Recyclable by Design

Sulapac materials are designed to be recycled either mechanically or chemically. Once a product can no longer be reused or repurposed, recycling is the recommended end-of-life option for our materials. And, recycling biobased biodegradable materials in general, is the key to truly sustainable circular bioeconomy. So, let’s dig deeper into the topic!

Most Sulapac materials can be recycled in a so called polymer-to-polymer process, where polymers are broken down back to monomers via hydrolysis. Those monomers  are then used as building blocks for new biopolymers. This process has numerous benefits: the yields are high, energy consumption low, and most importantly, the quality and purity of the recycled material is the same as for virgin material.

Plastic waste stream or separate collection?

Field tests have also verified that Sulapac materials can be collected and sorted out of a mixed waste stream. When collected together, Sulapac materials do not interfere with the current mechanical recycling of conventional fossil-based or bio-based non-biodegradable plastics. Hence, you can safely discard a Sulapac product by putting it into the plastic waste bin.

Does it get recycled then? The answer is “Today, no. In the future, most likely yes.” The technology exists and is already in use across Europe. However, the collection, sorting and recycling infrastructure needed to achieve recyclability at scale is still in its early stage. Various instances, including ourselves, are pushing hard to accelerate the development in the EU. Read more about the topic here.

While the universal collection, sorting and recycling infra is still underway, recycling Sulapac in closed loop systems is feasible right now. In fact, our customers cups made of Sulapac Solid are being processed in a recycling facility in Belgium as we speak.

Certified for Industrial Composting

In some cases composting can also be a feasible end-of-life option for Sulapac packaging or products. All Sulapac materials have been certified as industrially compostable according to EN 13432 or ASTM D6400 and posses either Seedling, BPI or OK Compost certificates.

The outcomes of industrial composting process are CO2, water and compost. The compost includes nutrients, and can be used, for example, in agriculture to enhance the quality of soil.
