Are you looking to understand the 5 Rs in a useful and applicable way? Here I explain what they mean (reduce, reuse, recycle, recover and final waste), how they fit into the European waste hierarchy and what to do in your company or municipality to move from words to action.

Why do the 5 Rs matter?

The 5 Rs are an easy way to understand the waste hierarchy, the legal priority in the EU: prevent/reduce → reuse → recycle → recover → dispose. This order minimises impacts and improves resource efficiency. It is included in the Waste Framework Directive and the official EU glossary.

1) Reduce (Prevent)

It means preventing waste from being created in the first place: responsible purchasing, redesigning packaging, extending useful life and optimising processes. It is the highest priority option in the EU and in guidelines such as the EPA Waste Management Hierarchy.

Practical ideas

  • Purchasing based on durability and repairability criteria.
  • Eco-design: less material, reusable formats.
  • Measuring to decide: tonnes avoided per line or campaign.

2) Reuse (and Repair/Prepare for Reuse)

Giving products a second life without turning them into raw materials: returning packaging, reconditioning, repairing and selling second-hand goods. The EU prioritises preparing for reuse over recycling.

Practical ideas

  • Deposit/return systems.
  • Repair shops and spare parts.
  • Reuse shops in municipalities.

3) Recycle

Transforming waste into raw materials: paper/cardboard, plastics, metals, glass, wood, bio-waste (composting). The EU structures its targets by waste streams, and the EPA places recycling above disposal in its hierarchy.

Tip Reverter Industries: conditioning material with industrial shredders and specific lines (e.g., wood) improves output quality and logistics costs.


4) Recovery (valorisation)

When recycling is not feasible, priority is given to recovering energy or materials (e.g. energy recovery from non-recyclable fractions, anaerobic digestion of biowaste for biogas). The official hierarchy places recovery above disposal.


5) Final waste (dispose of)

Last resort: landfill or safe disposal in compliance with environmental conditions. Official plans (such as Pemar 2024-2035 in Spain) limit landfill and promote preparation for reuse and recycling.

How to apply the 5 Rs in your organisation (step by step)

  1. Map of waste by area/shift and LER classification.
  2. 5 Rs Plan: reduction actions (purchasing/eco-design), reuse (return/repair), recycling (segregation, pre-treatment), recovery (biogas/energy), and minimum disposal.
  3. Infrastructure: marked containers, preparation/repair area, pre-treatment equipment (shredding, screening).
  4. Traceability and contracts with authorised waste managers; reporting aligned with hierarchy.
  5. KPIs: % prevention (tonnes avoided), % preparation for reuse, % recycling, % recovery, % to disposal.
  6. Training and container audits (what is mixed, is paid for).

Are the 5 Rs law?

Not as a ‘list’ per se, but they do reflect the mandatory hierarchy (priority of prevention, reuse and recycling) in the EU and similar frameworks.

Is recovery the same as recycling?

No. Recycling returns material to the cycle; recovery usually refers to energy/material when it is not recyclable. The hierarchy places recycling above recovery.

Conclusion

The 5 Rs give you a clear order to follow when making decisions: reduce what you can, reuse what is useful, recycle what can be recovered, recover what cannot be recycled, and leave as little final waste as possible. With metrics, contracts with authorised managers, and good pre-treatment, you can turn the slogan into real results.

In this article, I explain what biomass energy is, where it comes from, how it is converted into heat, electricity or biomethane, and what you need to get started.


What is biomass energy?

Biomass is organic matter of plant or animal origin (forestry and agricultural waste, industrial by-products, sludge, biowaste). Bioenergy is the energy obtained by converting this biomass into solid, liquid or gaseous fuels for heat, electricity or transport.

Why it matters today

In the EU, bioenergy (biomass energy) remains the largest renewable source, accounting for ~59% of renewable consumption in 2021. In 2023, renewables reached 24.5% of total EU energy consumption; biomass plays a key role in heating and cooling. European Commission


Types of biomass and practical examples

  • Solid biomass: forest residues (branches, chips), agricultural residues (straw), wood and by-products (pellets).
  • Biogas/biomethane: anaerobic digestion of agricultural and livestock waste, WWTP sludge and biowaste.
  • Biofuels: used vegetable oils, bioethanol (agricultural waste) for transport.

Tip from Reverter Industries: if you work with wood and pruning waste, start by preparing the material with a good industrial shredder and a wood recycling line to achieve consistent size and quality.


How is biomass converted into energy?

  1. Preparation: crushing/chipping, drying and sorting to obtain a stable fuel (pellets, wood chips, wood shavings).
  2. Thermal conversion: biomass boilers for heat and DHW; electricity is also produced in cogeneration.
  3. Biological conversion: biogas via anaerobic digestion; upgrading allows biomethane to be injected into the grid or used in transport. irena.org

Useful standards: in Spain, the IDAE offers technical guides on thermal biomass and highlights eco-design requirements and UNE-EN 303-5 for solid fuel boilers. idae.es


Benefits (and limitations) of ‘biomass energy’

Advantages

  • Decarbonisation: replaces fossil fuels in heating and thermal processes.
  • Waste management: recycles forestry/agro-industrial waste.
  • Local economy: rural employment and reduced dependence on external sources.

Challenges

  • Resource sustainability (origin, traceability, competition for uses).
  • Emissions and efficiency: suitable boilers and filters; correct design and operation.
  • Logistics: humidity, density and seasonality. (IEA/IRENA detail sustainability and orderly scaling needs). IEA

Regulatory framework and sustainability criteria

  • European Commission – Bioenergy: guidelines and sustainability criteria; biomass remains a renewable pillar. Energy
  • Eurostat: evolution of renewables in the EU (2022–2023) and revised 2030 targets (42.5% with an aspiration of 45%). European Commission
  • Spain: MITECO and IDAE publish definitions, guidelines and participatory processes on biomass and efficiency. idae.es

Conclusion

Biomass energy is a practical way to decarbonise heat and processes, recover waste and generate local impact. The key is to ensure the sustainability of the resource, prepare the fuel properly and comply with regulations. With the right design and reliable technical partners, you can reduce energy costs and your carbon footprint.

Does your brand communicate sustainability and do you want to do it right? In this article, I explain what greenwashing is, why it is a real risk, common examples, and how to avoid it with verifiable standards and best practices.

What is Greenwashing?

Greenwashing occurs when a company communicates exaggerated, vague, or unproven environmental benefits, misleading consumers. The United Nations describes it as tactics that divert attention from real climate action; the EU, the FTC (US), and the CMA (UK) address it with specific rules and guidelines. United Nations – Greenwashing

Environmental pledges: truthful, specific, and verifiable.


Greenwashing vs. responsible communication

  • Greenwashing: generic expressions (‘eco’, ‘planet-friendly’), unverified labels, or ‘carbon neutrality’ without transparent methodology. Regulators consider them misleading if there is no accessible evidence. Green claims code: making environmental claims

  • Communicate well: state specific facts backed up by verifiable evidence (e.g., ‘50% recycled PET, X certification, public technical report’). ISO 14021 regulates environmental self-declared claims: permitted terms, how to justify them and how to verify them. iso.org


Examples of Greenwashing

  1. Empty terms: ‘100% green’, ‘planet-friendly’ without data, methodology or scope (product, packaging, logistics).

  2. Fictitious or unclear labels: leaf or ‘eco’ icons without an accrediting body or public criteria.

  3. Opaque compensation: promising ‘zero emissions’ without detailing calculations, scope limits, and independent verification. ‘Green claims’ directive: Protecting consumers from greenwashing

  4. Significant omissions: highlighting ‘recyclable’ when there is no local infrastructure to recycle it in practice.

‘If you can’t prove it and explain it, it’s not a good claim.’


Regulations and standards you should be aware of

  • EU — Directive (EU) 2024/825 (Empowering Consumers): prohibits unsubstantiated generic environmental claims, unverified labels and misleading comparisons. Member States must implement it by 2026. DIRECTIVE (EU) 2024/825 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

  • EU — Green Claims Initiative: proposal (under development) to require verifiable evidence and common methods when substantiating claims; monitoring and official status. Green claims

  • USA — FTC Green Guides: principles of truthful advertising for terms such as ‘recyclable’, ‘biodegradable’, “compostable” or ‘neutrality’. Federal Trade Commission – Green Guides

  • United Kingdom — CMA Green Claims Code: 6 principles (truthful, clear, no omissions, fair comparisons, life cycle and evidence). Green claims code: making environmental claims

  • ISO 14021: rules for self-declared claims (type II), terms, symbols and verification. iso.org

  • OECD (2025): Overview of misleading claims in the green transition and policy recommendations. OECD


How to avoid greenwashing (practical checklist)

  1. Define the scope: specify whether the claim applies to the product, packaging, operations or brand.

  2. Quantify and test: measurable data (LCA, % recycled, actual CO₂ reduction) and internal/external verification. Federal Trade Commission

  3. Be specific: replace generic terms with figures, dates, standards and coverage (‘from 2024, +32% recycled content (EN ISO XXXX), audited’). Federal Trade Commission

  4. Standards cited: links to ISO 14021, FTC Green Guides, CMA or EU 2024/825 depending on the market.

  5. Make it understandable: create an evidence page with a clear summary and downloadable documents.

  6. Review regularly: claims change if raw materials, processes or legal coverage change. OECD

“Transparency, method and continuous updating.”

Conclusion

Greenwashing undermines trust and exposes companies to legal risks. The solution is well known: solid data, recognised methodologies and transparent communication. If each claim answers the questions of what it promises, how it was measured, who verified it and where it can be seen, you will be in line with regulatory expectations and those of your customers.
