Les plastiques actuels, à base de pétrole, nous ont menés dans un cul-de-sac. Toxiques et persistants dans l'environnement, ils sont néfastes autant pour la santé humaine que pour la faune en général. Et le recyclage, qui devait leur procurer une jeunesse éternelle, ne fonctionne tout simplement pas: bon an mal an, moins de 10% du plastique produit est recyclé et revalorisé, le reste terminant sa course dans les dépotoirs et la nature… Le plastique n'en reste pas moins un matériau aux qualités indéniables dont les sociétés industrielles modernes peuvent difficilement se passer. Comment le transformer en un produit sain et à durée contrôlable? Par chance, un substitut avantageux existe: le bioplastique. Dans cet ouvrage de vulgarisation scientifique, le docteur en biophysique Paul Lavallée présente un panorama complet des avantages de ce matériau fabriqué à partir d'éléments organiques (végétaux, résidus alimentaires, algues…). Dans les conditions appropriées, le bioplastique a la propriété de se décomposer en compost ou en biométhane sous l'action de bactéries, sans tri préalable, ce qui vient pallier les insuffisances du recyclage actuel. Plan de conversion à l'appui, ce livre essentiel montre comment le bioplastique, même s'il a généralement mauvaise presse, ouvre véritablement un avenir beaucoup plus sain pour l'environnement et le vivant. Mais pour que la pollution plastique cesse de poser un risque pour les générations futures, l'humanité aura un choix à faire: soit les pétroplastiques, soit les bioplastiques, mais pas les deux! Paul Lavallée nous donne les clés pour faire ce choix de façon éclairée.

Plastics are everywhere. Bags, bank cards, bottles, and even boats can all be made of this celebrated but much-maligned material. Yet most of us know next to nothing about plastics. We do know that they are practical and cheap--but they also represent a huge environmental problem, for they literally take ages to decompose. In this engaging book, E.S. Stevens tells us everything we have always wondered about plastics and of the efforts, in America, Europe, and Asia, to develop a new breed of environmentally friendly plastics. He points to a possible future where plastics will no longer be made of petroleum, but of plants. The first two chapters assess the increased use of plastics as a relatively new alternative to other materials. The third chapter introduces us to their impact on the environment and strategies for their disposal or recycling. The next two chapters cover basic concepts and terms used in polymer sciences and provide some basic chemistry. With these fundamentals in tow, the author compares how petroleum-based and biological polymers are made, and the various ways in which they decompose. He acquaints readers with the emerging technologies, their commercial viability, and their future. Finally, instructions are given for preparing basic bioplastics using readily available materials. Nonspecialists will find Green Plastics a concise introduction to this exciting interdisciplinary topic--an introduction otherwise not available. For students it provides easy entry to an area of science with wide appeal and current importance; for teachers, excellent background reading for courses in various sciences. The prospect of depleted fossil fuel supplies, and the potential benefits of bioplastics to the environment and to rural areas that could supply the raw materials, make this book a compelling presentation of a subject whose time has come.
