Evaluation of marketing prospects for a green silica filler
Brisil Technologies and Lehmann & Voss & Co. have signed an agreement to evaluate the commercialisation prospects of a silica filler derived from biomass. The evaluation relates to elastomer applications and is limited to Europe.
The silica filler is “precipitated silica”, which Brisil extracts from rice husk ash using a residue-optimised chemical process. The process was developed by Brisil and has already been patented.
Rice husk ash is produced during the combustion of rice husks. Brisil obtains this ash in close cooperation with companies that carry out the thermal utilisation of the rice husks. This creates a classic win-win situation, as the companies have a responsibility to dispose of their “biological waste” in an environmentally sound manner due to stricter environmental standards.
Filler in paints, coatings and plastics
The precipitated “green” silica is used as a filler in paints, coatings and plastics, among other things. Currently, there is a production plant in the Indian state of Gujarat with a capacity of 7,400 tonnes per year. Further production facilities in Asia are in the planning stage.
“Brisil is tackling one of the global problems of sustainable waste recycling. Due to their innovation, their technology has already received various national and international awards and recognition. We are very pleased to be able to present the products both at the German Rubber Conference in Nuremberg in June 2022 and at K 2022 in Düsseldorf in October,” says Robert Zeppelin, Business Unit Director of the Lehmann & Voss & Co. Luvomaxx business unit.
