Galactic is to be actively involved in the ECLIPSE project launched by the European Community as part of the 7th Framework Programme. The aim of this project is to use microalgae ‘waste’ from the biodiesel process as a raw material for producing lactic acid by fermentation, which in turn will be used to produce PLA (polylactic acid). The project was chosen over several others because of its scientific excellence. At an estimated cost of 5 million EUR it will bring together 13 industrial players and research centres.

Nowadays, raw materials employed in the production of lactic acid require the use of ‘food’ crops. First-generation biomass consists of beet and cane sugar, or corn and wheat starch-based glucose. For this reason third-generation biomass, which is based on microalgae, appears to be the most interesting option. This type of biomass, which is produced in an aquatic environment, has no need for fertile land and provides a high yield per hectare. Nevertheless, it does require the addition of nutrients and a CO2 source as well as sunlight.

Galactic has already carried out research on second-generation biomass (lignocellulosic biomass) which consists in redeploying the residual non-edible parts of crops. Unfortunately, second-generation biomass is still linked to ?food? crop market dynamic and does not provide a higher yield than cane sugar for example.

‘We are very confident about this new type of fermentation. Current results show that the production cost of lactic acid would be much lower than it is right now’ says Benoît Moreau, Research Manager at Galactic. Lactic acid produced in this way would be polymerized by Futerro (a joint venture between Galactic and Total) into PLA. Plastic products manufactured using this bioplastic would be expected to have an exceptionally low carbon footprint. However, the level of greenhouse gas emissions attributed to the products themselves (PLA, algal biodiesel) will have a strong bearing on how the environmental performance of the algal-based PLA product is perceived.

 

About FP7-ECLIPSE project:

RENEWABLE ECO-FRIENDLY POLY(LACTIC ACID) NANOCOMPOSITES FROM WASTE SOURCES

ECLIPSE promotes a more sustainable and environmentally friendly approach to packaging, via the use of waste derived materials unrelated to fossil fuels and to the food chain. The main objective of ECLIPSE is to revalorize waste-derived products (algae biomass waste and plant and crustacean wastes) into novel packaging materials. The ECLIPSE approach intends to revalorize waste materials for the production of an algae-derived PLA matrix. In addition, ECLIPSE also seeks to reinforce such PLA matrix with functionalized nano-fillers extracted from non-edible banana plant, almond shell and crustacean shell wastes. This project aims at decreasing both the production costs of both poly(lactic acid) and algae biodiesel, by increasing the added value of algae waste via its revalorisation into the production of lactic acid.

ECLIPSE partners:

The ECLIPSE project relies upon the participation of several multinational companies (Algaenergy, Futerro, Banacol, Antartic and Galactic) and European and Latin American first-rate research centres including universities from Spain, Belgium, Sweden, Germany, Colombia and Chile.
