“All projects have a positive impact, reducing carbon dioxide emissions, generating biodiversity and developing rural workers”.“The company develops plastic products through virtuous industrial processes leaning towards 0% Scrap, recovering their post-industrial waste and converting them into new products”.“We also [have a positive] impact [on] the environment through our 3R processes and through a sustainable and collaborative value chain”.“We aim at reducing the use of nonrenewable energy throughout the wine production process, reaching 85% solar energy use (…) Lastly, we aim at reusing treated wastewater”.“GEA helps and encourages organizations to adequately and responsibly manage their recyclable waste, thus preventing tons of valuable materials from being sent to a landfill and reintegrating them into society”.“Our material, recycled leather, gives a second life to discards linked to the value chain of the leather industry”.“Vivero San Nicolas S.A preserves the resources used and reduces the consumption of hazardous substances and raw materials by reusing waste and input materials”.
“CARNE focuses not only on respecting sustainable agricultural production but also on working with local communities to strengthen local agricultural development”.“We participate in the radical change that is needed, helping cities to increase their bio-capacity to sustain life (regeneration), to improve the circularity of resources (circular economy) and to facilitate training and development of local capacities (land development)”.“Limpiolux includes people who face repeated work barriers, focusing its efforts on providing quality work and promoting personal and professional development of persons so that they can enhance their employability and improve their quality of life”.“Generating 1000 opportunities of decent work for the local population (…) by trading organic yerba mate grown by smallholder and family farmers and indigenous communities under the shade of native tree species (…) while empowering local communities by working with them under fair trade standards”.“Regarding social problems, we work with Inclusion as a premise; Grupo Advance employs persons with different barriers, such as former prisoners, people with disabilities, and transgender people, among others”.“(…) Santex decided to solve both problems: ensuring that women account for 50% of management positions, adjusting wages to promote equality and, simultaneously, creating a Nursery”.
