Plastic pollution presents an urgent environmental crisis, yet outright bans on plastic materials are impractical given their widespread utility. Addressing the challenge requires scientific advancements alongside coordinated global strategies and economic models designed to minimise waste streams. Achieving total recycling remains unrealistic whilst most plastics are composed of multiple polymers rather than single polymers. Furthermore, biodegradable alternatives do not yet offer an effective remedy, as they remain costly, face engineering constraints relative to conventional petroleum-based plastics, and demand specific environmental conditions to degrade properly. Comprehensive research into microplastics is also essential to track their sources, environmental dispersion, and toxicological mechanisms. Because current technologies and intervention strategies fail to resolve the problem adequately, adopting waste management priorities that emphasise reducing consumption and reusing existing plastic goods offers the most effective immediate path forward.
Plastic waste accumulates globally, yet simple bans or current recycling systems cannot keep pace with production. Understanding the technical limitations of multi-polymer materials and biodegradable substitutes helps industry leaders and policymakers focus resources on practical interventions. Prioritising reduction and reuse prevents waste generation directly, mitigating microplastic proliferation and environmental contamination while sustainable polymer technologies mature.
The abstract does not indicate a direct commercialisation pathway or specific proprietary technology. Instead, it highlights critical industrial design constraints for product developers and recyclers, particularly the need for single-polymer products to enable recycling viability. Manufacturers developing biodegradable alternatives face clear technical hurdles in cost, engineering performance, and degradation requirements before achieving broader market readiness.

The pollution of the environment by plastics is a global problem that is real and needs to be resolved urgently. The authors argue that banning the use of plastic is not a reasonable and rational solution for the problem because plastics have many useful applications. Solutions to the problem must involve developing scientific approaches as well as global efforts and strategies. The world’s approach needs to be guided by an economic model that eliminates or minimizes the amount of plastics in the waste stream. As long as most plastic materials are not made from a single polymer, then the idea of “recycling 100% of plastics” is so far an unrealistic solution. The development of biodegradable plastics is still far from being an effective solution because besides being expensive and having limitations in engineering applications when compared to petroleum-based ones, biodegradable plastics still require specific conditions for their biodegradation. Comprehensive studies on microplastic particles are needed, focusing mainly on the source of the particles, their distribution, transport, fate in different environments, and toxicological effects and mechanisms. Since plastic pollution is a global problem, its minimization will require an increased international cooperation platform and partnerships at a global level. While current technologies and strategies are not solving the environmental problem caused by waste plastic, the most effective solution would be to adopt the first two levels of the waste management hierarchy, which are “reduce” and “reuse”.
