    Modern society has has a big problem when it comes to plastic -- and it's contributing heavily to pollution and climate change. Globally, 400 million metric tons of plastic are produced each year ...

  3. Bioplastic - Wikipedia

    en.wikipedia.org/wiki/Bioplastic

    [59] [60] The environmental impact of bioplastics is often debated, as there are many different metrics for "greenness" (e.g., water use, energy use, deforestation, biodegradation, etc.). [61] [62] [63] Hence bioplastic environmental impacts are categorized into nonrenewable energy use, climate change, eutrophication and acidification. [64]

  4. Biodegradable plastic - Wikipedia

    en.wikipedia.org/wiki/Biodegradable_plastic

    Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...

    en.wikipedia.org/wiki/Plastic_pollution

    The United Nations Environment Programme used 2 different studies to estimate the impact of plastic on climate: according to the first, by the year 2040 the annual emissions from plastic will reach 2.1 GtCO2 and will consume 19% of the 1.5 degrees carbon budget, while the second estimated the emissions in the year 2015 as 1.7 GtCO2 and ...

    Furthermore, plastic bottles and plastic bags that end up in landfills are frequently consumed by animals, which then clogs their digestive systems and leads to death. [4] Because of the substantial growth in plastic consumption, biodegradable additives are becomingly increasingly necessary to increase the rate of degradability of common plastics.

  7. Plastic degradation by marine bacteria - Wikipedia

    en.wikipedia.org/wiki/Plastic_degradation_by...

    Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...

  8. Biodegradable bag - Wikipedia

    en.wikipedia.org/wiki/Biodegradable_bag

    In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.

  9. Global plastic pollution treaty - Wikipedia

    en.wikipedia.org/wiki/Global_plastic_pollution...

    Members agreed that the treaty will be international in scope, legally binding, and should address the full life cycle of plastics, including its design, production, and disposal. [4] It has been argued that chemicals contained in plastics such as additives, processing aids, and unintentionally added substances need to be addressed, too. [16] [17]
