Sustainability
Products conceived for recovery from the start: monomaterials, separable joints and a recyclable construction. Recyclability is decided in development – not at the sorting plant.
At a glance
Design for recycling describes the recyclable design of plastic products: a product is constructed so that, at end of life, it can be collected single-material and recovered as a material. The central levers are monomaterials instead of composites, detachable instead of bonded joints, avoiding disruptive coatings, and clear material marking per ISO 11469. Semadeni already accounts for these criteria in product development and orients itself on recognised design guidelines such as the RecyClass criteria. Because function, regulatory requirements and recyclability occasionally conflict, we weigh them per product and application – rather than claiming recyclability across the board.
Two routes to recyclability
Development & engineering
We check early which material, which joining technique and which marking your part can carry – mono-material instead of composite, detachable instead of bonded joints, marking per ISO 11469.
Evidence & compliance
The PPWR requires recyclable packaging from 2030. We document material and marking; assessing recyclability itself remains product-specific and is not given as a blanket assurance.

Our approach
Later recoverability is largely set already in construction. We therefore start early: monomaterials instead of composites, mechanical joints instead of bonding, and a material marking that eases sorting and reprocessing.
Construction principles
One material instead of a composite – a PP container with a PP lid rather than a material mix. Single-material purity is the basis for high-grade recycling.
Detachable instead of bonded joints, so components can be separated at end of life without tools or with simple tools.
Material marking per ISO 11469 eases sorting and reprocessing in the recycling chain. Expected to apply until August 2028 – the PPWR marking then takes over.
No incompatible label adhesives, coatings or dark pigments that impair sorting and recyclate quality.
In practice
Recyclable design is always a trade-off: some functions or regulatory requirements call for materials or joints that run counter to pure recyclability. We make the trade-off transparent and decide per product.
What we implement
What remains a trade-off
Design for recycling means shaping a plastic product from the construction stage so that, at end of life, it can be collected single-material and recovered as a material. The focus is on monomaterials, separable joints, recycling-compatible colours and clear material marking.
Four levers matter: a single material where possible (monomaterial) instead of a composite, detachable rather than bonded joints for disassembly, avoiding disruptive coatings and label adhesives, and material marking per ISO 11469. Which solution fits depends on function and application.
Single-material plastics are markedly easier to separate after collection and to reprocess into high-grade recyclate. Material composites – different plastics, or plastic-metal combinations – must be separated at high effort and more often end up in thermal recovery. We therefore prefer PP-on-PP or PE-on-PE.
Yes. We bring recyclability into development from the start – from material choice through joining technology to marking. Recognised design guidelines such as the RecyClass criteria serve as orientation. The concrete trade-off between function, standard and recyclability is resolved per product.
Request adviceBoth belong to the loop but are not the same: design for recycling ensures a product is well recoverable at the end; recyclate use employs already reprocessed material in the new product. Ideally the two interlock – wherever standard and application allow it.

The RecyPac association was founded in Zurich on November 30, 2023. Stakeholders along the entire value chain have joined forces to establish a national, harmonized system for the collection and recycling of plastic packaging and beverage cartons in Switzerland. Not all environmental organizations support recycling. How useful is plastic recycling really?
Sales, grouped or transport packaging? The PPWR, applicable from 12.8.2026, requires correct classification. What counts as packaging and what companies need to check.
The EU Packaging Regulation (EU) 2025/40 applies from 12 August 2026. Obligations, deadlines, current status and what the Packaging Regulation 2026 means for Swiss manufacturers – explained concisely.
We bring recyclability into the construction from the start – material choice, joining technology and marking, weighed per product.
The goal is a publishable base without wrong information – not completeness. Anything missing or that could go deeper: report it as "idea for later". We will keep expanding after go-live.
You go through your pages and report what is factually wrong. Expect three to five minutes per page.
Please report: Anything missing, outdated or wrong – and anything visibly broken.
Please don't report: Taste, wording polish, wishes. And that forms do not arrive: that is intentional.
