Italian start-up to produce biopolymers from sugar beet and cane residues with 95% efficiency
An Italian biotech start-up called Bio-On is entering [*Italian] the bioplastics market with a process that produces polylactic acid (PLA) based plastics from sugar beet and sugarcane residues with a claimed efficiency of 95 per cent.
PLA based bioplastics are currently produced almost exclusively from corn and grain starch. But given that prices for these feedstock keep rising because of their use in the production of ethanol, the utilization of new raw materials becomes an attractive proposal. The production of sugar crops - both cane and beets - on the contrary is outstripping demand. Both Brazil and India delivered record crops, and in the EU too sugar prices have declined.
Bio-On (a name chosen as the opposite of 'petroleum-off') has developed a series of patented processes that ferment waste and byproducts from beet and cane processing into lactic acid, filtrates and polymers useable for the production of a range of fully biodegradable plastics. PLA is biodegradable in soil, compost or water, and the degradation products of PLA are non-toxic to the environment. PLA has comparable mechanical properties to petroleum-based plastics.
According to Marco Astorri, co-founder of Bio-On, a bio-cascading strategy results in a residue-to-product efficiency of 95 per cent. In other words: waste streams become valuable resources that can be converted almost in their entirety in a useful product. Sugar beet pulp, one of the prime feedstocks, is usually used as low value animal feed or disposed of at additional cost. Likewise, bagasse and mollases from sugarcane have a relatively low value and are abundantly available.
Moreover, Bio-On's production process would reduce energy costs and as it is based on a multi-feedstock strategy, costs for raw materials would be substantially lower than those for traditional PLA production.
A first range of products to be developed by Bio-On are a range of biodegradable plastics with natural flame retardants to be used for automotive applications:
energy :: sustainability :: biomass :: bioenergy :: biofuels :: sugar :: waste :: bioplastics :: polylactic acid :: bioeconomy
The planned location of the production plant is quite significant: 'Plastic Valley' in Bologna, the region with a long tradition of developing innovative plastics, with some leading research organisations working on bioproducts. There, Bio-On is creating relations with universities and scientists, and aims to have a production facility ready by 2009. Output would be 10,000 tons.
Between 2 and 3 million euros have so far been invested in research and development, whereas the full scale production plant would add another €10 million. Contrary to some other bioplastic manufacturers, Bio-On will be financed entirely by the private sector. The founders are looking for partners to licence the technology for production abroad.
Bioplastics face a bright future in Italy. This year a series of laws and policies came into effect that aim to phase out the use of petroleum based plastic bags and other products entirely by 2010.
Sugar crops have recently gained attention as feedstocks for a range of biobased plastics. Recently the Dow Chemical Company, the world's largest producer of polyethylene, and Crystalsev, one of Brazil's largest ethanol players announced plans for a world-scale facility to manufacture polyethylene from sugar cane (earlier post). Braskem too, the leading company in Latin America's thermoplastic resins segment and Brazil's second largest privately owned industrial company, recently produced polyethylene, this time made from sugarcane ethanol (more here).
The University of Queensland (UQ) and the Korea Advanced Institute of Science and Technology (KAIST) have teamed up to develop and patent technologies to convert sugar cane into bioplastics and green chemicals (previous post); finally, leading bioplastics producer Metabolix announced a collaboration with the Cooperative Research Centre for Sugar Industry Innovation through Biotechnology, an alliance of Australia's sugarcane biotechnology research organizations, to develop natural plastics from sugarcane.
Add the fact that recently Syngenta introduced a high yielding sugar beet developed specifically for the tropics, and the prospects for the bioeconomy in the Global South look ever more promising. An overview of bioplastics and biopolymers being developed in developing countries can be found here.
