Fulcrum BioEnergy: Municipal Solid Waste to Renewable Fuel

Fulcrum BioEnergy is California, United States based municipal solid waste (MSW) to renewable fuel producer company. With the help of its thermochemical process Fulcrum Bioenergy  converts the organic waste of the garbage into clean renewable fuel. As an approximation the garbage generated by more than one million people serve as a feedstock for 30 million gallons renewable fuels per year. Being drop-in replacement Fulcrum’s fuel does not require changes in the existing fuel infrastructure.

Feedstock

The process developed by Fulcrum Bioenergy utilizes organic part of the MSW. According to the producer the benefits of using  MSW as biofuel feedstock is the fact that it does not have to be grown and has no other uses. Its procurement is also less tricky. In order to secure large volumes of MSW, Fulcrum BioEnergy has made long-term agreements with two of the largest waste services of North America ‘Waste Management’ and ‘Waste Connections’.

Fulcrum BioEnergy’s ConversionTechnology

Fulcrum BioEnergy has developed a technology platform for converting MSW to transportation fuels via thermochemical route. The process is ready for deployment.  The first municipal solid waste to renewable fuels plant of the company is under construction. The various steps involve in the process are:

Feedstock Processing
The contracted waste services companies will provide the MSW to the Fulcrum’s feedstock processing facility. Here it will be processed and recyclable materials of commercial importance and inorganic waste will be extracted from it. The organic material recovered from the MSW will be supplied to the biorefinery where it will first be shredded and then fed into the gasification system.

Gasification System
The second step consists of the heating of the fed MSW in the gasification system. This results in the immediate conversion of MSW to syngas. In the next step the syngas is cleaned by a venturi scrubber by capturing and removing any entrained particulate matter. Syngas is then cooled in a packed gas cooler scrubber. The cleaned syngas is further processed through an amine system to capture and remove sulfur and carbon dioxide. The end syngas product is very clean and is sulfur free.

Fischer-Tropsch (FT) Process
Purified syngas reacts with Fulcrum’s proprietary catalyst to form intermediate heavy, medium and light fractions of the FT Liquids products. The light fraction of the FT liquid is commonly Naphtha which is recycled in the partial oxidation unit along with the remaining tail gas to get converted into hydrogen and carbon monoxide.

Fuel Upgrading
In the last step, the heavy and medium FT liquids are upgraded through hydrotreating, hydrocracking and hydroisomerization into jet fuel.

Facilities

Sierra BioFuels Plant, McCarran, Storey County, Nevada

The first municipal solid waste to renewable fuels plant of Fulcrum BioEnergy is expected to become United States’ first fully operational, commercial-scale MSW to renewable fuels production plants. It is under construction. The Sierra BioFuels Plant will be comprised of a feedstock processing facility and a biorefinery that will convert approximately 200,000 tons of prepared MSW feedstock into more than 10 million gallons of jet fuel or diesel annually.

Fulcrum BioEnergy plans to develop a number of renewable fuel production facilities with production capacity as much as 300 million gallons across North America by the end of 2020.

Karnataka to get $50 million dollars for biofuel

In India the Karnataka States’ Biofuel Development Programme  is set to get a boost in the form of  $50 million dollars from International Fund for Agriculture Development (IFAD). The loan can be utilized in various activities such as plantation of biofuel crops and production. Biofuel Development Board of Karnataka has been active in promoting biofuels and  has established biofuel information and demonstration centres with about 100 l per day capacity in each district. These centres are being scaled up to 150-200 l capacity. The Board also owns a 500 litre biodiesel production plant at Hatti Gold Mines. The loan conditions include 1% interest with a 50-year repayment period.

China’s first commercial flight powered with biofuel was successfully completed

China's first commercial flight powered with biofuel was successfully completed between Shanghai and Beijing. The privately owned Hainan Airlines flight used biofuel made up from used cooking oil collected from the restaurants. The biofuel was supplied by China National Aviation fuel company and energy giant Sinopec. It was a Boeing 737 plane which used 50% biofuel blended in conventional jet fuel and carried more than 100 passengers to their destination.

India achieved only 1.4% ethanol blending this fiscal year

Problems between sugar mill owners and oil marketing companies have resulted in only 1.4% ethanol blending through february this fiscal year which is way less than the blending target of 5% and lesser than the last year's achieved blending level of 2%.The National Policy on Biofuels of India identifies the sugar cane molasses as the feedstock suitable under Indian conditions for ethanol production for blending purpose and that makes the sugarcane mills as the biggest suppliers of bioethanol. The high state-level levies on the biofuel and the requirement of obtaining permits from authorities have been sited as the major impediments for producing bioethanol by Sugar Mills. The government has set the selling price of ethanol for sugar mills @  Rs. 48.50/litre  if the depo of the oil marketing company is within 100 km from distillery and  @49.50/ litre  if the depo is beyond 300 km. The producers claim that the long distance transportation also reduces their margin. India needs approximately 115 crore litres of ethanol to meet the 5% target.
