Abstract
Plastics have outgrown most man-made materials and have long been under environmental scrutiny. However, robust global information, particularly about their end-of-life fate, is lacking. By identifying and synthesizing dispersed data on production, use, and end-of-life management of polymer resins, synthetic fibers, and additives, we present the first global analysis of all mass-produced plastics ever manufactured. We estimate that 8300 million metric tons (Mt) as of virgin plastics have been produced to date. As of 2015, approximately 6300 Mt of plastic waste had been generated, around 9% of which had been recycled, 12% was incinerated, and 79% was accumulated in landfills or the natural environment. If current production and waste management trends continue, roughly 12,000 Mt of plastic waste will be in landfills or in the natural environment by 2050.

Out of sight, out of mind: Plastic waste exports, psychological distance and consumer plastic purchasing

TL;DR: In this article, the authors propose that plastic waste is a problem that is perceived as "out of sight and out of mind" for consumers in high plastic consumption (typically high income) countries and that this is influenced by the export of plastic waste to other (typically lower income and lower consumption) countries for disposal.

Distinct microbial metabolic activities of biofilms colonizing microplastics in three freshwater ecosystems

TL;DR: Overall findings demonstrated that as specific niches, MPs influenced microbial-mediated carbon cycling in the freshwater ecosystems and MPs-promoted microbial communities posed ecological significance.

Tat-Independent Secretion of Polyethylene Terephthalate Hydrolase PETase in Bacillus subtilis 168 Mediated by Its Native Signal Peptide.

TL;DR: PETase, which exhibits much higher PET-hydrolytic activity than other enzymes, was successfully secreted into extracellular milieu from Bacillus subtilis 168 under the direction of its native signal peptide (named SPPETase).

Marine microplastic: Preparation of relevant test materials for laboratory assessment of ecosystem impacts

TL;DR: Comparison of different analytical approaches showed that creation of a homogeneous microplastic mixture is possible, representing a first step in closing the gap between laboratory studies with pristine materials and realistic scenarios with weathered microplastics.

Plastic waste inputs from land into the ocean

TL;DR: This work combines available data on solid waste with a model that uses population density and economic status to estimate the amount of land-based plastic waste entering the ocean, which is estimated to be 275 million metric tons.

Accumulation and fragmentation of plastic debris in global environments.

TL;DR: Global plastics production and the accumulation of plastic waste are documented, showing that trends in mega- and macro-plastic accumulation rates are no longer uniformly increasing and that the average size of plastic particles in the environment seems to be decreasing.

What a Waste : A Global Review of Solid Waste Management

TL;DR: In this paper, the authors estimate that the amount of municipal solid waste (MSW) generated by urban populations is growing even faster than the rate of urbanization and that by 2025 this will likely increase to 4.3 billion urban residents.

What are the current trends in the production and consumption of plastics?

Current trends show 8300 million metric tons of virgin plastics produced, with 6300 million metric tons of plastic waste generated by 2015. Only 9% recycled, 12% incinerated, and 79% landfilled or in the environment.
