Circularity leads to sustainability
A circular economy takes the waste and repurposes it to fit either the same job or a different job. This way, the used materials are put back into circulation. This keeps our environment clean and enhances overall sustainability.
Overall, circularity views waste as a valuable resource which can be on a road of perpetual reuse. As it currently stands, there may not be a greater example of repurposed materials than stone wool products.
One of the things that makes stone wool such a desirable material to work with is the fact that it comes from an unrelenting resource of natural Earth activity. Unlike non-renewable resources, which cannot be re-used, stone wool is made up of rocks that are reproduced via volcanic eruption and earthquake occurrences. Due to this frequency of re-production, there is plenty of opportunity to take advantage of a resource that continues to replenish itself.
Although stone wool products are made from volcanic rock, one of the planet’s most abundant raw materials, ROCKWOOL also practices upcycling on an industrial scale. This is possible thanks to technologies that enable us to use waste from other industries as a raw material. On average, ROCKWOOL stone wool is made from one-third upcycled waste, including slag from the metal industry and sludge from water treatment plants. This means that rather than being sent to landfill, these low-value types of waste are used in producing stone wool insulation that makes buildings more comfortable and energy efficient.
Through products and materials such as these, generations to come will have a cleaner planet to work on and a better chance at becoming less dependent on resources that negatively impact our environment.
