What is Biological Recycling?
Overview of Biological Recycling
Biological recycling, or biorecycling, is a process that uses natural organisms to break down plastics into reusable materials. Unlike traditional recycling methods, which often involve mechanical or chemical processes, biorecycling relies on microorganisms such as bacteria and fungi. These organisms metabolize plastics, converting them into substances that can be reintegrated into the environment or used as raw materials.
Role of Microorganisms in Degradation
Microorganisms play a crucial role in Mechanical Recycling. They possess enzymes that can break down complex plastic polymers into simpler compounds. This process not only reduces plastic waste but also produces byproducts like compost or biogas, which can be harnessed for energy. By leveraging the natural abilities of these microorganisms, we can turn waste into wealth.
For instance, certain bacteria can digest polylactic acid (PLA), a common biodegradable plastic, breaking it down into lactic acid. This lactic acid can then be used to produce new plastics, closing the loop and supporting a circular economy.

Difference from Mechanical Recycling
Mechanical recycling involves shredding, melting, and reforming plastics into new products. While effective, this method can degrade the quality of plastics over time, limiting their reuse. In contrast, biorecycling maintains the integrity of plastic materials, allowing them to be reused indefinitely without losing their properties. This not only conserves resources but also reduces the environmental footprint of plastic production.

Types of Biorecycling Techniques
Composting and Its Benefits
Composting is a well-known biorecycling technique that involves the breakdown of organic waste by microorganisms. When applied to biodegradable plastics, composting transforms them into nutrient-rich compost, which can enhance soil fertility. This process not only reduces landfill waste but also supports sustainable agriculture by providing natural fertilizers.
Composting is particularly effective for plastics labeled as “compostable,” which are designed to break down under specific conditions. By composting these materials, we can divert waste from landfills and contribute to a healthier planet.

Anaerobic Degradation and Biogas Production
Anaerobic degradation is another powerful biorecycling technique. This process involves breaking down biodegradable materials in the absence of oxygen. During anaerobic digestion, microorganisms decompose organic waste, including certain plastics, producing biogas as a byproduct. Biogas, rich in methane, can be used as a renewable energy source, providing heat or electricity.
This method not only helps manage waste effectively but also contributes to energy production. Anaerobic digestion facilities can be integrated with existing waste management systems, enhancing their efficiency and sustainability. By converting waste into energy, we reduce our reliance on fossil fuels, contributing to a cleaner and greener environment.

Enzymatic Recycling: A Sustainable Option
Enzymatic recycling stands out as an innovative and sustainable biorecycling approach. Unlike other methods, it uses specific enzymes to break down plastics at a molecular level. These enzymes target the bonds in plastic polymers, converting them into their original monomers. This process allows for the complete recovery of raw materials, which can be used to create new plastics.
Enzymatic recycling is particularly advantageous because it operates at lower temperatures compared to traditional recycling methods, saving energy and reducing emissions. It also offers the potential to recycle mixed or contaminated plastics, which are often challenging to process through conventional means. As research advances, enzymatic recycling could revolutionize the way we handle plastic waste.
Plastics Suitable for Biorecycling
Not all plastics are suitable for biorecycling. The effectiveness of biological recycling depends largely on the type of plastic and its biodegradability. Generally, plastics that are labeled as biodegradable or compostable are ideal candidates for biorecycling processes. These materials are designed to break down more easily in natural environments, facilitating their conversion into valuable resources.
Biodegradable plastics, such as PLA and polyhydroxyalkanoates (PHA), are derived from renewable sources like corn starch or sugarcane. They are engineered to decompose through microbial action, leaving behind no toxic residues. These plastics are perfect for composting and anaerobic digestion, offering a sustainable alternative to traditional petroleum-based plastics.
However, it’s important to note that biodegradable does not mean the same as compostable. While all compostable plastics are biodegradable, not all biodegradable plastics meet the standards required for composting. Compostable plastics must break down within a specific timeframe and environment, producing nutrient-rich compost as a result.

Biodegradable vs. Compostable Plastics
The distinction between biodegradable and compostable plastics is crucial in understanding their role in biorecycling. Biodegradable plastics can decompose through natural processes, but the time and conditions required can vary widely. Compostable plastics, on the other hand, are designed to break down within a set period, under controlled composting conditions. For those interested in sustainable practices, exploring eco-friendly zero waste kits can be a great way to reduce plastic waste.
For example, a compostable plastic bag might decompose completely in a commercial composting facility within 90 days, turning into compost that enriches the soil. In contrast, a biodegradable plastic might take years to degrade in a landfill, depending on environmental factors.
