  • Copper RecyclingCohen

    RECYCLING COPPER CONSERVES ENERGY AND SAVES LANDFILL SPACE. Recycling copper uses about 10% of the energy required to extract new copper. Conserving energy is good news both for our fuel consumption and our CO2 emissions. Mining and extracting new copper is also more expensive than recycling, so recycling helps keep the cost of copper products down.
