Tasa de valorización

The recovery rate is an essential indicator of the circular economy that measures the proportion of waste subject to recovery processes (material or energy) relative to the total generated. This value reveals the capacity of a system to turn waste into resources, reducing pressure on landfills and the consumption of virgin raw materials.

In operational terms, the recovery rate combines the results of recycling, reuse, composting and energy recovery, offering an integrated view of the environmental performance of the waste management chain.

More than a technical parameter, this indicator acts as a barometer of sustainability, showing how far societies and companies are advancing towards dematerialisation and resource efficiency.

Definition and regulatory framework

Under the Waste Framework Directive 2008/98/EC, recovery is defined as any operation whose principal result is that waste serves a useful purpose by replacing other materials that would otherwise have been used, or by being prepared to fulfil that function.

Law 7/2022 on waste and contaminated soil for a circular economy adapts this principle to the Spanish framework, establishing a clear hierarchy between prevention, preparing for reuse, recycling, other recovery and disposal.

Types of recovery

There are several forms of recovery, classified by the nature of the process:

1. Material recovery

Consists of transforming waste into new secondary raw materials. Examples: recycling of plastics, metals, glass or paper; production of compost or digestate; recovery of aggregates in construction.

2. Energy recovery

Harnesses the energy content of waste through:

• Incineration with energy recovery.
• Gasification or pyrolysis, which convert waste into gas or fuel oil.
• Biogas production in landfills or organic treatment plants.

3. Chemical recovery

Transforms plastic or industrial waste into base raw materials through depolymerisation or chemical cracking, increasingly widespread thanks to technological innovation (see chemical recycling).

Importance in the waste hierarchy

Recovery occupies an intermediate level in the European waste hierarchy: it sits below prevention and recycling, but above disposal or landfilling. Its goal is to recover the maximum possible value, minimising environmental impact and contributing to resource security.

European and national targets

The EU Circular Economy Action Plan (2020) and the European Green Deal promote recovery as a tool to achieve climate neutrality.

Spain, through its State Framework Waste Management Plan, sets targets to:

• Substantially increase the overall recovery of municipal waste by 2035.
• Reduce landfilling to less than 10%.
• Use energy recovery as a controlled alternative to landfill, prioritising material recovery wherever possible.

Recovery rate versus recycling rate

Although both indicators are related, they are not equivalent:

• The recycling rate only measures material recovery.
• The recovery rate also includes energy and biological recovery.

A system with a high recovery rate but a low recycling rate may rely too heavily on incineration, which raises environmental concerns. The ideal balance prioritises material recovery over energy recovery.

Environmental and economic benefits

1. Reduced landfilling: lower generation of leachate and methane emissions.
2. Raw material savings: each tonne recovered replaces virgin materials.
3. Energy security: energy recovery contributes to the production of heat and electricity.
4. Boost to technological innovation: development of biorefineries and advanced conversion plants.
5. Green job creation: treatment, maintenance and environmental control operations.

Quality and traceability criteria

For waste to be counted as recovered, the following must apply:

• The process meets the efficiency criteria set out in EU waste law (for example, the R1 energy efficiency formula in Annex II of the Waste Framework Directive for incineration facilities).
• The material or energy generated is effectively reincorporated into the market.
• Verified, auditable data are recorded, preferably through digital tracking systems (IoT or blockchain).

Extended producer responsibility (EPR) schemes are obliged to report their recovery rates annually to the competent authorities.

Examples of recovery across sectors

Urban sector

Mechanical-biological treatment (MBT) plants combine the separation of recyclable fractions with energy recovery from the non-recyclable reject. Large metropolitan technology parks can recover a very high share of the waste they receive.

Industrial sector

Metallurgical or paper industries use waste as substitutes for raw materials or fuels. In the cement sector, the co-processing of non-recyclable waste helps reduce dependence on petroleum coke.

Agri-food sector

Composting and anaerobic digestion convert organic waste into biofertilisers and biogas, closing the nutrient cycle.

Emerging technologies

• Advanced pyrolysis: breaks plastic waste down into base hydrocarbons.
• Plasma gasification: transforms complex waste into clean gas and vitrified slag.
• Hydrothermal carbonisation: converts biowaste into biochar usable as a carbon sink.
• CO2 capture in energy recovery processes: reduces net emissions and improves plant efficiency.

These innovations consolidate the shift from a waste management model to a circular industrial model.

Limitations and challenges

1. Social acceptance: some technologies, such as incineration, face opposition because of negative perceptions.
2. Investment costs: advanced recovery plants require large initial capital.
3. Regulatory risks: changes in end-of-waste criteria affect market stability.
4. Availability of reliable data: there are still disparities between regions in measuring results.

The key is to integrate recovery into an overall strategy that prioritises reduction and recycling, avoiding the overuse of energy recovery as a final solution.

Complementary indicators

The recovery rate should be interpreted alongside:

• Recycling rate: measures the strictly material part.
• Landfill rate: reflects the residual volume not recovered.
• Material footprint: assesses the total flow of materials consumed.

Analysed together, these indicators make it possible to assess the real circularity of the system and the effectiveness of public policy.

European examples

Several northern European countries recover the vast majority of their waste, combining high material recycling with energy recovery and minimal landfilling; in some cases energy recovery is integrated with district heating. Spain is still in a transition phase, with overall recovery rates that are improving but remain very uneven between regions.

The role of digitalisation

Digital platforms make it possible to measure recovered flows in real time, optimise logistics and improve data transparency. The use of blockchain ensures the traceability of each batch and avoids double counting, while artificial intelligence systems help plan the demand for secondary materials.
