Corporate Communications: Which subjects in terms of bioplastics are currently discussed in public?
1. How useful is it to suddenly cultivate raw materials for packaging instead of food in a field?
2. How many cultivated acres are needed for the production of bioplastics?
3. Is the cornstarch needed for the production of bioplastics genetically manipulated?
In contrast to other fields of application such as bio petrol the needed quantities of renewable raw materials for the bioplastics still are very little.
Nowadays, most of the raw material manufacturers only use the secondary products of the plants which are not suitable for the production of food and fodder. If this is not possible, the needed raw materials are another source of income for farmers. Due to the surplus of food in the industrial countries these exclusive productions are not to be seen as a destructive effect because otherwise the fields would be left unexploited.
On average about one hectare of herbal yield is needed for two tons of bioplastics.
Most of the maize needed for the current plastic production is genetically manipulated due to its resistance to fungi and bacteria. During the complex production process the cornstarch gets converted so that the granules won’t have a manipulated DNA later on.
