.com/2012/04/13/enough-noxious-gases-biogas-electric-cuts-emissions-from-anaerobic-digesters/

    A 'greener' technology of electricity generation is bound to attract investors and subsidizers alike. Biogas and Electric, a technology development company oriented towards biopower research, has taken a step forward in that direction by finding a way of reducing NOx emissions from biogas engine exhaust.

    The principle involves wet-scrubbing of the exhaust by the reactor refuse, during which a significant portion of NOx is removed.

      "The technology is an add-on solution to the biogas engine. The add-on puts the biogas engine exhaust in contact with the liquid waste stream from the anaerobic digester. “Mike determined that certain chemicals are endogenous to the waste stream, such as ammonia, which can scrub the NOx out of the exhaust stream,” stated Burns." Interesting idea indeed... Btw, the waste stream is normally used as a nutrient for agricultural purposes...not sure if the high NOx levels in it could make it less usable...

  • Direct current plasma arc technology has been finally signed for use by Peterborough Renewable Energy (PREL) to deal with Air Pollution Control (APC) residues created onside at EnergyPark Peterborough.

    The final agreement was signed this week between PREL and plasma arc supplier Tetronics but the overall project was granted consent by the Department for Energy and Climate Change back in November 2009. It was at the end of last year when the two companies started the partnership (see Waste Management World story).

    A combination of technologies will be used at the park, including a biomass from waste gasification power station, after which APC residues will be collected and transferred to the co-located Tetronics' plasma unit.

  • Plasma gasification is heralded to be biggest thing that happened to the waste to energy field. But I also heard that this process requires significant amount of energy for its operations...Any idea what % of energy generated by a plasma gasifier is consumed for auxiliary power?

      It is an attempt. It will be successful, if the plasma torch will be bigger and eats less energy. E.g. cool small plasma generator eats 6-12 kW and produces ~0.05 cbm/min of gas mixture (n.c.) ~ 200 CC.Apologists of this method do not like speak about it. But again, this is the best method to destroy all contaminants and turn them to CO2, nitrogen, sulphur, chlorine, etc. oxides and steam.

  • The threat of paying millions in penalties each year means Britain urgently needs a new infrastructure to deal with its waste, according to a new report to be launched in Parliament on Tuesday.

    To deal with our waste efficiently an investment of £8bn will be needed by 2020, rising to £15bn by 2030, the Associate Parliamentary Sustainable Resource Group said.

    The EU can impose unspecified fines for failure to meet landfill targets, which require Britain to halve the amount of biodegradable municipal waste sent to landfill by 2013, compared with 1995 levels. By 2020, the target increases to 65pc.

  • Prior to the implementation of the solid waste management program in 2001, Barangay Bagumbuhay had a very serious problem in managing their waste. The garbage trucks did not regularly pick up the garbage aside from its difficulty in penetrating the too narrow streets to collect household wastes. Only four main roads out of 23 streets in the barangay are enjoying proper garbage collection, creating garbage piles filling the missed streets that produce stinky smell all over the community.

    See how the community tackled it, from here - http://www.alagad.com.ph/special-cross-sectoral-concerns/73-solid-waste-management-best-practices/430-use-of-low-cost-and-local-technology-in-solid-waste-management-the-barangay-bagumbuhay-experience.html

  • The award recognizes excellence in the management of integrated solid waste management systems — a system that uses complementary facilities and programs to manage specific components of the municipal solid waste stream.

    Marion County was recognised for its many innovative and unique programs, including: the collection of paints, anti-freeze, batteries, and cooking oil at the curb for recycling.
