Cradle to Cradle at Mosa
In the Cradle to Cradle programme, products are assessed based on five criteria: purity of raw materials, recycling, energy and water usage, and social conditions.
The basis of Cradle to Cradle is the use of pure raw materials that do not harm the environment or human health. The main components of tiles are clay and sand – natural ingredients that are abundantly present in nature. The composition of our tiles is analysed down to the ppm level (parts per million). Mosa tiles contain no toxic substances, such as lead, mercury or cadmium. And no toxic substances are emitted either during or after their long lifespan, making our tiles 'VOC free'.
Is the product suitable for (unlimited) reuse? Are products actually recycled? These are the things that Cradle to Cradle looks for. By using pure raw materials we can say yes to the first question. Mosa strives to achieve the second by reusing production waste, processing secondary materials and collecting cutting waste from tiles at the larger projects in the Netherlands. The wall tiles contain 22 or 25 percent pre-consumer recycled content and the floor tiles contain 21 or 45 percent, making Mosa tiles suitable for reuse in a circular production cycle.
Cradle to Cradle views water as a scarce and precious resource, which must be handled properly. Reuse is essential to this. Mosa’s goal is to ensure that all water used in the production process is reused or evaporated by 2020. More steps are being taken every year to achieve this goal. The production cycles are now closed-loop and all the water for both our factories is purified on site, which means we require 60 percent less water than before.
Cradle to Cradle is not just about the amount of energy used, it is also about the source of that energy – because renewable energy sources are limitless. Green energy now covers a third of our energy needs. We continue to expand this and we are currently searching for an alternative source for the natural gas used to heat the kilns. Until this source becomes available, we will focus on energy-saving projects and the reuse of residual heat. This has enabled us to reduce CO² emissions by 48 percent over the last ten years; fine particulate emissions have dropped by 91 percent to almost zero.
Cradle to Cradle requires the manufacturer and its suppliers to operate under good working conditions. Mosa consciously opts to continue its sustainable production in Western Europe, where it is close to important consumer markets and can use materials from the area: almost 90 percent of our raw materials come from monitored quarries in the region. By making a product locally that fits with both contemporary and future architecture, Mosa is remaining loyal to its birthplace: Maastricht.
