with a low carbon footprint on your filter aid.
thanks to the amorpheus characteristics of perlite.
because of the low density of perlite
Leave the lowest possible carbon footprint with our filter aids and possibly re-use the perlite again as a soil improvement mineral and carrier for organic matter as fertilizer.
Perlite is basically a rock which came from nature and can return to nature after use. It is approved for soil improvement and many of our customers have found a local farmer who can use the used filter aid on his lands.
If the solids left in the filter medium is an organic material it can serve as organic fertilizer on the field.
Perlite is amorphous and it does not damage lung tissue the way crystalline products can. The MSDS presents no hazards to human health.
However, as with all dust particles, precautions such as wearing a dust-mask are advised when handling the product.
The heat we use at Nordisk Perlite is re-distributed for district heating. By expanding the raw material 10-20 times, we obtain a high product yield.
We have 100 % use of our raw perlite, so nothing goes to waste. All of these process features allow us to keep the carbon footprint lower than competition.
In many cases our products are used for another purpose after their first usage, which adds to your sustainability agenda and a circular economy.
