Everyday human life cannot be separated from plastic. Almost all objects that are around us are made of plastic. In general, plastics are non-biodegradable, causing environmental problems caused by the increased volume of plastic waste. One way to overcome this is by recycling existing plastic waste. But the use of recycled plastics is very limited and considered inefficient because the process is more difficult and processing is more expensive than buying new plastic raw materials. Another alternative is to use bioplastics or biodegradable plastic. This plastic is more environmentally friendly because it is biodegradable or easily decomposed by microorganisms. Basically, bioplastics can be made from vegetable starches. In this study we will use starch extracted from banana peel waste as a base material for making bioplastics. In this research, glycerin which is used as a bioplastic adhesive or plasticizer will be used. Whether or not bioplastics depend on the resistance to water, the attractiveness of the bioplastics, the ability of the plastic to be decomposed by microorganisms. From this research, it is expected to produce bioplastics with high water resistance and high tensile strength and easy to decompose microorganisms.

Plastic is used in many forms in day-to-day life. Since Plastic is non-biodegradable, landfills do not provide an environment friendly solution. Hence, there is strong need to utilize waste plastic. This creates a large quantity of garbage every day which is unhealthy and pollutes the environment. In present scenario solid waste management is a challenge in our country. The production of solid waste is increasing day to day and causes serious concerns to the environment. In this study, the recycled plastics are used in the concrete as a partial replacement of fine aggregate in concrete. The main purpose of this study is to investigate the mechanical properties of concrete such as workability, compressive, flexural and split tensile strengths of concrete mixes with partial replacement of conventional fine aggregate with aggregate produced from plastic waste. The use of plastic aggregate as replacement for fine aggregate enhances workability and fresh bulk density of concrete mixes. The mechanical properties of concrete such as compressive, flexural, and tensile strengths of concrete reduced marginally up to 10% replacement levels.

For more than half a century, plastic prod-ucts have been a part of people’s lives. When plastic waste is thrown into nature, it can cause a sequence of dangerous effects. Previous researchers esti-mated that global plastic waste in 2020 will be more than 400 million tons. To reduce plastic waste, they built scientific models to analyze the sources of plas-tic and provided solutions for regenerating these plastic wastes. However, their models are static and inaccurate, which may cause some false predictions.In this paper, we first observe the distribution of the real-world plastic waste data. Then, we build simple exponential growth model and logistics model to match these data. By testing different models on our plots, we discover that the SELF-ADAPTIVE MODEL is the best to describe and correctly predict our future plastic waste production, as this model combines the benefits of SIMPLE EXPONENTIAL GROWTH MODEL and the LOGISTIC MODEL. The self-Adaptive model has the potential to minimize the error rate and make the predictions more accurate. Based on this model, we can develop more accurate and informative solu-tions for the real-world plastic problems.

Virgin polymers based on petrochemical feedstock are mainly preferred by most plastic goods manufacturers instead of recycled plastic feedstock. Major reason for this is the lack of reliable information about the quality, suitability, and availability of recycled plastics, which is partly due to lack of proper segregation techniques. In this paper, we present our ongoing efforts to segregate plastics based on its types and improve the reliability of information about recycled plastics using the first-of-its-kind blockchain smart contracts powered by multi-sensor data-fusion algorithms using artificial intelligence. We have demonstrated how different data-fusion modes can be employed to retrieve various physico-chemical parameters of plastic waste for accurate segregation. We have discussed how these smart tools help in efficiently segregating commingled plastics and can be reliably used in the circular economy of plastic. Using these tools, segregators, recyclers, and manufacturers can reliably share data, plan the supply chain, execute purchase orders, and hence, finally increase the use of recycled plastic feedstock.

Increase in the energy usage and declining of non-renewable fossil fuels has changed the perceptions to energy recovery methods to satisfy the need of the energy. Through extensive research and innovation of technology, especially to recover the plastic waste to energy feedstock has been developed. The chosen plastic waste samples are polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP). This sample is collected from daily household waste and was characterized according to the resin types or plastic types. In this research the determination of the moisture content and ash analysis has been carried out using proximate analysis and also determination of the carbon, hydrogen, nitrogen, and sulphur content has been carried out by using the ultimate analysis. In addition, the calorific value of the samples has been determined and activation energy is obtained based on thermogravimetric analysis (TGA) data. The chosen kinetic modelling is modified Arrhenius equation. According to the results, HDPE was the best choice for energy recovery from waste plastics in Malaysia due to high calorific value, low activation energy, low moisture content and ash content and it has low sulphur content among all the plastic samples experimented.

Abstract The EU Directive 5 June 2019, n. 904, aims to promote sustainable reusable products and systems in a circular perspective, reducing the production of disposable products and waste. Abandoned plastics take decades to disintegrate, never disappearing completely from the environment, with serious consequences for human health. A study conducted by the European Food Safety Authority (EFSA) has found that pollutants such as polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) or bisphenol A (BPA) can accumulate in microplastics, which are swallowed by humans as well as inhaled or ingested reaching lungs. For instance, it has been estimated that every week we ingest the same amount of microplastics as a credit card. Furthermore, plastic kills and damages biodiversity. Aquatic animals are the most affected, as they are either trapped in man-made plastic waste or they swallow plastics with serious damage to their and the humans' health that eat them. Dangerous are also nanoplastics that can penetrate cell walls and are chemically more reactive. However, Directive 2019/904/EU does not eliminate the use of plastic, setting the percentages of recycled plastics to be used in the manufacture of disposable plastic products. For instance, beverage PET bottles must contain at least 25% of recycled plastic from 2025 and 30% from 2030. Despite the Directive has provided elements for states to legislate in favour of a society that makes less use of plastics, today no zero- plastic society has been created. In order to achieve this 'zero' it is necessary to start from the citizens, raising their awareness through awareness-raising campaigns and the distribution of leaflets and posters on the consequences of the mismanagement of plastic waste (and microplastics) on their health and on the environment. Key messages Raise citizens awareness on the consequences of the mismanagement of plastic waste (and microplastics) on their health and on the environment is fundamental. The importance of the creation of a zero plastic society thanks to the application of Directive 2019/904/EU at international level.

Recycled Waste

The utilization of a large amount of waste in concrete production is considered the best alternative for solving the issues associated with improper disposal. Plastic waste is considered as one of such waste and could be utilized in several applications. The drawback associated with the utilization of a large amount of plastic waste is the decrease in the mechanical properties of the mortar or concrete as the case may be. This paper presents a detailed review about waste recycled plastics and research published on the effect of non-irradiated recycled plastic on the mechanical properties of cement mortar and cement concretes as either fillers or aggregates and the application of gamma radiation on the recycled plastic waste. The effect of recycled waste plastic on compressive strength, flexural strength and splitting tensile strength is discussed in this paper.

Wastes from landfills originate from many spheres of life. These are produces as a result of human activities either domestically or industrially. The global plastic production increased over years due to the vast applications of plastics in many sectors. The continuous demand of plastics caused the plastic wastes accumulation in the landfill consumed a lot of spaces that contributed to the environmental. In addition, economic growth and development also increased our demand and dependency on plastics which leads to its accumulation in landfills imposing risk on human health, animals and cause environmental pollution problems such as ground water contamination, sanitary related issues, etc. The management and disposal of plastic waste have become a major concern, especially in developing cities. The idea of waste to energy recovery is one of the promising techniques used for managing the waste of plastic. Hence, this paper aims review at utilizing of plastic as an alternative fuel.
