Your Biocase's life cycle
We combine 100% plastic-free, biodegradable, and natural ingredients and mix them into a mold. Packaged in a 100% recyclable paper and eco-friendly ink.
Protect your phone and the environment
Biocase will protect and extend the lifetime of your device helping reduce impact on the environment. When the time comes to replace your BioCase, send it back to us and we will help it end its life in an eco-friendly manner.
Leave no trace
BioCase is designed to disappear Without harming mother earth. SKECH will take the case to a compostable environment were it will break down into tiny pieces to be returned back into the earth's soil.
About the Material
WHAT IS PBAT?
PBAT is incredibly biodegradable and will decompose in home compost leaving no toxic residues. It is currently partly derived from petrochemicals. PBAT has many attractive properties. For example, it has relatively high elongation at break (30 - 40%) as well as moderate high impact and puncture toughness, but only moderate tensile strength and low stiffness. Interestingly, it is PBAT that is added to make the product degrade quickly enough to meet the home compostability criteria. Unfortunately, when it comes to plant-based inputs there is a trade-off between renewability and compostability – the higher the % renewable, plant-based components the slower it is to compost! As an aside corn cobs, banana skins and avocado skins would not pass the AS5810 home compost test.
WHAT IS CALCIUM CARBONATE?
Calcium carbonate appears as white, odorless powder or colorless crystals. It is practically insoluble in water and is found extensively in rocks worls-wide. Ground calcium carbonate results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form. Precipitated calcium carbonate is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonisation or as a by-product of the Solvay process (which is used to make sodium carbonate).
