Can cap made from recycled plastic (PCR)
TUNAP is continuously working on concepts to make the ingredients, packaging and use of its products more sustainable. We are now taking another important step towards sustainability: from 2022, we will be replacing all TUNAP own-brand and private-brand can caps with sustainable PCR caps. PCR stands for Post Consumer Recycling and identifies materials that have been made from recycled plastics.
By using PCR can caps, we save 22 tonnes of new plastic every year, which is equivalent to the weight of 18 compact cars. We also save a further 23 tonnes of CO₂.

Post-consumer recycling
The recycling of plastic waste and the saving of new plastic is a central component of the TUNAP mission. Our PCR (post-consumer recycled) caps are made from recycled plastic from discarded materials collected from household or commercial waste. TUNAP thus makes a lasting contribution to the circular economy.
Grey is the new green
In contrast to grey plastics, black plastics can only be recycled to a limited extent: black is not recognised in conventional sorting systems and therefore cannot be recycled - at least when separated using NIRS technology (near-infrared spectroscopy). TUNAP has therefore decided to introduce the grey cap. By using grey PCR granulate, we ensure recyclability: at TUNAP, grey is the new green!
From recyclate to granulate
Post-consumer waste from households or businesses is collected for the production of PCR plastic. This material is the starting product of the recycling process and is known as recyclate. It is sorted, cleaned, heated and finally ground into granulate, which is used to produce the PCR caps.
Colourful becomes grey
The mixture of shredded plastic flakes that make up the PCR recyclate is colourful. Melting it down and converting it into PCR granulate ultimately produces the grey colour - similar to recycled paper, which was initially usually greyish in colour. By using the grey PCR caps without additional colouring, TUNAP can save further resources.
From granulate to the finished product
The granulate made from recycled plastics is grey and forms the basis for the injection moulding process that brings the material into the desired shape.
The granulate melts in the injection moulding process and is injected into a mould under high pressure, creating the grey can cap.
Our new PCR can caps are used in Private Brand products and under TUNAP's own brand, for example in the 115 Universal Cleaner.
