ALS2 platinum recovery from spent glass manufacturer conveyors

A glass manufacturer’s conveyor line is more than a belt, rollers and frames. Modern lines also carry drives, gearboxes, encoders, weighing systems, temperature controls, cables, motors and programmable control cabinets. When a line is retired or replaced, that equipment becomes a mixed spent-conveyor stream. The glass bulk material may have little direct platinum value, while a small number of electronic or catalytic components can contain platinum-group metals. The opportunity therefore lies in careful identification and targeted processing, avoiding the assumption that every worn conveyor is a rich ore.

For Australian plants, the stream is shaped by local operating habits. In Melbourne, Adelaide and other industrial areas, managers talk about furnace campaigns, planned shutdowns, changeovers, clean-downs and tonnes processed per shift. A contractor may call the material a decommissioning clean-down, while an e-waste recycler calls it WEEE, or waste electrical and electronic equipment. That variation in everyday language can hide a useful distinction: glass residue, steel, copper and electronic controls need different handling routes.

ALS2Project, associated with Ikoi S.p.A., is developing an acidless separation technology for recovering precious metals from electronic waste and WEEE recycling streams. Its aim is a safer, cleaner alternative to conventional acid-based refining, with potential use in compact precious-metals recovery plants. The approach is relevant where a small, dispersed quantity of platinum-bearing material is mixed with equipment that is too bulky or heterogeneous for a simple bin of scrap.

Using ALS2 for platinum recovery from spent glass manufacturer conveyors should begin with a realistic feedstock assessment. Platinum is usually a trace constituent in this type of stream, so grade, component location and recovery cost matter more than headline metal value. A project can connect a glassworks teardown with a local e-waste processor, an assay laboratory and a precious-metals refiner. That chain turns an old production line into a measured recovery opportunity while keeping the material accountable from the factory floor to the final metal.

Why retired conveyor lines matter

Conveyor replacement often occurs alongside a furnace rebuild, automation upgrade or factory consolidation. Instead of delivering the whole line as mixed scrap, an Australian operator could set aside motors, drive units, sensors, circuit boards, wiring looms, heating elements and control modules before the steel is sold. This modest separation step can reveal which components deserve further inspection and which can follow established metal-recycling channels.

Some legacy equipment may contain platinum-group metals in electronic contacts, catalytic assemblies or specialised components, but presence and quantity cannot be inferred from appearance. A representative sample should be taken across models, service dates and operating conditions. A laboratory assay, component identification and a mass balance are more dependable than a visual estimate or a single handheld reading. Glass, refractory and insulation residues should be characterised separately rather than treated as platinum-bearing material without evidence. The result gives the project a defensible feed specification.

Australian scrap markets are competitive, and buyers price easy-to-handle steel, aluminium and copper quickly. A low-grade electronics stream may travel farther and cost more to sort than its contained metal value justifies. Keeping the assessment close to the source can therefore matter commercially. It also gives the plant a clearer record of what was diverted, what was recovered and what residual material required an approved route.

An acidless route through complex WEEE

Ikoi’s ALS2 concept addresses the separation problem directly. Rather than treating all WEEE as one uniform feed, a recovery plant can use a controlled sequence for selective separation, isolating metal-bearing fractions and concentrating material that may contain platinum-group metals. ALS2Project presents this as an acidless technology intended to reduce dependence on hazardous acid refining and support cleaner, more compact installations. It is a processing platform, not a guarantee that every conveyor component will yield commercial platinum.

For a glass-industry application, the operating sequence would need to fit the physical reality of the site. Equipment would be deconstructed into manageable units, electronic assemblies would be separated from bulk steel and insulation, and representative batches would be tested before production increases. The valuable fraction could then move to an appropriate finishing or refinery process. Each stage requires clear acceptance criteria for feed composition, moisture, contaminants and recovered value.

The acidless label should be understood as a design choice with measurable benefits, not as a claim of zero impact. Water use, energy consumption, maintenance, dust control, noise and the fate of non-metallic residues still need verification. A comparative trial should record chemical handling, operator exposure, waste volumes and recovery yield against an agreed baseline. Those data can show whether the technology is genuinely safer and cleaner in the Australian setting.

Designing a plant for Australian conditions

A compact recovery unit could be sited within an industrial precinct or on a prepared bay near a glass manufacturer, rather than forcing a low-value mixed load onto a long truck journey. That approach is attractive in Australia, where distance between manufacturing hubs, e-waste facilities and precious-metals refiners can erase a narrow margin. The exact location would depend on throughput, land availability, transport routes and the volume generated during shutdowns.

Regulation is another design input. Australia’s National Waste Policy provides a broad direction for improving waste recovery, but implementation and licensing are handled through state and territory systems. A NSW site, Victorian site or South Australian operation may face different environmental and dangerous-goods requirements, so proposed classification and transport should be checked with the relevant EPA and qualified contractors. Secure storage, fire prevention and workplace controls are part of the commercial case.

Local procurement can make the model stronger. Australian glass manufacturers, licensed e-waste recyclers, scrap processors, assay laboratories and refiners would need to share data and accept defined specifications. Procurement teams often ask about tonnes per shift, uptime, assay confidence and chain of custody, while plant operators focus on changeover time and maintenance access. ALS2 would need to answer both sets of questions with local operating evidence.

Measuring value beyond the assay

Platinum’s high value can distort a business case because the recovered mass may be tiny compared with the equipment stream. A serious evaluation should track material processed, the percentage directed to each saleable fraction, the platinum-group-metal grade and the final recovery rate. It should also calculate transport, dismantling, energy, labour and residual-disposal costs. Those figures distinguish a high assay from a profitable recovery operation.

Recovery fits a broader circular economy when non-precious materials remain in useful loops. Steel, aluminium, copper and some electrical components may be refurbished, remanufactured or sent to specialist recyclers, while non-recoverable fractions are characterised before disposal. The best outcome is not simply a larger pile of refined metal; it is a documented chain that reduces waste and avoids sending usable equipment to general scrap. Local reporting can make gains visible to regulators, customers and community partners. It gives sustainability goals a practical measure by linking reuse, waste diversion and recovered metal to recorded quantities.

ALS2Project’s support from the European Union’s Horizon 2020 research and innovation programme adds an important research foundation, but an Australian deployment still needs site-specific validation. During a pilot, operators can test procedures, protective equipment, dust extraction and maintenance routines under real conditions. Clear roles and fatigue controls matter during extended shutdowns. A brief meditation for stress relief can complement, rather than replace, the site’s formal safety plan. A calm handover helps crews notice process changes and record anomalies accurately.

A practical route to deployment

A sensible first move is to select one retired line or a controlled clean-down batch and document every component before disposal. The glass manufacturer can work with an e-waste contractor to remove batteries, lamps, oils and other regulated items, then send representative samples for independent assay. Results should define whether ALS2 is technically suitable, what pre-treatment is needed and whether the recovered fraction meets a refinery’s specification.

If the material passes those checks, a small demonstration can measure throughput, metal concentration, worker exposure, residue volume and the quality of marketable output. A compact unit can then be compared with conventional scrap handling or acid-based refining. The decision should include a sensitivity range for platinum prices, freight and the number of shutdowns each year, since a project that works for one large plant may not suit every Australian operation.

A successful scale-up would also need a clear ownership model. The glassworks can retain responsibility for segregation and traceability, while a licensed partner handles dismantling, processing and final transfer. Refiners can specify assay methods and acceptance thresholds, and regulators can be kept informed through documented waste movements. This division of responsibility protects the material’s value without treating an industrial clean-down as ordinary household e-waste.

Glass manufacturers, e-waste recyclers and precious-metals refiners across Australia can contact Ikoi S.p.A. and the ALS2Project team to arrange a technical discussion, site audit and representative sampling campaign. A conveyor inventory, expected retirement schedule and existing laboratory results would give the project a practical starting point.

With responsible handling and verified recovery performance, spent glass manufacturer conveyors could become a focused source of platinum within a safer, more circular recycling stream.
