Abstract:

Plastics pose a huge threat to the environment. Plastic accumulation in the land and the seas is now the world’s most terrorising problem, mainly because of its non-degrading character. Plastic degradation has always been a next to impossible concept in the field of science, but nanotechnology provides a revolutionary and modern way to solve the problem of plastic accumulation in the environment. One of the great advantages of nanoparticles is that we can increase and decrease the rate of biodegradation depending on our needs. Nanoparticles enhance the polythene degradation capacity of the mic

Plastics are light weighted, durable, corrosion resistant materials, strong, and inexpensive. Scientists have reported many adverse effects of the plastic in the environment and human health. Nowadays biodegradable plastics are considered as the environmental friendly. The plastic polymers as such at room temperatures are not considered as toxic. The toxic properties are found in plastics, when heat is released from the food material in which they are covered and then they produce serious human health problems.

Abstract:

In the mid-twentieth century, the solid waste generated was mostly made of biodegradable materials. However, the invention of plastic and its widespread use have led to a staggering accumulation of plastic in the environment, posing a severe threat to the biosphere. The environmental degradation of plastic can take thousands of years and poses a significant concern for environmental and human health. Until recently, it was thought that some plastics were non-biodegradable; however, there are microorganisms capable of degrading both plastics derived from fossil resources and those from biomass

The resistance of plastic textiles to environmental degradation is of major concern as large portions of these materials reach the ocean. There, they persist for undefined amounts of time, possibly causing harm and toxicity to marine ecosystems. As a solution to this problem, many compostable and so-called biodegradable materials have been developed. However, to undergo rapid biodegradation, most compostable plastics require specific conditions that are achieved only in industrial settings. Thus, industrially compostable plastics might persist as pollutants under natural conditions. In this wo

However, materials for outdoor use suffer from the negative effects of environmental factors, loosing properties in various degrees. In particular, natural fillers (particulates or fibers) or components induce biodegradability in the otherwise bio inert matrix of usual commodity plastics. Here we present some aspects found in recent literature related to the effect of aggressive factors such as temperature, mech

Abstract:

Implementation of material value conservation (MVC) needs to be proven through research to determine impact upon plastic properties such as optical properties of virgin plastic and recycled plastic blends. Optical properties such as colour, transparency and gloss are important parameters for appropriate quality of plastic packaging. Degradation of optical properties occurs during recycling processes of plastic materials and the declining properties of recycled products could be improved by blending them with virgin materials. This research aims to reveal the impact of repetitive recycling on o

Abstract:

Mechanical recycling of plastic film involves subjecting plastic materials to a series of heat cycles that can potentially degrade the material, causing brittleness and increased melt viscosity. Plastic film recycling in the UK is in its infancy, in need of an increased understanding of how the physical properties of polymeric materials change before and during the process. Reliable data are required to estimate the behaviour of such film products when recycled. Measurements were made as to the changes in physical properties of four different varieties of polyethylene (PE) film products when s

Plastic is composed of synthetic and semi-synthetic compounds with immense applications. While Plastics are dangerous and harm the environment, their practice is causing their ingesting to grow. Outdated methods of plastic degradation through physical and chemical means like landfill, incineration, and recycling are expensive and perilous and release hazardous chemical substances to the environment. Thus, proper approaches are required to overcome this trick. Biodegradation through microbes on the other hand offers a hopeful solution. Presently, numerous categories of bacteria and other microb

In order to accurately determine the degradation performance of polyolefin-based degradable plastics, the concept of bioassimilated carbon is proposed for the first time in this paper; the bioactive and hydrophilic organic carbon in plastic degradation products is defined as bioassimilation carbon. A method for the detection of the carbonyl index and bioassimilated carbon conversion rate in polyolefin degradable plastics was developed to quickly identify its degradation performance. The measurement results show that the bioassimilated carbon conversion rate of more than 70% can be used to repl

The current research explored the potential of microalgal species Chlorella vulgaris and Pretreatment to remediate plastic waste. It was concluded from the results that Pretreatment had a marked effect on the cracking and alteration of plastic polymer, which helped to grow microbial species on the cracked surface as evident by Compound Microscopy (CM), Scanning Electron Microscopy (SEM), and Fourier Transformed Infrared Spectroscopy (FTIR) analysis. FTIR data also supported the notion that in the absence of any pretreatment, the microbial species were not able to mediate plastic biodegradation
