Abstract:

In this paper, material flows and resource potentials for plastics at a national level in Denmark are mapped using an Environmentally Extended Multiregional Input-Output (EE-MRIO) database. EE-MRIO offers an operative improvement to current and prevalent methods for assessing the industrial and societal metabolism of resources, including plastics. The Exiobase is applied to map (1) the major sources, (2) calculate the total supply, (3) uses of plastics and waste generation, and (4) end of life pathways in order to indicate the potentials of plastics in the circular economy in Denmark with a fo

Abstract:

The usage of plastics has exponentially increased in our daily lives over the past 50 years because of its durability, low costs and potential for diverse applications, such as widespread use as disposable items. In this study, first, the recycling cost of plastic wastes has been estimated by using actual data taken from a recycling centre, where plastic solid wastes were collected separately. The total amount of plastic wastes recycled at the centre was approximately 695 tonnes. The operating cost of plastics separation at the recycling centre, the transport of plastic wastes, labouring, main

Abstract:

More than 420,000 tonnes of plastic waste is produced every year in New York City (NYC). This plastic represents 15% of municipal solid waste in NYC and is in line with New York State and United States averages. This material is managed by NYC’s dual-stream recycling system and industry-leading material recovery facilities. However, not all plastic collected for recycling (diverted) is ultimately sold to be remanufactured into new products (recovered). This study utilizes publicly available data to quantify and compare the diversion and recovery rates of residential plastics in NYC to provide

Abstract:

Plastic has brought great convenience to people’s lives, but it has also brought severe environmental pollution to the world. It is almost impossible to break down entirely in nature, and plastic waste, whether in rivers, oceans, or on land, can persist in the environment for centuries. The problem of plastic waste disposal has caused worldwide concern. It is necessary to reduce the production of plastic products through global cooperation effectively. However, achieving this goal will also involve some unexpected issues, such as controlling the adverse economic impact of plastics, and the rat

Marine plastic waste has been an important global environmental issue in recent years, and quantifying the amount of global marine plastic waste input is vital for control and mitigation. However, determining an accurate quantity of oceanic plastics is challenging because comprehensive monitoring data are difficult to obtain on national and global scales. To understand the contribution of China in global marine plastic waste input, we used a material flow analysis (MFA) method, which is included in lifecycle assessment and combines statistical data from China’s official statistics, reports, an

Abstract:

Due to rise in unleashed industrial development, our world is now engulfed by solid wastes. In that huge pile of wastes, plastic is one of the prime culprits for degrading our nature. The used plastics (which are not recycled) are either end up in oceans or landfills and continue to create environmental problems. On regular basis, thousands of tonnes of plastic waste is being created all around the world. In some cases, recycling plastic is costlier than using virgin plastic. Hence there is a necessity to create a situation in which adequate price for recycling plastic must come into play. Suc

Agricultural activities have been positively affected by the use of plastic products, but this has resulted in the production of plastic waste and led to an increase in environmental pollution. To continue benefiting from the use of plastics but addressing at the same time the environmental issue, two strategies seem viable: the development of technologies for extending plastics lifespan and the gradual replacement of traditional non-biodegradable materials by biodegradable ones, at least for some products.

Abstract:

Multilevel statistical entropy analysis (SEA) is a method that has been recently proposed to evaluate circular economy strategies on the material, component and product levels to identify critical stages of resource and functionality losses. However, the comparison of technological alternatives may be difficult, and equal entropies do not necessarily correspond with equal recyclability. A coupling with energy consumption aspects is strongly recommended but largely lacking. The aim of this paper is to improve the multilevel SEA method to reliably assess the recyclability of plastics.

Plastics are the world's most widely used materials, largely due to their wide-spectrum use and relatively cheap manufacturing of complex shapes. Due to its properties, the use of plastics is possible in all manufacturing sectors. Important aspect of plastic moulding is that the heat passed to granulate is sufficient to properly heat up the plastic mixture. Another important factor is that the plastic mixture is blended as evenly as possible. Heterogeneities could lead to the formation of non-conformances with incorrect colour shades, unevenness of the mass or others. One of the factors that g

Consequently, this research aims at evaluating the factors that influence respondents’ decisions on managing their plastic waste and investigate respondents’ awareness of the health and safety issues associated with inappropriate plastic waste disposal. This research used a descriptive design. 360 individuals were randomly selected in three districts within the Cape Coast Metropolis. The data collection instrument was a structured questionnaire. The results showed that the influential

Abstract:

The problem of managing plastic waste is the focus of the entire world today. Mismanaged plastics make a significant contribution to the increase in carbon emissions as a result of the release of plastic chemicals that are exposed to sunlight or are burned. The plastics industry which continues to experience an increase in production makes plastic waste continue to increase from year to year. This study aims to determine the relationship of the effect of the amount of plastic production on increasing the amount of co2 emission carbon at the global level using a simple linear regression analysi

Abstract:

Over 5.5 million tons of plastic waste are generated globally from the research sectors. A university laboratory, e.g., pathology, can generate 250 tons of clinical plastic waste annually. The UK National Health Service (NHS) generates 133 kilotons (kt) of clinical plastic waste annually. Healthcare facilities in the US generate 1.7 million tons of clinical plastic waste annually. In addition, 95% of the clinical plastics are single-use plastics derived from fossil resources, i.e., crude oils. These single-use clinical plastic wastes are incinerated, contributing to global warming, or go to th

Abstract:

This paper simulates the plastic and biomass pyrolysis and ignition characteristics in different atmosphere, by thermogravimetric analysis polypropylene and plane wood at different oxygen concentrations. Experiments show that, increase the concentration of oxygen can accelerate the pyrolysis reaction rate of biomass and plastics, and can also reduce the ignition temperature of them. But for high volatile substances, such as plastic, the increase of oxygen concentration make a smaller effect on the pyrolysis and ignition, and for relatively high fixed carbon content substances, such as plane wo

Abstract:

The global energy demand is expected to increase by 30% within the next two decades. Plastic thermochemical recycling is a potential alternative to meet this tremendous demand because of its availability and high heating value. Polypropylene (PP) and polyethylene (PE) are considered in this study because of their substantial worldwide availability in the category of plastic wastes. Two cases were modeled to produce hydrogen from the waste plastics using Aspen Plus®. Case 1 is the base design containing three main processes (plastic gasification, syngas conversion, and acid gas removal), where

Abstract:

Few other environmental problems have received as much public attention and criticism in recent years as plastic pollution. Accordingly, in recent years, a number of plastic policies have been adopted at the national and supranational level in the EU and worldwide. In the U.S., health risks were repeatedly raised in the decision-making process of these policies and scholars have pointed out the crucial role of these arguments for the adoption of plastic policies. Hence, this article uses a structuring qualitative content analysis to investigate the parliamentary debates of two recently adopted
