The waste management hierarchy presents a systematic order of managing waste according to what’s best for the environment. Prevent – Top priority is placed on reducing or preventing waste. Can waste be avoided? Reduce – Can less materials be used in the design and manufacturing stage? Reuse – Can materials be reused in other areas of your production process, or by others? Repair – can the materials be repaired? Recycle – Can the materials be recycled, either in whole or in part to turn into a new product Recover – Where further recycling is not practical or possible, energy or materials could be recovered from waste through processes such as anaerobic digestion or incineration.

The waste management hierarchy builds on the "Three Rs" (reduce, reuse, recycle) by expanding into a five-step process that ranks actions from most to least preferred. This approach aligns with life cycle thinking.

Reduce - The top priority is to prevent waste before it’s created. This involves using fewer raw materials, avoiding unnecessary packaging, and focusing on resource-efficient production.

After reduction, reusing products and materials is the next best option. This extends the life of items, delaying them from becoming waste.

Repairing broken or damaged items allows them to stay in use longer, reducing the need for replacements.

Recycling involves breaking down waste materials into new products. Though beneficial, it requires energy and resources to process materials.

When items can no longer be recycled, energy or materials can be recovered from waste. This includes processes like incineration (with energy recovery), anaerobic digestion (breaking down organic waste to produce biogas), or gasification.

The final and least desirable option is to send waste to landfills or incinerators without energy recovery. Disposal methods, particularly landfilling, can have long-term environmental consequences.
