The ND re-GROW sedum cassette are made from 100% regrowing materials. PLA (Polylactic acid) and Miscanthus are the raw materials used. Whereas traditional plastics use polymers based on oil or gas, PLA uses polymers based on renewable resources.

Upcycling: waste as a raw material
The PLA that is used for the ND re-GROW Sedum Cassette is made from potato peelings and corn that come from the waste streams of human and animal food production. Miscanthus Giganthus grows over 3 meters per year and stores CO2 while growing. The crop does not need to be fertilized or chemically sprayed and grows on plots that are not suitable for food.

The ND re-GROW Sedum cassettes are suitable for postconsumer recycling, granulation for use as a substrate or for industrial composting. This makes a green roof even greener than it already is.

The technology behind the re-GROW cassette
In the technical implementation of green roofs, the focus should always be on using as little plastic as possible. That is why Nophadrain was committed making the ND re-GROW Sedum Cassette thin walled, but still robust. The challenge here was to find a raw material that combines a low viscosity with a suitable MFI (Melt Flow Index) for the mold injection molding process. The mixture of PLA and Miscanthus that Nophadrain uses in the ND re-GROW Sedum Cassettes has been specially developed for this purpose. It is the first time a strong sedum cassette was made with PLA.
