Terracotta manufacturer sustainability should be assessed through defined boundaries, dated data and comparable documents—not the word “green.” A useful supplier review identifies the exact product and factory, checks life-cycle information, examines manufacturing inputs and outputs, and connects those facts to the project’s procurement requirements. Claims without scope, period or evidence remain marketing statements.
Turn “green manufacturer” into answerable questions
Start with the client’s actual objectives. These may include embodied-carbon reporting, responsible raw materials, energy and water management, recycled content, packaging, chemical disclosure, durability, repair, end-of-life planning or a rating-system submission. List each objective with the required metric, unit, document, reporting period and reviewer.
A single label cannot answer all of those questions. Factory practice, product impacts and project outcomes are related but different. A management certificate does not declare product impact; recycled packaging does not establish panel recycled content; long service depends on design, installation, exposure and maintenance as well as the fired-clay unit.
Fix the product, factory, period and boundary
| Identity field | What to request | Why it matters |
|---|---|---|
| Product | Family, profile, body, finish, dimensions, mass and intended use | Generic company data may not represent the proposed panel |
| Production source | Named factory, relevant line and any outsourced processes | Energy mix, equipment, water and waste routes can differ by site |
| Reporting period | Start and end dates, production volume and allocation method | Undated percentages cannot be checked or compared |
| System boundary | Included life-cycle stages, raw materials, manufacturing, transport and end-of-life assumptions | Results with different boundaries should not be ranked as equivalents |
| Verification | Programme operator, verifier, validity and referenced product-category rules | Users need to understand independence, method and current status |
Record the version received and any exclusions. If data represents several factories or an industry average, say so clearly. Ask for a product- and site-specific supplement when the tender requires it, rather than silently treating an average declaration as the exact order.
Use EPD and LCA information within its stated scope
An environmental product declaration reports quantified information under a defined programme; it is not a simple badge that one product is environmentally superior. The newly published ISO 14025:2026 sets principles and requirements for EPD programmes and links their development to the ISO 14040 and ISO 14044 life-cycle assessment framework.
Check declared unit, product description, geography, reference service life if stated, life-cycle modules, scenarios, data quality, allocation, product-category rules, issue and expiry dates, programme operator and verification. Compare products only when scope, method and functional basis allow it. Explain data gaps rather than filling them with assumptions favourable to one bidder.
Interrogate manufacturing data with units and balances
Energy and fuel
Request purchased energy, kiln fuels, onsite generation, renewable claims, units, period and production denominator.
Water
Separate withdrawal, process use, recirculation, discharge and consumption; define the site and measurement route.
Materials and waste
Define pre- and post-consumer inputs, fired and unfired scrap, destination, yield and whether reuse is internal or external.
Air and controls
Request relevant permits, monitored emissions, control equipment, exceedance history and corrective actions where disclosure is required.
Percentages need a numerator and denominator. “Wastewater recycled” may refer to one process stream rather than the entire site; “recycled clay” may mean unfired internal return rather than material diverted from another user. Ask how meters, invoices, weighbridge records and calculations support each figure.
Review health, material and fire statements separately
Request current ingredient or material disclosures, safety data for relevant treatments, glaze or coating information, and emissions evidence where the application or rating system requires it. Avoid translating “natural clay” into universal claims about health, radioactivity, mould, bacteria or toxicity. Each statement needs a defined test, threshold and product scope.
Similarly, a fired-clay material result does not determine the fire performance of insulation, membranes, aluminium supports or the complete wall. Collect the classification and assembly evidence required by the project jurisdiction. Keep environmental reporting and life-safety acceptance in separate review tracks.
Include packaging, transport, service and end-of-life scenarios
Ask for crate and protective-material quantities, recycled content where claimed, treatment declarations, return options and disposal instructions. Model transport with actual factory, port, route, mode, distance and shipment mass when those facts are known. A distant source should not be represented by an assumed local scenario.
For use stage, document inspection, cleaning agents, access, replaceability, expected damage zones and spares. End-of-life claims should identify realistic separation, local facilities and likely destinations for clay and metal parts. Technical recyclability is not the same as an established collection and reuse route on the project site.
Close the 2014 claims with a current supplier evidence pack
The archived page dated 5 September 2014 called LOPO a “green” manufacturer and made absolute claims about maintenance, building-length life, recycling, emissions, health effects, wastewater reuse and regional status. It also stated a recycled-clay percentage without a documented boundary. These are historical self-reports, not current verified facts.
Issue a supplier questionnaire with product identity, factory and reporting period; EPD or LCA documents where required; energy, water, waste and emissions data; material disclosures; certifications; transport and packaging; service assumptions; end-of-life routes; and a signed exceptions schedule. Assign an owner and acceptance date to every requested document. Review current terracotta rainscreen information and the company profile only as starting points for that evidence request.
