Sustainable Practices in Plastics Industry
Plastics have played an indispensable role in modern life for decades, offering versatility, durability, and cost-effectiveness. In recent years, the industry has faced mounting pressure to address its environmental impact and embrace sustainability.

Turning sustainable in the plastics industry is not just a matter of corporate responsibility, but a strategic imperative for long-term survival and success.

As consumers and regulators demand more responsible practices, companies that fail to adapt, risk not only reputational damage but also potential legal and financial consequences. Embracing sustainability can lead to:


  • reduced costs,
  • enhanced brand value,
  • access to new markets, and
  • alignment with the growing eco-conscious consumer base

But how exactly do we embrace it? What are the different ways? What should you change?

To address these crucial questions, we asked our community what they thought was the best tactic for this transition to sustainable plastics via an online survey. With around 500 responses, it is clear that some options are starting to look more practical & applied in practice so that those sustainability goals look more realistic.

We know you want to decode these tactics too! So, let’s start exploring these.


Use Materials of Biobased Origin


Materials derived from renewable sources such as plants, algae, and even waste biomass, offer a promising avenue for reducing the environmental impact of plastic production. But how exactly you may ask? Here is how they can help you:

✓ Reduce your carbon footprint: Sources from which the materials are obtained absorb carbon dioxide from the atmosphere during their growth, helping to offset emissions generated during production. This means at the selection step itself, you can kick-start with your emissions reduction goals.

✓ Biodegradability and compostability: Although this characteristic is not true for all, those biobased materials that biodegrade, help mitigate the problem of plastic pollution, especially in single-use applications.

✓ Energy efficiency: Since the production of biobased plastics requires less energy vs. energy-intensive processes involved in extracting and refining fossil fuels. This also contributes to reduced GHG emissions.

✓ Diverse feedstocks: Since the range of feedstocks is vast such as agricultural residues, sugarcane, corn, etc., there is no dependency on specific crops or resources which can thus promote agricultural sustainability.

✓ Role in circular economy: Biobased plastics can be integrated into circular economy models, where products are designed to be reused, recycled, or repurposed. This helps keep materials in use for longer, reducing waste.

✓ Consumer awareness: Consumers are increasingly concerned about the environmental impact of plastics. Companies that use biobased materials in their products often appeal to eco-conscious consumers, enhancing brand reputation and market competitiveness.


How to claim sustainability for the use of biobased plastics?


LCALife cycle assessments (LCAs): LCAs can be used to compare the environmental impact of biobased plastics to that of petroleum-based plastics throughout their entire life cycle (production to disposal).


CertificationsThird-party certifications: There are a number of third-party certification organizations that can certify biobased plastics as being sustainable. These certifications typically require companies to meet certain criteria for feedstock production, manufacturing processes, and end-of-life management.


TransparencyTransparency: Companies should be transparent about the sustainability of their biobased plastics, including providing information about their feedstock sources, manufacturing processes, and end-of-life management plans.

✓ Extended producer responsibility (EPR): Embrace EPR programs that hold manufacturers responsible for the end-of-life management of their products, including recycling. With this, companies can design products with recyclability in mind.

✓ Certification and transparency: Seek certification from relevant sustainability organizations to verify that your products and practices adhere to recycling and eco-friendly standards. Transparency in recycling efforts builds trust with consumers.

✓ Innovation in recycling technologies: Invest in research and development to improve recycling technologies, including the ability to recycle more types of plastics, like mixed plastics or multi-layer packaging. Check out the latest industry news on recycling.


Use Materials of Recycled Origin


When it comes to an ultimate solution for the ‘plastics pollution problem’, recycled plastics can be the answer! They are appealing to eco-conscious consumers, foster innovation, and increase supply chain resilience. This is the third option to demonstrate commitment to sustainability.


How about the performance of recycled vs. virgin plastics?


New recycling technologies are being developed that can produce recycled plastic with properties that are closer to those of virgin plastic. For example, some new recycling technologies can remove contaminants from plastic waste more effectively and can produce recycled plastic with a higher molecular weight.

Another way is using additives to improve the performance of recycled plastics. For example, some additives can improve certain characteristics of recycled plastics, like strength, durability, and heat resistance. Let’s go through the ways now to claim sustainability through the use of recycled plastics:

✓ Resource conservation: Utilizing recycled plastics reduces the demand for virgin plastic production, conserving valuable fossil fuel resources and promoting a more sustainable approach to material sourcing.

✓ Energy efficiency: Recycling plastic typically requires less energy than producing new plastic from raw materials, resulting in reduced carbon emissions and a smaller environmental footprint.

✓ Waste reduction: Incorporating recycled plastics into products diverts plastic waste from landfills and incineration, contributing to waste reduction and alleviating the environmental burden of plastic pollution. Read how to reduce plastic waste.

While not wishing to allow "Perfect to be the enemy of better", I believe the above article falls short of the circularity mark. Nothing seriously wrong with the individual elements of the concept, although anything that doesn't have total elimination of fossil resources as the end game, is flawed, and e.g. using a fossil based chemical like maleic anhydride to rebuild the molecular weight of polymers for recycling, where prior mechanical recycling is one of the factors causing the molecular weight loss, represents a gap in the circle. If plastics, meaning all plastics, are to become at least as recyclable as glass or metals, that can only be achieved via an energy efficient form of chemical recycling that can take all plastic waste the mechanical recycling industry can't or won't recycle. It needs to be capable of chemically recycling unclassified mixed waste plastics and produce a stable plastic crude oil at high yield, that can be stored and transported. Pyrolysis can't do those things, and geographies with no polymerisation industry, need access to such chemical recycling to be able to ship their plastic crude oil to be re-polymerised into virgin plastics. The total existing inventory of plastics in use and post use, in or on land, and in the oceans, plus renewable biological or greenhouse gas based feedstocks should be more than capable of meeting demand growth for the foreseeable future. Such a technology may be closer than you think. Keep an eye on the MURA development in Wilton UK.
