Circular engineering
Design for recycling: designing parts and electronics for a real pathway
Recyclability begins in design, but must be demonstrated under the conditions of the chain that will receive the product.
Read article · 7 minPlastics processing
Washing recycled plastics: quality, water balance and effluent management
Washing efficiency is reflected in approved material and control of the streams leaving the process.
Read article · 7 minPlastics processing
PCR extrusion: balancing filtration, degassing and polymer preservation
Pellet stability depends on controlling what enters, what is removed and what changes during processing.

Recycled ABS, HIPS and PP blends: when compatibilisation makes sense
Blending materials to recover value requires knowing the composition and demonstrating the formulation's performance.

Drying recycled polymers: measuring moisture and avoiding clock-based decisions
Completing a set time in the dryer does not demonstrate that the material has reached the condition required for processing.
Read article · 7 minIndustrial waste management
Auditing recyclers: verifying capacity and the downstream treatment chain
A partner assessment needs to connect documents, observed activity and the path taken by materials.
Read article · 7 minIndustrial projects
Implementing recycling lines: from CAPEX to commissioning and acceptance
Buying equipment is one part of the investment. The project's deliverable is an operation capable of producing the specified result.
Read article · 7 minIndustrial performance
OEE, yield and energy: measuring a recycling line without mixing indicators
A line can produce more tonnes while still losing quality, material or energy efficiency.
Read article · 7 minEnvironmental evidence
LCA of recycled resins: comparing alternatives with equivalent functions and boundaries
A useful environmental comparison needs to explain what each alternative delivers and which stages have been accounted for.
Read article · 7 minDownstream treatment chain
Exporting electronic scrap: assessing the pathway under the Basel Convention
An international buyer's appeal needs to be matched by the technical, documentary and regulatory feasibility of the movement.
Read article · 7 minPathways, operations and quality
Pathways, operations and quality
From partner selection to material application.
Tenders, metals, white goods, batteries, inventories, logistics, reuse, testing, pyrolysis and environmental communication.
Contracting and value recovery
Scrap and waste tenders: structuring scope, proposals and selection
A tender starts going wrong when each participant receives a different interpretation of the batch. Procurement work begins with the quality of the scope.
Read article · 6 minElectronic scrap and metals
Circuit boards and metals: from sampling to commercial settlement
A board's value depends on more than the metal present. It depends on how the batch is measured, analysed and paid for under the contract.
Read article · 7 minWhite goods and reverse manufacturing
White goods recycling: refrigerants, foams and fraction traceability
The value of the metal is only part of the decision. Refrigeration equipment requires the identification and control of substances that are not reflected in the sale of the casing.
Read article · 6 minBatteries and risk management
Lithium batteries in electronic scrap: identification, contracting and risk control
A battery may arrive hidden inside an apparently harmless device. Batch management needs to recognise this possibility before movement and processing.
Read article · 7 minOperations and quality
Waste and recovered material inventories: segregation, traceability and quality
A material can lose its market while it remains in stock. Mixing, incomplete identification and a lack of decisions turn a marketable fraction into an operational problem.
Read article · 6 minReverse logistics
Reverse logistics between sites: collection, consolidation and cost by flow
The lowest rate per trip may produce the highest cost per tonne. In operations with multiple sites, quantity, physical volume and waiting time need to be assessed together.
Read article · 6 minReuse and IT assets
Reuse, repair and harvesting: deciding the destination of electronic components
A component removed from equipment may preserve more value than its material fraction. This possibility depends on demonstrated function, demand and preparation cost.
Read article · 6 minMaterial characterisation
FTIR, DSC, TGA and XRF: combining tests for recycled plastics
Different tests observe different aspects of the material. Investigation improves when each result answers a hypothesis and its limitations are explicit.
Read article · 6 minTechnologies and feasibility
Pyrolysis of complex plastics: feasibility criteria and pathway limitations
Producing a liquid in a test does not demonstrate a commercial pathway. Feasibility depends on output quality, qualified buyers and the cost of operating with actual material.
Read article · 6 minCommunication and evidence
Recycled content and environmental claims: building consistent substantiation
Accurate information about a resin can become misleading when presented as a characteristic of the entire product. Substantiation starts with the statement to be published.

Materials and circularity
From material characterisation to proof of results.
Explore decisions on electronic scrap, industrial waste, PCR, separation, data and indicators.
Electronic scrap and IT
Corporate electronic scrap: from inventory to final treatment
Equipment removal begins before collection. A usable inventory and a release rule preserve value and prevent gaps in responsibility.
Read article · 7 minWaste management
Solid and industrial waste management: what to assess before contracting
A well-defined contract brings together the actual characteristics of the waste, the service provider's capacity and proof of service. Price depends on that definition.
Read article · 7 minWEEE plastics and PCR
Plastics from electrical and electronic equipment: from recovered fraction to raw material
A recovered plastic fraction becomes a supply option only when its composition, performance and variability are known.
Read article · 7 minFeasibility and value recovery
Comparing recycling proposals: costs, yield and risks
The proposal with the highest price per kilogram may depend on a yield the batch cannot deliver. The comparison needs to make that condition visible.
Read article · 7 minQuality and characterisation
Sampling waste and plastics: assessing a heterogeneous batch
A precise laboratory result can describe a poorly selected sample. Representativeness starts with defining the batch and the question the analysis must answer.
Read article · 7 minWEEE plastics and PCR
PCR resin quality: batch control and industrial variability
Approval of a sample needs to develop into a supply routine. The challenge is maintaining part performance when the raw material varies.

WEEE plastics separation: validating an industrial pathway
A separation line needs to deliver quality from a variable feed. A machine's performance depends on the material it receives and the next stage.

ITAD and data security: sanitisation, custody and release for reuse
The possibility of reusing equipment needs to be accompanied by a documented decision on its data. Control does not end when the medium leaves the company.
Read article · 7 minIndustrial circularity
Industrial closed-loop systems: from pilot project to recurring supply
Closing a loop requires connecting material generation to demand for a new application. The pilot needs to demonstrate quality, continuity and viable economics.

Recycling and circularity indicators: measuring without distorting results
A rate can be mathematically correct and still communicate the wrong conclusion. An indicator's quality depends on what was counted, when and with what evidence.

Economic decision
Assessing the value of a batch of assets or waste
Price per kilogram alone does not settle the choice between two pathways. The comparison must reach the net proceeds for the same batch.
