Biodégradable – Guide pratique des allégations environnementales à l’usage des professionnels et des consommateurs

Un produit ou un emballage peut se revendiquer biodégradable s’il respecte des normes en vigueur (notamment la norme NF EN 13 432 : 2000). Ces normes définissent les conditions dans lesquelles le produit peut effectivement se dégrader. Elles garantissent que le produit va se décomposer sous l’action d’organismes vivants en éléments divers dépourvus d’effet dommageable [...]
Biotechnology: Researcher Jean-Paul Meijnen (TU Delft) has ‘trained’ bacteria to convert all the main sugars in vegetable, fruit and garden waste efficiently into high-quality environmentally friendly products such as bioplastics. There is considerable interest in bioplastics nowadays. The technical problems associated with turning potato peel into sunglasses, or cane sugar into car bumpers, have already [...]
Bioplastics are derived from renewable sources and may contain substantial amounts of biobased materials and/or exhibit biodegradation under various conditions. In essence, bioplastics describe two concepts at the same time: disposability and renewable sourcing. Both are driven by environmental sustainability, which includes the desire to reduce greenhouse-gas emissions (notably of carbon dioxide, CO2), to [...]
Global bioplastic packaging demand is forecast to reach 884,000 tonnes by 2020. A 24.9% CAGR is expected from 2010-15 slowing to 18.3% in the five years to 2020. According to a major new study by Pira International, a new breed of bioplastics will be major drivers as packaging market demand gradually shifts from biodegradable [...]
Your favorite catsup or fruit juice might be “hot-filled” at the food-processing plant—that is, poured into its waiting container while the catsup or juice is still hot from pasteurization. Current containers made from corn-based plastics literally can’t take the heat of hot-filling, according to U.S. Department of Agriculture (USDA) chemist William J. Orts. But [...]
Solvay is studying the construction of an epichlorohydrin production plant in Taixing, China, with an initial capacity of 100,000 tons per year. The plant, which is expected tostart producing in 2013, will be based on innovative Epicerol® technology. The plant is set to serve the rapidly growing Chinese epichlorohydrin market, which currently represents 29% of the [...]
Un grupo de investigadores del Instituto de Ciencias Materiales de Sevilla del Consejo Superior de Investigaciones Científicas (CSIC) y la Universidad de Sevilla (US) y de la Universidad de Málaga (UMA) han patentado un plástico biodegradable procedente de la piel de tomate con aplicaciones en el campo de la alimentación y salud, entre otros. [...]
Dr. Richard Gross, professor of chemical and biological science at Polytechnic Institute of New York University (NYU-Poly), has developed a method for producing a strong, highly ductile bioplastic using yeast and one of nature’s simplest building blocks: fatty acids of plant oils. Like all plastics, the new material is a polymer — a large [...]
In this article we will look very simply at Vacuum Forming and the basic principles behind it. In spite of the different applications there are available, and the “easy to use” equipment in the market place, it is, in my opinion, and certainly in terms of volume and consistency, still best produced by the “experts.”
Briefly, [...]
Plastic injection molding involves giving shape to molten plastic into different shapes that are required for our day-to-day life. That kind of mechanism for plastic is quite expensive and very complicated. Even the machines involved costs a great deal. Known as injection molding, the machines are solid, and some even weigh a kilo tones.
However, it [...]
In 1855, Alexander Parkes invented the first synthetic plastic. The invention of plastic has changed the world of manufacturing forever. And as plastics are continuing to be developed with different properties, the usefulness of such a product continues to grow. Plastics are now used in a variety of industries, including medicine, food service, and pretty [...]
