  2. Life-cycle assessment - Wikipedia

    en.wikipedia.org/wiki/Life-cycle_assessment

    Life cycle energy analysis (LCEA) is an approach in which all energy inputs to a product are accounted for, not only direct energy inputs during manufacture, but also all energy inputs needed to produce components, materials and services needed for the manufacturing process. [110] With LCEA, the total life cycle energy input is established. [111]

    en.wikipedia.org/wiki/Product_lifecycle

    A generic lifecycle of products. In industry, product lifecycle management (PLM) is the process of managing the entire lifecycle of a product from its inception through the engineering, design, and manufacture, as well as the service and disposal of manufactured products.

  5. Plastic recycling - Wikipedia

    en.wikipedia.org/wiki/Plastic_recycling

    Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.

    Engineering plastic; Filaments; Non-woven; Packaging stripes; Staple fibre. Choosing the re-pelletizing way means having an additional conversion process that is, at the one side, energy-intensive and cost-consuming, and causes thermal destruction. At the other side, the pelletizing step is providing the following advantages: Intensive melt ...

    The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.

  8. Technology life cycle - Wikipedia

    en.wikipedia.org/wiki/Technology_life_cycle

    The technology life cycle (TLC) describes the commercial gain of a product through the expense of research and development phase, and the financial return during its "vital life". Some technologies, such as steel, paper or cement manufacturing, have a long lifespan (with minor variations in technology incorporated with time) while in other ...

  9. Biodegradable plastic - Wikipedia

    en.wikipedia.org/wiki/Biodegradable_plastic

    A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
