ANDRITZ Technology for Fiberight’s Municipal Waste to Biofuel Plant in Iowa
 Graz, Austria based technology manufacturer, Group ANDRITZ, is to supply equipment, engineering, and field services for Fiberight’s cellulosic ethanol plant in Blairstown, Iowa.

The manufacturer explained that its technology will be used for continuous pre-treatment of municipal solid waste feedstock which will then be converted into cellulosic ethanol using Fiberight’s existing fermentation and distillation processes.

The company added that its technology utilses a unique steam heating concept to continuously preheat and cook the feedstock at elevated temperatures, producing an average of 200 bdmt/d (bone dry metric tonnes/day) of pretreated material.

Catonsville, Maryland based Fiberight is a privately held clean technology company focused on transforming post-recycled municipal solid wastes and other organic feedstock into next generation renewable biofuels, with cellulosic ethanol as the core product.

According to Fiberight it has successfully developed a biomass conversion process that produces commercially viable quantities of renewable biofuel and other valuable biochemicals from municipal solid waste.

The company said that its technology efficiently fractionates the organic components of MSW such as contaminated paper, food wastes, yard discards and other degradeables for the production of cellulose and hemicellulose into fuel grade ethanol and other sugar platform biochemicals using enzymatic hydrolysis and fermentation.

The process is also said to extract a plastic fraction and methane which can be used to generate enough heat and power to cover the facility’s energy requirements.

According to Fiberight, its proprietary extraction, pulping and digestion processes has the potential to unlock over 5 billion gallons (19 billion litres) of renewable biofuel contained in the 175 million tons (159 million tonnes) of non-recyclable Municipal Solid Waste (MSW) generated each year in the U.S.

The blairstown ethanol facility was originally designed and built to produce ethanol from corn feedstocks, but was purchased by Fiberight back in 2009 for conversion to process wastes.

According to ANDRITZ, start-up is planned for the first quarter of 2015.

Fiberight is also in negotiations with the city of Iowa City to set up a waste sorting facility at the Iowa City Landfill, from where it will take organic material and transport it to the Blairstown ethanol plant.

Additionally, the company is planning to build a $20 million waste sorting and pulping center in Marion that has dubbed the Marion Waste Revitalization Center.

In addition, $25 million loan guarantee from the U.S. Department of Agriculture, a $2.9 million grant from the Iowa Power Fund and more than $20 million in private investment.

Following a deal with the City of Marion, company has created a deal with Fiberight in which the company will build a Materials Resource Recovery Facility to turn the city’s trash into fuel.
