Chilean Grape Group is increasingly aware of the importance of dedicating time and investment to innovation. Going one step further is nowadays an essential issue to solve environmental problems, but it is also an important value at social and commercial levels.
That is why today we have established a strategic alliance with Biofiltro, a company that offers us a patented solution to transform wastewater and agro-industrial waste into an important asset in these three fundamental pillars of the winery’s activities. The purpose of this alliance is to ensure the quality of the effluents, to treat the ILW (Liquid Industrial Waste) sustainably, in order to generate savings on issues related to energy consumption, the use of chemicals, and the removal of sludge.
At our facilities located in Isla de Maipo, we now pre-treat our waste, which allows us to safely comply with the environmental requirements regarding the water that is returned to the river. We manage to filter them of their pollutants up to 99%, even those generated during harvest. For this, we use a natural system called BIDA (Biofiltro Dinámico Aeróbico – Biodynamic Aerobic Biofilter), which works through the digestive process of worms that carry out this work in only four hours.
As a result, we obtain high-quality water, which we return to the river, but which can also be used immediately for agricultural irrigation. And as a by-product of the aforementioned process, humus is generated, a natural, nutritious, and valuable fertilizer for the soil. This sludge is delivered to independent companies that turn it into compost, which is then used to improve crop yields and soil health.
Studies carried out concerning GHG emissions (Greenhouse Gases), show that these are reduced by 91% compared to other water treatments, with the positive addition that worms perform this work sustainably.
Chilean Grape Group has been working with Biofiltro since December 2020. The use of this technology is an important support in obtaining certifications such as the sustainability code on waste management. But above all, it is important to emphasize that water consumption during the harvest is strongly reduced due to the control systems implemented in the facilities, and, in addition, it gives us greater flexibility in the water treatment process.
