  2. 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 ...

  3. 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 ...

    According to chemists that specialize in plastic alternatives, most conventional plastics could theoretically be replaced by PHA, but its biodegradable qualities are better suited for single-use ...

  5. Marine plastic pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_plastic_pollution

    The largest ocean-based source of plastic pollution is discarded fishing gear (including traps and nets), estimated to be up to 90% of plastic debris in some areas. [56] [57] Continental plastic litter enters the ocean largely through storm-water runoff, flowing into watercourses or directly discharged into coastal waters. [58]

    en.wikipedia.org/wiki/Plastisphere

    A more recent concern in microplastic pollution is the use of plastic films in agriculture. 7.4 million tons of plastic film are used each year to increase food production. [22] Scientists have found that microbial biofilms can form within 7–14 days on plastic film surfaces, and have the ability to alter the chemical properties of the soil ...

  7. Biodegradable polymer - Wikipedia

    en.wikipedia.org/wiki/Biodegradable_polymer

    First, the properties such as weight capacity of biodegradable polymer are different from the traditional polymer, which may be unfavorable in many daily applications. Second, engineering issues. Biodegradable polymers are mostly plant-base materials, which means they originally come from organic source like soybean or corn.

  9. Marine pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_pollution

    Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
