US Biofuel plant to convert solid waste to ethanol

USDA to provide $105M loan guarantee to Fulcrum Sierra Biofuels; municipal solid waste to ethanol

6 August 2012

The US Department of Agriculture (USDA) announced a $105-million loan guarantee to Fulcrum Sierra BioFuels, LLC to finance development of a facility to convert municipal solid waste into advanced biofuels. With the loan guarantee finalized, the company will secure bank financing, which when combined with private equity capital provided by Fulcrum, will fully fund construction of the municipal solid waste to renewable transportation fuel facility.

The Sierra BioFuels Plant will be located approximately 20 miles east of Reno, Nevada in Storey County. The plant will produce 10 million gallons of ethanol annually as well as renewable energy to be used at the plant utilizing processed municipal solid waste as a feedstock. Fulcrum Sierra uses a two-part thermo-chemical process:

  1. Gasification converts the MSW into a synthesis gas, or syngas. Heat released in the gasification process is recovered to create steam for use in the plant.
  2. The syngas is catalytically converted into ethanol using our proprietary alcohol synthesis process.

USDA, through its Rural Development Biorefinery Assistance Program (Section 9003 of the 2008 Farm Bill), approved an 80% loan guarantee to finance the project, with a conditional commitment that Fulcrum Sierra BioFuels, LLC must meet before loan closing.

The announcement is part of a larger USDA effort to produce advanced biofuels in every region of the country. USDA has funded 7 additional biorefineries that are using feedstocks like agriculture residue, woody biomass, municipal solid waste, and algae in states from Florida and Michigan to New Mexico. USDA is also investing in research by coordinating with five regional research centers to work on the science necessary to ensure profitable biofuels can be produced from a diverse range of feedstocks.


Family Day August 1st at the Green Back Yard!

Join Peterborough’s  Award winning Green Family of the Year 2012, for a Family Day at the Green Back Yard – we’ll be making Fondue as its also Swiss National Day – so bring some cheese and bread!  Where: The Green Back Yard, Oundle Road, Peterborough  When: Weds 1st August 2012 from 11am



Friends of Peterborough’s Green Back Yard Project launched the campaign to save the site today.

The Green Back Yard project was set up on a long-disused allotment space in central Peterborough, historically what remained of the ancient Rams Fair Meadow. The site is now under threat of residential building development as part of the City Council’s ongoing plans and the tenure of the site is now uncertain.

The award winning project has been developed under the capable leadership of father and daughter team Renny & Sophie Antonelli. The previously disused site has been transformed into a thriving urban garden and is a centre for a diverse range of community activities from arts and music events, green skills training courses to martial arts  – mostly conducted on a voluntary basis  by many hundreds of local people.   The award winning site is a unique and precious community asset which the people of Peterborough need to remain in its current location.

Visit the campaign’s facebook  page  or download a post card here to print and send to the council to show your support for the Green Back Yard.

Film about The Green Back Yard Peterborough

A film made recently by Daryl Mulvihill about the Green Back Yard has been released online

The site is currently leased from Peterborough City Council, who now have plans to redevelop the land, resulting in the loss of a unique and valuable community asset right in the heart of the UK’s Environment Capital.

Bio-fuel project car at the Peterborough Green Festival 2012

Pyrois Biofuel Project Car
1959 Chevrolet Impala Biofuel Car
The car attracted plenty of interest…
Some gave it more attention than others…!

The Pyrois Technologies Project car – a unique classic 1959 Chevrolet Impala that is being modified to run on bio-fuels was unveiled at the launch of the Peterborough Green Festival as part of the Peterborough In Transition initiative, raising awareness of peak oil and climate change and the need to find alternative renewable and sustainable fuels for the future.

The car has been upgraded to run on a Biobutanol/gasoline blend and is in the process of being modified to allow use of clean-burning Bioethanol fuel.

Bob Hodgson, of Pyrois Tech, said “We were thrilled to be part of the Green Festival Launch, and were especially encouraged by the positive comments we had from the general public. It has helped raise the profile of the environmental issues behind climate change and peak oil and some of the solutions, which we are actively trying to solve here in Peterborough, the UK’s Environment Capital. We will also be displaying the car at the Peterborough In Transition Launch Celebration which is being held at the Green Back Yard , Peterborough on Saturday 9th June.”
