Single-Stream vs Commingled Recycling: Which Delivers Better Results? — a common question for Melbourne businesses managing their waste costs. Commingled recycling suits small businesses with limited space and low waste volumes. Businesses generating significant cardboard, metal, or glass should source-separate these streams for cost savings and higher recycling rates. Victoria's four-stream system is driving towards more separation, not less.
