The research status and mechanisms of insect and intestinal microorganism-based plastic degradation are reviewed herein. Based on the current research status and considering the influence of multiple factors in the degradation process, two main approaches for investi...
We’ve discovered microorganisms that naturally feed off the chemicals and compounds inplasticwaste by digesting and breaking them down into harmless organic matter. And now we're enhancing these microorganisms and enzymes associated with the degradation. Distributing these enhanced microorganisms and enzyme...
Decomposition mechanisms of plastic include 1) photo-oxidation, physical weathering, plowing and harrowing as well as 2) degradation by microorganisms (Sander, 2019). The (bio)degradation-induced generation of secondary MPs and NPs in agricultural soils is a major issue of concern as at the micro...
Pyrolysis mainly refers to the transformation of a big chain polymer to a smaller one by thermal degradation. In this process, the temperature range varies from 300 to 900 °C under an inert gas atmosphere (Chen et al.2014). Various important products like liquid oil, gas, etc. (WtE) are...
Nevertheless, the interactions between plastic and microorganisms are still poorly known. Here, we present a review of current knowledge on plastic degradation and plastic-microorganism interactions in cold marine habitats. Moreover, we highlight the advantages of microorganisms isolated from this ...
As an ecofriendly alternative for existing industrial recycling processes for plastic waste as well as for bioremediation of environments polluted with plastic particles, an efficient biological degradation of plastics via microorganisms/enzymes is highly desirable. However, there are only very few microbial...
Plastic debris widely pollutes freshwaters. Abiotic and biotic degradation of plastics releases carbon-based substrates that are available for heterotrophic growth, but little is known about how these novel organic compounds influence microbial metabolis
Biodegradable polymers can break down into smaller molecules, such as CO2, CH4and H2O, by microorganisms under aerobic or anaerobic conditions. Although not always required, abiotic chemical reactions like photodegradation, oxidation and hydrolysis can also aid the degradation process9. There are many ...
Commonly used methods for plastic disposal were proved to be inadequate for effective plastic waste management, and hence there is growing concern for use of efficient microorganisms meant for biodegradation of non-degradable synthetic polymer. The biodegradable polymers are designed to degrade fast by ...
The biodegradability of organic substances is the degree of the changes in physical and chemical characteristics and molecular structure of organic substances under degradation by microorganisms. Fig. 1 illustrates the biodegradation processes of organic substances under aerobic conditions (Jiang et al., 20...
