“…This is the conventional waste management approach [7,[100][101][102]. Studies report municipal solid waste (MSW) generation would rise from 2.4 billion tonnes in 2018 up to 2.6 by the year 2025 [103].…”

An Overview of Plastic Waste Generation and Management in Food Packaging Industries

Over the years, the world was not paying strict attention to the impact of rapid growth in plastic use. This has led to unprecedented amounts of mixed types of plastic waste entering the environment unmanaged. Packaging plastics account for half of the global total plastic waste. This paper seeks to give an overview of the use, disposal, and regulation of food packaging plastics. Demand for food packaging is on the rise as a result of increasing global demand for food due to population growth. Most of the food packaging are used on-the-go and are single use plastics that are disposed of within a short space of time. The bulk of this plastic waste has found its way into the environment contaminating land, water and the food chain. The food industry is encouraged to reduce, reuse and recycle packaging materials. A wholistic approach to waste management will need to involve all stakeholders working to achieve a circular economy. A robust approach to prevent pollution today rather than handling the waste in the future should be adopted especially in Africa where there is high population growth.

“…Additionally, incineration of waste results in volume reduction of up to 99% and the residue can then be landfilled. Care must be taken as some air pollutants are emitted during incineration which include greenhouse gases and carcinogenic substances [6,100,123,124].…”

“…Few research efforts were made to investigate recycled plastics as ordinary Portland cement (OPC) replacement, especially when compared to substitution of aggregates or fiber reinforcement. Despite the potential to significantly reduce the embodied energy of concrete and mortar, this review identified only six research outputs on the subject published since 2009 [49][50][51][52][53][54]. This is likely due to the non-cementitious nature of plastic particles which, when mixed with cement paste, have adverse effects on mechanical behavior and compressive strength [49,50].…”

Current Sustainable Trends of Using Waste Materials in Concrete—A Decade Review

et al. 2020

Concrete is the most used construction material in the world. Consequently, the mass extraction of virgin materials required for concrete production causes major environmental impacts. With a focus on promoting sustainability, numerous research studies on incorporating waste materials to replace virgin substances in concrete were undertaken. Despite this vast volume of published literature, systematic research studies on these sustainable concrete mixes that inform various stakeholders on current research trends, future research directions, and marketability options products are seldom conducted. This paper presents a decade review on sustainable concrete with a focus on virgin materials being replaced with waste materials. It aims to inform researchers of current research trends and gaps in the research area of waste material use in concrete. The review also identifies key parameters that restrict the marketability of these sustainable concrete products. The three-step research methodology involves a bibliometric assessment, a key review of selected waste materials, and an interview with a panel of experts focusing on impediments towards the transition of sustainable concrete products into the industry market. Bibliometric assessment was based on 1465 research publications in which five key materials (plastic, glass, fly ash, slag) and construction and demolition waste were selected for the review. The interview was conducted with ten industry experts to discuss the industry limitations in the commercial establishment of materials. The review of existing knowledge and the findings on sustainable concrete presented in this paper provide directions for both research academics and industry stakeholders to systematically focus on sustainable concrete products that are market-ready.

“…Waste plastic materials may be used as a binding material for making of paving blocks capable of supporting low loadbearing purposes such as walkways, footpaths, building premises among others in highly moist environments due to their low water absorption capacity. However, the potential practical implications of using the recycled plastic waste in paving blocks making in the municipality would heavily depend on 4A's (acceptability, accessibility, adaptability and affordability) concept of marketing this new product [9].…”

The global plastic production increased over years due to the vast applications of plastics in many sectors such as packaging, electrical and electronics, household, automotive, construction, agriculture and other sub-sectors (medical devices, plastic furniture and toys). The scope of this study is focusing on recycled high-density polyethylene (HDPE) such as detergent bottles to be compress in mould after reach its suitable melting point and subsequent effects of temperature by using pyrolysis method. Since polyethylene makes up the largest percentage of plastic produced globally, and has the potential to be recycled indefinitely, it makes an excellent starting point for mitigating the severe impacts plastic waste has on the global environment. Recycled HDPE is an incredible material for the entrepreneur, as it can be recycled indefinitely, using common household tools and appliances. The unique properties of HDPE result from the strong and rigid linear molecular structures that make up the material. The continuous demand of plastics caused the plastic waste accumulation in the landfill consumed a lot of spaces that contributed to the environmental problem. The ranking of the highest to the lowest plastic waste in municipal solid waste according to the categories of plastic containers. Plastic waste issue has been discussed from time to time. This issue is getting bigger when burning of plastic in the open air, leads to environmental pollution due to the release of poisonous chemicals. The polluted air when inhaled by humans and animals affect their health and can cause respiratory problems. The main objective of this study is to determine the melting point and subsequent effects of temperature on recycled HDPE through pyrolysis method.
