Another way that plastic consumption and pollution results in increasing climate change rates, is from incineration of plastic waste. This releases way more toxins into the air and then it all gets consumed by ocean water. The oceans end up taking up chemicals, but also the small pieces of plastic that were not fully broken down.
Higher amounts of plastic ended up in the ocean, especially plastic from medical waste and masks. [26] [27] Several news reports point to a plastic industry trying to take advantage of the health concerns and desire for disposable masks and packaging to increase production of single use plastic. [28] [29] [30] [31]
The PCD aims to have them removed from all bottled water containers by the end of 2018. According to the PCD, Thailand produces 4.4 billion plastic drinking water bottles per year. Sixty percent, or 2.6 billion, of these bottles have cap seals. The weight of the plastic cap seals alone is around 520 tonnes per year. [18]
Haiti has no collective system for waste collection and treatment, [277] and thus plastic is often disposed of in urban water evacuation canals, which then degrade to form microplastics. Due to tropical temperatures and average daily duration of 12 hours, [ clarify ] the plastics present in urban waterways could degrade more rapidly.
Widespread use of plastic drinking water sachets due to lack of available potable water has also led to increased plastic pollution, often polluting water bodies, choking storm-water drains and causing death of livestock. [26] The country's gold mining industry has polluted 60% of Ghana's waters. [27] [28]
Plastic resin pellets are classified as primary microplastics, meaning that they were intentionally produced at sizes ranging from 1–5 mm in diameter (whereas secondary microplastics are created through photodegradation and weathering of larger pieces of plastic, like water bottles and fishing nets).

Since the systems are staged, the culture of the later stages can be acclimated to the slowly degraded materials. [8]: Ch 2 The discs consist of plastic sheets ranging from 2 to 4 m in diameter and are up to 10 mm thick. Several modules may be arranged in parallel and/or in series to meet the flow and treatment requirements.
