Bread4PLA: from bakery wastes to biodegradable packages

image_thumb[1]The project Bread4PLA, coordinated by AIMPLAS the Plastics Technology Centre (Valencia, Spain), has been awarded with one of the two Green Awards in the category of Environment that the European Commission has given as one of the best LIFE projects of the last 25 years
BREAD4PLA is a European project funded by the European Union LIFE+ programme whose objective is the treatment and recovery of wastes from bakery at pilot plant scale to result in new packages to be image_thumb[3]used in the same sector. Thanks to the fermentation of crusts and wastes from sliced bread and biscuits, polylactic acid (PLA) was obtained to elaborate film for new packages. This material contributes also to reduce the dependence on raw materials of fossil origin and is biodegradable, compostable and suitable to make bags and trays.
The development had the collaboration of companies such as Panrico and Grupo Siro and is especially effective to avoid the rancidity of products like cookies, where a shelf life of up to twelve months has been achieved. Besides, it has allowed to offer a high added-value application to wastes that, hitherto, were used mostly as animal feed.
In the project, other researchers have taken part from the Cereals Technology Centre (CETECE) (Spain), the Leibniz-Institut für Agrartechnik Pstdam-Bornim ATB (Germany) and the Biocomposites Centre of the Bangor University (UK).
