Basics Glossary Humus In

Basics Glossary Humus In agriculture, “humus“ is often used simply to mean mature à compost, or natural compost extracted from a forest or other spontaneous source for use to amend soil. Hydrophilic Property: “water-friendly“, soluble in water or other polar solvents (e.g. used in conjunction with a plastic which is not waterresistant and weatherproof or that absorbs water such as Polyamide (PA)). Hydrophobic Property: “water-resistant“, not soluble in water (e.g. a plastic which is waterresistant and weatherproof, or that does not absorb any water such as Polethylene (PE) or Polypropylene (PP)). Microorganism Living organisms of microscopic size, such as bacteria, funghi or yeast. PCL Polycaprolactone, a synthetic (fossil based), biodegradable bioplastic, e.g. used as a blend component. PHA Polyhydroxyalkanoates are linear polyesters produced in nature by bacterial fermentation of sugar or lipids. The most common type of PHA is à PHB. PHB Polyhydroxyl buteric acid (better poly-3-hydroxybutyrate), is a polyhydroxyalkanoate (PHA), a polymer belonging to the polyesters class. PHB is produced by micro-organisms apparently in response to conditions of physiological stress. The polymer is primarily a product of carbon assimilation (from glucose or starch) and is employed by micro-organisms as a form of energy storage molecule to be metabolized when other common energy sources are not available. PHB has properties similar to those of PP, however it is stiffer and more brittle. PLA Polylactide, a bioplastic made of polymerised lactic acid. Saccharins or carbohydrates Saccharins or carbohydrates are name for the sugar-family. Saccharins are monomer or polymer sugar units. For example, there are known mono-, di- and polysaccharose. à glucose is a monosaccarin. They are important for the diet and produced biology in plants. Sorbitol Sugar alcohol, obtained by reduction of glucose changing the aldehyde group to an additional hydroxyl group. S. is used as a plasticiser for bioplastics based on starch . Starch Natural polymer (carbohydrate) consisting of à amylose and à amylopectin, gained from maize, potatoes, wheat, tapioca etc. When glucose is connected to polymer-chains in definite way the result (product) is called starch. Each molecule is based on 300 -12000-glucose units. Depending on the connection, there are two types à amylose and à amylopectin known. Starch (-derivate) Starch (-derivates) are based on the chemical structure of à starch. The chemical structure can be changed by introducing new functional groups without changing the à starch polymer. The product has different chemical qualities. Mostly the hydrophilic character is not the same. Starch-ester One characteristic of every starch-chain is a free hydroxyl group. When every hydroxyl group is connect with ethan acid one product is starch-ester with different chemical properties. Starch propionate and starch butyrate Starch propionate and starch butyrate can be synthesis by treating the à starch with propane or butanic acid. The product structure is still based on à starch. Every based à glucose fragment is connected with a propionate or butyrate ester group. The product is more hydrophobic than à starch. Sustainable An attempt to provide the best outcomes for the human and natural environments both now and into the indefinite future. One of the most often cited definitions of sustainability is the one created by the Brundtland Commission, led by the former Norwegian Prime Minister Gro Harlem Brundtland. The Brundtland Commission defined sustainable development as development that „meets the needs of the present without compromising the ability of future generations to meet their own needs.“ Sustainability relates to the continuity of economic, social, institutional and environmental aspects of human society, as well as the non-human environment). Thermoplastics Plastics which soften or melt when heated and solidify when cooled (solid at room temperature). Yard Waste Grass clippings, leaves, trimmings, garden residue. 38 bioplastics MAGAZINE [07/04] Vol. 2
