Zero Waste Solutions

The Zero Waste Principle There is often confusion about what Zero Waste means. It may seem a concept that is unachievable. All processes produce waste, no process is 100% efficient. However, we can plan for the elimination of waste. =>The Zero Waste goals: Maximise recycling Minimise waste Reduce Consumption Ensure products are re-used and recycled

Benefits Of Recycling Cost avoidance from landfill charges. Commercial value of selling to different industries. Environmental compliance value – Move towards Zero Waste. Increase land utilisation. Allow customers to focus on their Core Business of Making Finished Products. Utilisation of all by products to produce a commercially viable product that returns benefits. Environmental Quality Commercial

Objectives Find Technical & Economical Solution’s for Customer By Products. Current arisings from normal production. Existing stockpiles Maximise the value in use for Customer Optimise usage of high value by products Consume by products to prevent landfill Provide lower cost raw material substitutes External sales revenue Provide a future proof solution Environmentally sustainable
