Top images from around the web for Refuse and rethink
  • The top priority in the waste management hierarchy is to refuse unnecessary products and packaging, and rethink consumption patterns to prevent waste from being generated in the first place
  • This can involve choosing reusable and durable products over single-use disposables (reusable shopping bags, water bottles), avoiding over-packaged goods, and opting for digital solutions instead of physical products (e-tickets, online documents)
  • Refusing and rethinking also involves challenging the linear "take-make-dispose" economic model and designing products and systems for longevity, repairability, and recyclability

Reduce and reuse

  • The next step in the hierarchy is to reduce the amount of waste generated by using products more efficiently and extending their useful life through reuse and repair
  • Reducing waste can involve buying in bulk to minimize packaging, using concentrated products (laundry detergent), and choosing products with minimal or recyclable packaging
  • Reuse strategies include donating or selling used items (clothing, furniture), using refillable containers (beverages, cleaning products), and participating in sharing and rental programs (tool libraries, car-sharing)

Recycle and compost

  • Recycling involves collecting and processing waste materials to create new products, conserving natural resources and reducing the need for virgin raw materials
  • Common recyclable materials include paper, cardboard, glass, metal, and certain plastics (PET, HDPE), which can be collected through curbside programs or drop-off centers
  • Composting is the process of breaking down organic waste (food scraps, yard trimmings) into a nutrient-rich soil amendment, diverting waste from landfills and reducing greenhouse gas emissions
  • Recycling and composting require proper sorting and collection systems, as well as processing infrastructure and end markets for recovered materials

Waste-to-energy vs landfills

  • Waste-to-energy (WTE) involves incinerating waste to generate electricity or heat, reducing the volume of waste sent to landfills and recovering some energy value from residual materials
  • However, WTE is considered a last resort in the zero waste hierarchy due to concerns about air pollution, toxic ash disposal, and the destruction of potentially recyclable materials
  • Landfills are the least preferred option for waste disposal, as they can lead to groundwater contamination, methane emissions, and the permanent loss of resources
  • Zero waste strategies prioritize diverting waste from both WTE facilities and landfills through prevention, reuse, recycling, and composting

Circular economy principles

Closed-loop systems

  • A closed-loop system is one in which materials are continuously cycled back into the production process, minimizing waste and reducing the need for raw material inputs
