New convenient and compostable waste bags have hit German retail stores 

Frankenthal, Germany-based RKW has launched a biodegradable star-sealed bag for organic household waste in Germany. Certified as fully compostable by DIN Certco, it is also the first T-shirt star-sealed bag available on the market made from more than 50 percent renewable - corn-derived starch and polylactic acid (PLA) - material.

For family-owned film manufacturer RKW, sustainability is an integral part of its business mission, and this includes the use of biodegradable or biobased films. RKW Vietnam, which is specialized in consumer packaging, produces the compostable bags in Ho Chi Minh City.
Star-sealed, the new bag is created without gussets and sealed in a single spot, making it highly practical and virtually leak-proof.
For organic waste, many people use paper bags, which, while fully biodegradable, tend to become soggy and tear easily when taken out of the bin. The bags come with carrying handles that can be used to tie them shut, and the star-sealed bottom that consumers are familiar with from conventional plastic-based trash bags. Fully compostable and hence suited for organic waste, the bags will be supplied by major retailers.
“RKW is a pioneer on the market,” says Manh-Hung Ngo, Product Manager at RKW Vietnam. “So far, bags with up to 40 percent renewable content have been available in markets such as France or Italy. We were able to design bags with a significant higher proportion. Hence, these waste bags are another milestone towards a more sustainable future.” The bag is fully compostable and certified to European standard EN13432 by the DIN Certco institute in Berlin (Germany).
The bag is suited for bins with different shapes and prevents the leakage of liquids. Multiple layers strengthen the bottom, avoiding damage to the bag. Combining the practical features with benefits in terms of sustainability, the new bags are a more environmentally friendly and a convenient option for consumers.
