Are your phone cases carbon neutral?
Yes, the phone cases are carbon neutral. We are trying to emit as little CO2 as possible. The rest we compensate with our climate partners. The phone case has a carbon footprint of approx. 167 g of carbon dioxide equivalents per case during its whole lives. This includes everything from raw materials, production to shipping and recycling.
We do not only compensate the footprint of a case, but 1 kg, because the more the merrier!
Additionally, for every case sold we donate a part of our revenue to social and environmental nonprofits all over the world.

Are the cases 100% biobased?
Our material is a proprietary, environmentally sustainable formulation containing organic substances and to a small portion natural minerals.
The organic substances (read materials based on carbon) are mainly made up of two parts: a base biopolymer which keeps everything together and organic residues, which give your case its unique and smooth texture as well as the necessary strength to protect your phone. The organic residues are for example agricultural by-products, valuable natural resources that we keep in the loop to support circular economy.
The base biopolymer is DIN Certified for a “50% – 85% biobased carbon content” and the organic residues are 100% biobased. The minerals are of natural origin and essentially stone dust.
The coloring pigments are partly natural, partly synthetic. Of course they are non toxic and the material stays biodegradable also under home-composting conditions.
We are constantly working to increase the biobased content of our material.
How long does it take for my kepu case to compost in my garden composter?
Our material is certified to compost under industrial conditions according to EN 13432 (09-2000). This means 90% will be composted within 90 days in an industrial composting environment.
Home composting is also possible but will take longer. It is hard to tell how long, as it heavily depends on the conditions, such as temperature and moisture, and the quality of the composting environment. A composting time of several months or even 2 years is possible. A good rule of thumb is to look at how long a similar object made of wood would take to compost. We are currently conducting research in our own composters.
What to do with my old kepu case?
These are the three best options in our opinion.
Sending it back: you are encouraged to send your case back to us. We will recycle it and make new cases out of it. This is the best option since shipping it back causes way less carbon emissions compared to making completely new material. Additionally, this closes the material loop, so we can help build towards a true circular economy together.
Composting: composting will only leave biomass, water, minerals and CO2 behind - no harmful substances or microplastic. You can compost your case at home. Give it some time (2-3 years). Just like a comparable product made out of solid wood, your phone case won’t compost overnight. Industrial composting works as well, however please check with your local waste management first, if bioplastics are allowed in your compost bin.
Disposal by incineration: This option might come to a surprise to you, as it is known for downcycling materials. However, as recycling of bioplastics is not yet supported on an industrial level (That's why we do it ourselves, when you send your old case back to us) it is a viable option. If sending back or composting is not an option for you, you can dispose of your phone case via residual waste to incineration. The incineration does release carbon dioxide, but only the amount, that was taken out of the atmosphere by the plants we used for our materials. Plus, the energy generated by the burning replaces the need of fossil fuels.
Side note: In a landfill the phone case will most likely not biodegrade, but remain intact. For bioplastics to biodegrade, certain conditions are necessary, which are usually not met in a landfill.
Where do you make the cases?
We develop the material, produce our prototypes and develop the cases in our office in Darmstadt, a city a bit south of Frankfurt, Germany. The serial production of the cases is done by a partner a few kilometers from our office.
kepu cases are made in Germany under the highest quality, environmental and safety standards.
What is your social and environmental impact?
We strive to reduce our environmental impact wherever possible. We compensate our CO2 footprint (and more). Additionally we donate to environmental and social nonprofits that tackle problems, that still arise because of phones and phone cases world wide. We live and create for a better world.

Is your packaging recyclable?
Sustainable products need a sustainable packaging! That's why we designed the packaging so it can be fully recycled in the paper cycle. The cardboard is even made of 100% recycled paper! This way we close the material cycle. Help us by giving the packaging to paper recycling.
