Biodegradable materials definition

Biodegradable materials means those made of cellulose-based or other substances that are capable of being readily attacked, decomposed, assimilated, and otherwise completely oxidized or broken down by bacteria or other natural biological organisms into carbonaceous soil material or water and carbon dioxide within a reasonable period of time.

Biodegradable materials means renewable lignocellulosic materials (i.e., plant dry matter - here described as natural material). Those materials shall degrade in normal conditions of the use of DFADs and both be biodegradable in marine environments in accordance with international relevant standards for full biodegradability in marine environments and on land under natural environmental conditions. In addition, the substances resulting from the degradation of these materials shall not be toxic for the marine and coastal ecosystems or include heavy metals in their composition.

Related to Biodegradable materials

  • Biodegradable means degradable through a process by which fungi or bacteria secrete enzymes to convert a complex molecular structure to simple gasses and organic compounds.

  • Fissile material means the radionuclides uranium-233, uranium-235, plutonium-239, and plutonium-241, or any combination of these radionuclides. "Fissile material" means the fissile nuclides themselves, not material containing fissile nuclides. Unirradiated natural uranium and depleted uranium and natural uranium or depleted uranium, that has been irradiated in thermal reactors only, are not included in this definition. Certain exclusions from fissile material controls are provided in 10 CFR 71.15.

  • Recyclable Materials means materials that are separated from mixed municipal solid waste for the purpose of recycling or composting, including paper, glass, plastics, metals, automobile oil, batteries, source-separated compostable materials, and sole source food waste streams that are managed through biodegradative processes. Refuse-derived fuel or other material that is destroyed by incineration is not a recyclable material. (Minn. Stat. § 115A.03, Subd. 25a)

  • Biological Samples means any physical samples obtained from Study Participants in accordance with the Protocol for the purposes of the Study.

  • Biological Materials means any material (including, without limitation, plants, animals, microbes or viruses) of biological origin which contains genetic information capable of reproduction and/or material derived from the same that is collected or produced through the Contract;
