THE FIRST BIODEGRADABLE AND COMPOSTABLE PACKAGING FOR THE CEMENT INDUSTRY IS LAUNCHED

 
 The very first biodegradable and compostable cement bag - BioSac by Ciments Calcia – has been launched into the French market so that the building industry can benefit from a 100% environmentally-friendly solution to the management of wastes on building sites.

In France alone, the bagged cement market generated nearly 35,000 tonnes of packaging waste in 2008 – and this is currently treated as ordinary waste and disposed of in class II sites or incinerated. Biosac, is the first biodegradable and compostable bag - developed collaboratively by Limagrain Céréales Ingrédients (LCI) with the Barbier, Mondi and Ciments Calcia groups.

Nathalie Gorce, Marketing Manager for biolice at LCI, explains: "Conventional cement bags consist of a double layer of kraft-type paper for strength and a polyethylene (PE) 'free film' for product conservation. However, this combination of different types of materials prevents the immediate recovery of the packaging. The innovative nature of BioSac comes from the composition of its 'free film', which now uses LCI's biolice to give a technically innovative solution to the problems of managing this type of packaging.

"Biolice is made using a process unique on the bioplastics market, using whole cereal grains from a number of specific Limagrain maize varieties. The product's innovation lies in the combination of cereal fractions with a biodegradable polymer."

Thanks to its exclusive composition, BioSac conforms to the EN 13 432 standard, concerning packaging that is recoverable by biodegradation and composting. According to the EN 13 432 standard, compostability is verified according to four criteria:

Biodegradation: this refers to degradation caused by the actions of specific enzymes leading to significant changes in chemical composition (with the release of water, CO2, methane and heat). The minimum biodegradability threshold in composting centres must be 90% within a maximum period of 6 months.

Fragmentation: this involves the physical decomposition of materials into small fragments.

Heavy metals: checks are performed to test for the presence of certain metals such as mercury, lead, cadmium, etc.

Ecotoxicity: this consists of confirming the absence of harmful effects on the growth of plants.

Biosac has also been awarded the OK Compost Label (Accreditation number S145). In short, this new generation packaging has passed all of the tests with flying colours, guaranteeing the decomposition of 96.3% of its materials in only 12 weeks under industrial composting conditions.

Nathalie Gorce concludes: "This latest application of LCI's biolice is a result of our long-term and continuing research programme into bioplastics. Biolice was introduced to the market in 2005 as a 100% biodegradable and 100% compostable bioplastic, and now we see the various grades in an increasing number of applications. These include refuse, shopping and green waste bags; netting and packing films; and thermoformed disposable products for packaging as well as containers and cups, and the manufacture of disposable and single use food trays."
