As part of the initiative, the companies have worked with packaging firm Berry Global and recycling technology specialists Plastic Energy and Sabic.
Plastic Energy will convert soft plastic collected from Tesco stores into an optimal oil feedstock, which is then combined with virgin material to develop virgin, food-contact approved plastic pellets.
Berry Global will use the material to manufacture Heinz Beanz Snap Pots at its International Sustainability & Carbon Certification (ISCC) certified site.
Each pot will include 39% ISCC PLUS-certified recycled soft plastic content.
Heinz senior packaging development technologist Héloïse Carlier said: “We want our snap pots to be more sustainable while retaining the features that make them so popular with consumers: their convenience, handy snappable format, microwaveability and ensuring the product remains fresh.
“With this project and our introduction of the new Heinz Beanz Snap Pots, 22t of soft plastics will be recycled.”
Berry Global announced the partnership as part of its target to achieve 30% circular plastic use across its fast-moving consumer goods packaging by 2030.
Berry Global Consumer Packaging International Division president Jean-Marc Galvez said: “This is a prime example of an innovative advancement in circular packaging design made possible by collaboration across the entire value chain.
“This approach helps capture and reuse plastics that currently go unrecycled, to keep materials in use and out of our oceans and landfills.”
The project is intended to increase soft plastic recycling rates in the UK and across Europe.
Until 2020, only 6% of soft plastic in the UK was being recycled.
In September last year, Heinz partnered with US-based corrugated packaging company WestRock to launch an eco-friendly packaging solution for all its multipack canned products in the UK.
