| Bioplastics: Frequently Asked Questions (FAQs) |
| 2008-07-01 14:30:07 |
WHAT ARE BIOPLASTICS ?
Two different concepts underlie the term ‘Bioplastics’:
a) Compostable plastics certified according to EN13432 and based on renewable (biobased) and/or non-renewable (fossil) resources
The focus here is on their functionality “compostability”. Industrial users, consumers and waste management operators need to be able to identify products and assign them to composting where appropriate. The compostability [...]

| Les biomatériaux et les fibres naturelles dans l’automobile - Un point de vue ! |
| 2008-06-30 01:27:04 |
La montée du prix du pétrole donne une impulsion au développement des biomatériaux et des fibres naturelles dans l’automobile. Ce facteur ajouté aux inquiétudes de nature écologique concernant les émissions de gaz à effet de serre et une forte concurrence mondiale font que des applications industrielles à partir des biomatériaux voient le jour, tout particulièrement [...]
