GRAFE supplies masterbatch for biodegradable plastics from Golden Compound<\/h3>\n\n\n\n

Opinions are divided on coffee capsules. Some love the portioned enjoyment with its variety of aromas and flavours, others consider the small containers of palate pleasers to be cumbersome and overpriced. But studies show that the market for coffee on demand is growing almost unchecked. Proponents and opponents are united, however, in their criticism of the environmental compatibility of the mini-portions. Recyclability or even home compostability have so far not been among the features of the small packaging, which is nevertheless produced in large quantities.<\/strong><\/p>\n\n\n\n

Based on fibres from sunflower seed shells, maize starch and a rock flour mixture of mineral filler, Golden Compound GmbH, Ladbergen, has developed a bioplastic called \u201cSUN CIRLCE\u201d, from which the \u201cHOMEcap is made, which received the \u201cOK compost HOME\u201d certification from T\u00dcV-Austria in 2018 as a home-compostable disposable capsule. In its plain dark brown colour, it met all sustainability requirements, but not always the marketing aspects, where visual appeal is most important. Since 2016, Golden Compound has therefore been working with GRAFE, Blankenhain.<\/p>\n\n\n\n

In three years of development work, the colour specialists succeeded in developing masterbatches for colouring the coffee capsule, with which the small portions of enjoyment can be packaged in a visually appealing way without compromising compostability. In the meantime, nine colours have been certified by T\u00dcV Austria. \u201cThe development project was very complex and demanded our entire expertise in colouring plastics,\u201d reports Stefanie Theuerkauf, Sales Manager for the D-A-CH region at GRAFE. \u201cThe masterbatches may only contain certain ingredients, and the pigments can only be used in limited concentrations. In addition, it was a challenging task to overcolour the dark base material.\u201d <\/p>\n\n\n\n

From the modal range of the masterbatch specialist, the colours maroon, light grey, brilliant blue, blue grey, petrol brilliant, olive brilliant, violet brilliant as well as beige and berry are now available. The certification came into effect on 14 August 2020, and since then the colourful capsules have gradually entered the market. \u201cThe partnership with GRAFE also offers a lot of potential for us in the future,\u201d says Reinhard Trumme, authorised signatory at Golden Compound, and points to further durable or even home-compostable bioplastic products from his company.<\/p>\n\n\n\n

These include applications in the building industry, but also clothes hangers, urns, stacking boxes, coffee-to-go cups and, last but not least, the plant pot \u201cPOTTBURRI\u201d which became known to an audience of millions via the TV show \u201cDie H\u00f6hle der L\u00f6wen\u201d on the TV channel VOX. \u201cDue to sustainability, the market opportunities for such products are enormous,\u201d says Theuerkauf. \u201cThanks to our know-how in colouring plastics, these are increased even more, as colours are an important marketing tool to make products appealing.\u201d<\/p>\n\n\n\n

The disposable, home-compostable capsules have a flavour barrier, are Nespresso\u00ae compatible, heat-sealed and heat-stable. Manufactured by injection moulding on conventional machines, they have a low wall thickness of less than 500 micrometres. They thus build the bridge from economic efficiency to sustainability. Instead of being recycled as household waste, the capsules end up on the compost heap \u2013 and that is where they belong. Here, the coffee grounds provide valuable plant nutrients such as potassium, phosphorus and nitrogen. The material decomposes very quickly and completely at temperatures similar to those in garden soil or in a composter. So no CO2-intensive disposal and no energy-intensive heating.<\/p>\n\n\n\n

Compared to conventional aluminium capsules, PLA capsules or capsules containing hidden aluminium, SUN CIRCLE capsules offer advantages through home composting: \u201cIn contrast to these, not only water remains after decomposition. Our SUN CIRCLE raw material, including the sealing film on the coffee capsule, completely decomposes into water, CO2 and biomass within a year. It thus leaves behind humus and valuable fertiliser and, above all, no permanent microparticles,\u201d explains Trumme.<\/p>\n\n\n\n

Golden Compound produces two groups of materials: \u201cpro\u201d stands for durable, \u201cgreen\u201d for home-compostable. For this purpose, the company uses up to 70 per cent fibres from sunflower seed shells as filling and reinforcing material. These are a by-product of the food industry, come from an existing, quality-monitored supply chain and do not compete with food cultivation. \u201cIn addition, all materials have been optimised for the injection moulding process and offer good processability, stiffness or impact resistance,\u201d assures Annabelle Hoesen from Marketing\/Sales at Golden Compound. Further advantages are a possible reduction in cycle time as well as the unique look and feel.<\/p>\n\n\n\n

Various Golden Compound products have the \u201cOK compost HOME\u201d, \u201cOK compost INDUSTRIAL\u201d or \u201cOk biobased\u201d certificates. Environmentally conscious consumers should pay particular attention to the \u201cOk compost HOME\u201d label when buying their coffee capsules, because this confirms that the raw material already decomposes quickly at normal ambient temperatures in the garden soil or in the composter. In contrast, \u201cOK compost INDUSTRIAL\u201d means that temperatures above 50 degrees Celsius are required for decomposition. While 98 percent of all \u201cbiocapsules\u201d on the market only have this certificate, the \u201cHOMEcap\u201d has the very rare quality mark \u201cOK compost HOME\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
