Plastic revaluation value chain

Unlocking the hidden potential of plastics: Explore the plastic revaluation value chain and discover opportunities for SMEs.

Introduction

Plastic is a versatile and widely used material that has revolutionized the way we live, work, and play. However, the production and disposal of plastic also has significant environmental and social impacts. The plastic value chain is a complex and interconnected system that involves a wide range of actors, from fossil fuel companies to plastic product manufacturers, and from waste management companies to consumers. Plastic is made from fossil fuels, primarily crude oil and natural gas, which are extracted, transported to refineries and then converted into feedstocks for plastic production. These feedstocks are then transformed into polymer resin through a chemical process known as polymerization. This resin is then used to produce a wide range of plastic products, including packaging materials, consumer goods, and industrial products. Once the plastic products have reached the end of their useful life, they are either disposed of in landfills or recycled.

Understanding the different stages of the plastic value chain, as well as the opportunities and challenges associated with each stage, is essential for addressing the environmental and social impacts of plastic use.

Description

The plastic revaluation value chain consists of several stages, including raw material extraction, production, distribution, consumption, and end-of-life management. Each stage offers unique opportunities for revaluation and reuse, which contribute to a more sustainable future.

In Figure 1 the entire value chain of plastic is depicted and stages and substages can be found, along with some interesting data and the key players.

A detailed explanation of each step of the value chain is described below[1]:

  1. Raw Material Production:

– Raw Material: The raw material stage involves the extraction of petroleum or natural gas, which are the primary sources for most plastics. In recent years, the use of bio-based feedstocks, such as corn, sugarcane, and other plant materials, has gained attention as a more sustainable alternative to fossil-based resources.

– Monomer Production: In this stage, raw materials are processed into monomers, which are the basic building blocks of plastics. For example, ethylene, derived from petroleum or natural gas, is a common monomer used in the production of polyethylene.

– Polymer Production: Monomers are chemically bonded together in a process called polymerization to form long chains known as polymers. These polymers give plastics their unique properties, such as strength, flexibility, and durability.

– Plastic Conversion: During the conversion stage, polymers are transformed into various plastic products through processes such as extrusion, injection molding, blow molding, and thermoforming. Additives, like colorants, stabilizers, and fillers, may be incorporated to enhance specific properties or reduce production costs.

  1. Manufacture and Use:

– Production of Plastic Products: Manufacturers create finished plastic products by converting polymers into various shapes and forms. This process can involve assembling multiple plastic components, incorporating other materials like metal or glass, and applying coatings or surface treatments.

– Use: Plastic products are utilized in numerous applications, from packaging and consumer goods to automotive and construction materials. The use stage encompasses the functional life of the product, which can vary widely depending on the type of plastic and its intended purpose.

  1. Disposal and End of Life Treatment:

– Collection/Sorting and Recycling: Once plastic products reach the end of their useful life, they enter the waste stream. The collection and sorting stage involves separating different types of plastics by material, color, or other criteria to facilitate recycling. Mechanical recycling processes, such as shredding, washing, and pelletizing, convert plastic waste into secondary raw materials that can be used to produce new products. Advanced recycling technologies, like chemical recycling, can break down plastics into their original monomers, offering further opportunities for revaluation.

– End of Life: If plastics are not recycled, they may be subjected to other end-of-life treatments, such as landfilling or incineration. Landfilling involves disposing of plastic waste in designated facilities, where it can persist for hundreds of years due to its slow degradation rate. Incineration is the combustion of plastic waste, generating energy in the form of heat or electricity, but also releasing greenhouse gases and toxic emissions. A more sustainable alternative is the development of biodegradable plastics that can break down under specific environmental conditions, reducing the long-term impacts of plastic waste on ecosystems and human health.

Across the plastic value chain, there are many opportunities for SMEs to generate a real and effective change by reducing their environmental impact, increase competitiveness, and contribute to a circular economy. Figure 2 gives an overview of the value chain including the application of circular strategies by SMEs.
