The Material Effect
From waste to breakthrough materials: Let's tackle the untapped potential of bio-waste and post-consumer plastics. Uniting performance with sustainability. Offering LCA data and third-party certified materials. Recycling solutions for your circular journey.
Setting a new benchmark for power, more sustainability, and eco-consciousness, Bayblend® RE combines high flame retardancy with claimable environmental benefits.
More sustainable power for flame-retardant cell-holders
Instagrid (opens in a new tab), a newcomer in the area of high-power portable battery station, known for its commitment to innovation, design and sustainability, aimed to enhance the advanced portable battery module.
The task was not only to revolutionize energy conversion technology and make the Instagrid battery station smaller, lighter and more powerful, but also to reduce the environmental impact of the end product by using more sustainable and efficient material solutions.
Portable power with reduced carbon footprint
Covestro and Instagrid conducted tests together to find a more sustainable material solution which reduces the carbon footprint of the portable power station and at the same time is flame retardant for increased safety. The suitable material solution should not only meet stringent high-performance and reliability in power, but also incorporates a sustainable answer to a reduced carbon footprint of the portable power station.
“By using the Instagrid portable power station you achieve instant Power with Lasting Impact more sustainable than ever before.”
Steffen Becker
Product Owner, Instagrid GmbH
Bayblend® RE for more sustainability and power
By using Bayblend® RE from Covestro, Instagrid demonstrates how carbon emissions can be effectively reduced (2/3 less CO2 eq. / kg) in portable energy systems such as battery modules also in the built-phase. Instagrid stands for pure performance in terms of energy conversion technology and has become a beacon for more sustainable solutions. As a pioneer, Instagrid inspires industry peers to embrace environmental responsibility without compromising on quality or design.
The tests yielded, that the optimized production volumes and reduced environmental impact processes of the new material, Instagrid has achieved a remarkable reduction in equivalent CO2 emissions by more than 65%*.
"We are delighted to see how newcomers to the industry pioneering sustainability with their products are, combining performance and safety while offering demonstrable environmental benefits. Together we are shaping a more sustainable future."
