A guide to recycling plastic effectively

Discover the benefits of recycling plastic effectively, including how doing so helps the environment, and how Riverdale can provide support.

Plastic is an integral part of our modern lives, offering excellent convenience and durability in a vast array of applications. From the essential packaging that keeps our food fresh and safe, to the durable materials used in construction and healthcare, plastic’s versatility is truly remarkable.

However, despite these numerous benefits, the very properties that make plastic so useful, its durability and slow degradation, contribute to its significant persistence in the environment, posing a growing ecological challenge.

This is why understanding the importance and multifaceted benefits of plastic recycling is absolutely crucial for forging a more sustainable future. At Riverdale Recycling, we firmly believe in the power of responsible waste management, and that effectively recycling plastic stands as a cornerstone of this commitment.

Why is it important that we recycle plastic?

The necessity of plastic recycling stems from several critical environmental and resource-related factors. Here we will explore some of the key reasons why recycling plastic is so important.

Reduction of energy consumption

Manufacturing new plastic from raw materials is an energy-intensive process. Recycling plastic significantly reduces the energy required for production, as the existing material is repurposed rather than starting from scratch. This conservation of energy helps lower our overall carbon footprint and reduces the strain on our energy infrastructure.

Preserving fossil fuels

Virgin plastic production relies heavily on fossil fuels like oil and natural gas. By recycling plastic, we decrease our dependence on these finite resources, helping to conserve them for future generations and reduce the environmental impact associated with their extraction and processing, which can include habitat destruction and pollution.

Lowering emissions

The production of new plastic releases greenhouse gases into the atmosphere, contributing to climate change. Recycling plastic requires less energy, leading to a substantial reduction in these harmful emissions. By choosing to recycle, we actively contribute to cleaner air and a healthier planet for ourselves and future generations.

Minimising solid waste going to landfill

Plastic is notoriously slow to degrade in landfill sites, taking hundreds, if not thousands, of years to break down. This leads to a continuous accumulation of waste, taking up valuable land and potentially leaching harmful chemicals into the soil and groundwater. Recycling diverts plastic away from landfills, reducing this environmental burden.

Protecting wildlife and ecosystems

Plastic pollution poses a significant threat to wildlife, both on land and in our oceans. Animals can ingest plastic debris, mistaking it for food, leading to starvation and internal injuries.

They can also become entangled in plastic waste, causing suffocation or restricting their movement.

By recycling plastic, we reduce the amount of plastic entering the environment, helping to safeguard vulnerable ecosystems and the creatures that inhabit them.

How is plastic recycled?

The journey of a discarded plastic item to a new product involves a systematic recycling process. Here, we will explore the two-step process that sees plastic go from being discarded waste to new products.

Stage 1: Collection and sorting

The initial stage focuses on preparing the collected plastic for reprocessing. This begins with sorting by polymer type, a largely automated process that ensures compatibility for later melting.
Following the automated sort, a critical manual inspection takes place to meticulously remove any remaining contaminants, such as non-plastic items, labels, and residual materials. Once sorted and thoroughly cleaned, the plastic is ready for its physical transformation.

Stage 2: Forming new products

The second stage involves converting the prepared plastic into a usable form for manufacturing new items. Cleaned plastic can be processed in one of two primary ways at this point. It is either shredded into flakes, which increases its surface area for more efficient melting, or it can be directly melt processed.

Regardless of whether it’s in flake or molten form, the plastic is ultimately transformed into small, uniform pellets. These pellets then become the raw material that manufacturers can use to mould and create a wide array of new plastic products, giving discarded plastic a second life.

Which plastics can be recycled?

While recycling infrastructure and local council capabilities can vary across the United Kingdom, some plastic types are more readily and commonly recycled. These include:

  • PET (Polyethylene Terephthalate): Widely recycled and commonly found in clear drinks bottles (like water and fizzy drinks), food containers (such as salad trays), and some other types of packaging.
  • HDPE (High-Density Polyethylene): Another frequently recycled plastic, typically used for more rigid containers like milk jugs, detergent and household cleaner bottles, shampoo and conditioner bottles and even some types of pipes.
  • LDPE (Low-Density Polyethylene): This is where things become more complex. While clean LDPE products such as bread bags, pill bottles and bin bags can technically be recycled, very little of it ends up being recycled as demand is currently so low.
  • PP (Polypropylene): The same is true of cleaned PP products such as food containers and clothes hangers. The primary concern here is that the quality of the polymer will be significantly degraded by the mechanical recycling process.

Some common plastics that often pose challenges and are therefore slightly more difficult to recycle in most kerbside collections include:

  • PVC (Polyvinyl Chloride): Often found in items like pipes, window frames, blister packaging, and some types of cling film. Its chemical composition can make this less compatible with typical recycling processes.
  • Polystyrene (PS): Commonly used in foam packaging (including takeaway food containers and protective packaging like Styrofoam), disposable cutlery, and some yogurt pots. It is often bulky and can be difficult to process efficiently, though it is worth noting that this can be recycled with the correct recycling infrastructure.
  • Other: With examples including PLA (Polylactic Acid) and PC (Polycarbonate), items such as water jugs for cooling towers, reusable drinks bottles and other bio plastics are difficult to recycle due to the additives that make them compostables, as these can clog recycling systems. However, as with PVC and PS can be recycled at the correct facility.

How to navigate recycling plastic at home vs recycling plastic at a facility

Understanding where and how to recycle different types of plastic is key to effective waste management.

Recycling plastic at home

Your local council often provides kerbside collection for commonly recycled plastics like PET and HDPE bottles and containers. Ensure these items are empty, clean, and dry before placing them in your designated recycling bin. Remove lids and pumps where possible.

Recycling plastic at a facility or designated collection points

Certain plastic types, such as flexible plastics (like crisp packets and carrier bags), PVC, and polystyrene, are generally not accepted in standard household recycling.

However, dedicated recycling facilities or specific collection points (often found at supermarkets or community centres) may accept these materials. Always check with your local council or these facilities for their specific guidelines on accepted plastic types and how to prepare them.

How can Riverdale Recycling help?
