A new zero waste hierarchy for the circular economy

Circular economy network Zero Waste Europe (ZWE) has developed a new waste management hierarchy that it says puts the focus on resources instead of waste.
The traditional waste hierarchy is a tool that lists methods of waste management in order of their impact on the environment in a simple diagram. The current waste hierarchy was introduced in the 2008 EU Waste Framework Directive, which sets out the basic definitions of concepts and principles involved in waste management, listing prevention at the top (most preferable) to reuse, recycling, recovery and then disposal at the bottom (least preferable).
However, ZWE is calling for an updated model that would ‘change the mindset from waste management to resource management.’ The organisation states: ‘The driving force of the hierarchy should be not only the safe disposal of our waste but also to ensure that the value of our resources is preserved in the economy for the new generations.’

The new model proposed by ZWE focuses more strongly on keeping resources in use for as long as possible. Therefore, the top two levels focus on ‘products’ not waste, expanding the ‘prevention’ level of the traditional hierarchy out into ‘Refuse, rethink, redesign’. This encapsulates anything that stops waste from being produced, from behaviour change to prevent consumption of single-use items, to rethinking business models to make them waste free by design. This, ZWE says, should be the central priority of economic and environmental EU policies and funding.

The second level, ‘Reduce and reuse’, focuses on keeping used products in use and preventing them from becoming waste, while the third level, ‘Preparation for reuse’, refers to taking waste products and refurbishing them so that they can become usable again. Level four mirrors the traditional hierarchy, with recycling, composting and anaerobic digestion the ideal ‘last option’ for keeping materials in use.

At level five, ZWE prioritises ‘Material and chemical recovery’ over simple energy recovery – this places more of a focus on retaining materials and resources, rather than converting valuable material into energy through, say, incineration.

Finally, at the bottom of ZWE’s hierarchy are disposal options, with residuals management the last option for the waste that is left over after all valuable materials have been reclaimed.
