GreenGrip
Kitchen tools made from renewable raw materials
Under the GreenGrip brand, triangle combines products made from sustainable plastics.
Depending on the application, production method, and product type, different plastics with varying compositions are used. What they all share is a resource-conscious approach to nature and the use of renewable raw materials.
GreenGrip products are just as food-safe, dishwasher-safe, and durable as our conventionally manufactured kitchen tools.
GreenGrip Plastic for “Spirit” Kitchen Tools
The GreenGrip material used for the handles of the Spirit series is a 98% bio-based plastic containing 40% wood fibers. To produce this plastic, bio-propane is obtained from used cooking fats, which is then converted into a bio-polymer. In this way, even old frying oil finds a new, long-lasting purpose. The synthesis takes place in a refinery using the mass balance method.
The plastic is then blended with 40% wood fibers to increase volume and reduce plastic usage. This process takes place in southern Sweden, where the wood fibers are a by-product of the wood and paper industry. The resulting plastic granulate is then delivered to Germany, where it is processed into kitchen tool handles in Solingen.
The entire supply chain of our plastic is fully traceable and ISCC PLUS-certified (International Sustainability & Carbon Certification). The wood fibers used come from FSC-certified wood, and all raw materials and production steps are based in Europe, ensuring that no palm oil is used and transport distances remain short.
Overall, this process allows us to save around 80% CO₂ emissions compared to conventionally produced, petroleum-based plastics.
So, do you actually get a handle made from wood and old cooking oil?
(Not) quite yet.
Our GreenGrip bio-based plastic is produced using the mass balance method. This means that the refinery processes raw materials for both conventional, petroleum-based plastics and our cooking-oil-based plastics.
Keeping these two production streams completely separate would require either two distinct refineries or extensive cleaning of the same facility between production runs.
From both an economic and resource-efficiency standpoint, this separation currently doesn’t make sense — the share of bio-based plastics in total production is still relatively small.
For example, if a refinery processes 90,000 liters of crude oil and 10,000 liters of used cooking oil in a day, it produces 100,000 liters of mixed feedstock. According to the mass balance approach, 90% of the resulting material is sold as conventional plastic and 10% as bio-based plastic — much like the way green electricity is accounted for.
By using bio-based plastic, we increase demand for these more sustainable production methods and help boost the share of recycled, plant-based oils in plastic manufacturing.
The goal is for the demand for bio-based plastics to eventually grow large enough to make dedicated bio-refineries viable — and ultimately render the use of fossil resources unnecessary.
