Beta Renewables Converts Cellulosic Biomass into Bioethanol

10450151_680657768650710_5470902751896477621_nBeta Renewables is Tortona, Italy based second generation ethanol producer company. It was established in 2011 as a joint venture between Biochemtex a Mossi Ghisolfi Group engineering company and the Texas Pacific Group (TPG). At the end of 2012 Novozymes became a shareholder of Beta Renewables. Beta Renewables owns the ProesaTM technology applied for the conversion of cellulosic biomass to bioethanol and many other chemical intermediates.


Proesa™ technology can use variety of agricultural wastes such as rice straw, corn cob, sugarcane bagasse as well as dedicated energy crops such as Arundo Donax known as giant reed as feedstock for bioethanol production.

Beta Renewables Proesa™ Technology

Beta renewables uses its proprietary Proesa™ technology to convert sugars present in lignocellulosic biomass into fuels and other chemicals. In the first phase of the process the biomass is subjected to high temperatures and pressures to separate the cellulose and hemicellulose from the lignin. Subsequently, the polysaccharides are treated with enzymes to release the simple sugars which in turn are fermented by yeast into ethanol. The lignin and the biogas derived from the processes are recovered and used in the boiler to generate power and heat.

Commercial Plant

Crescentino, Italy

It is the world’s first plant that started production of bioethanol from agricultural residues and energy crops at commercial scale using enzymatic conversion. The plant has the capacity to produce 75 million liters cellulosic ethanol a year. It uses wheat straw, rice straw and arundo donax, a high-yielding energy crop as feedstock. To meet the energy need of the facility extracted lignin is used at an attached power plant to generate power.

The projects deploying Proesa technology of Beta Renewables


Biochemtex’s 20 million gallon per year production capacity plant is under construction in Clinton, North Carolina, USA. The plant will use ProesaTM technology to convert energy grasses into bioethanol and is expected to start production in 2016. Biochemtex has received a conditional loan guarantee for 99 million dollars from the U.S. Department of Agriculture In 2012 to build this integrated bio-refinery.

Bioflex 1

With 82 million liters of ethanol per year production capacity this plant is among the world’s biggest cellulosic ethanol production plants. Built by GranBio it became operational in September 2014 in São Miguel dos Campos, Alagoas, Brazil. The plant uses sugarcane straw as feedstock.

Fuyang Bioproject

M&G Chemicals plan to build 200ktons/year cellulosic ethanol production capacity biorefinery in the Fuyang region of China. The Chinese firm Guozhen will supply 1M tons of wheat straw and corn stover annually to the plant. In terms of the amount of feedstock processed, the biorefinery is going to be roughly four times that of Crescentino facility of Beta Renewable in Italy. The plant will start production in 2016.


Canergy, a California based advanced biofuel company is deploying ProesaTM technology for developing a 25 million gallon a year biofuel facility in the Imperial Valley of California. The facility is expected to be operational in 2016 and will use non-food energy crops as feedstock.

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. Read more at
