  • Turning metal wires from pulp bales into profit with TANA Shark

    Metal wires from paper pulp bales are high in value but very hard to shred and clean for selling purposes. Usually the metal wires are stuck with plastics and some remains of the pulping process. This particular type of waste is almost impossible to separate, says a landfill operator in France. Normally the only possibility to handle this type of waste is to dump it at a landfill. This is due ...

  • Managing Compostable Bags At Anaerobic Digestion Plants

    The highest and best use for treating residential food waste is through source separation, sending organics first to anaerobic digestion (to capture energy), followed by aerobic composting (to return nutrients to the soil). Sending food waste to anaerobic digestion (AD) facilities requires appropriate tools and planning for capturing high volumes of material with low contamination. Compostable ...
