Pottery studios generate: clay waste and trimmings (can be reclaimed and reused), glaze waste (may contain heavy metals — check hazardous classification), broken bisque and glazed pieces (general waste — not recyclable), and kiln furniture at end-of-life.
Clay reclamation reduces waste to near-zero for clay streams. Glaze chemicals containing lead, cadmium, or barium are hazardous.
Monthly waste: $50–150.
Key Numbers
- Monthly waste cost: $50–150
- Clay reclamation: Near-zero clay waste
- Hazardous glaze metals: Lead, cadmium, barium
- EPA max corporate fine (GED breach): ~$2.03 million
What You Need to Know
A pottery studio splits cleanly into a near-zero stream and a stream that needs care. The trap is treating glaze waste like ordinary rubbish — some of it is genuinely hazardous:
- Clay waste and trimmings — reclaim and reuse; this brings the clay stream to near-zero.
- Glaze waste — may contain heavy metals; glaze chemicals with lead, cadmium, or barium are hazardous and must not go to general waste.
- Broken bisque and glazed pieces — general waste, not recyclable.
- Kiln furniture — dispose at end-of-life.
Mishandling heavy-metal glaze is precisely the risk the Environment Protection (Management of Prescribed Waste) Regulations 2021 exists to control, with EPA corporate fines for serious breaches reaching about $2.03 million.

What waste do printing companies produce?+
Print businesses generate: paper offcuts (30–40%), ink waste (5–10%, often hazardous), solvents (hazardous), plastic substrates (10–20%), metal offcuts (5–10%). Ink and solvents are PIW requiring EPA tracking. Monthly cost: $300–1,000.
How should a jewellery workshop manage waste?+
Jewellery workshops generate: precious metal filings and dust (valuable — recover and sell), chemical waste from cleaning solutions and acids (hazardous), polishing compounds, packaging, and general waste. Precious metal recovery can offset costs. Chemical waste requires licensed disposal. Monthly waste: $100–300.
What waste does a furniture manufacturer produce?+
Furniture manufacturers generate: timber offcuts (30–40%), upholstery waste (15–25%), adhesive and finishing chemicals (potentially hazardous), metal hardware waste, packaging, and sawdust. Clean timber offcuts can be recycled at $80–120/tonne. Sawdust extraction systems reduce airborne waste. Monthly cost: $500–2,000.
What waste does a commercial printer or sign shop generate?+
Commercial printers generate: paper/substrate offcuts (30–40%), ink waste (PIW — requires EPA tracking), chemical cleaning solutions (PIW), aluminium printing plates (recyclable at $0.50–2/kg), and packaging waste. UV-cure and solvent-based inks are hazardous. Monthly waste cost: $300–1,200. Paper offcuts should be recycled — baling earns rebates of $50–100/tonne.
How should a timber yard manage waste?+
Timber yards generate: sawdust and wood chips (30–40%), offcuts and damaged timber (20–30%), packaging (10–15%), treated timber waste (CCA — hazardous), and general waste. Clean sawdust and chips have value as landscaping mulch or biomass fuel ($0–30/tonne). Treated timber waste costs $150–250/tonne at licensed facilities. Monthly waste: $500–2,000. Sawdust extraction reduces dust hazards.
