Sourdough subscription services generate: sourdough discard from starter maintenance (compostable or give to customers), flour bag waste, delivery packaging, and production waste.
Sourdough discard is typically the most regular stream, with smaller volumes of flour bags, packaging and general production waste. Discard has culinary value — offer discard recipes to subscribers or partner with animal feed programs.
Use recyclable delivery packaging to align with sustainability-conscious customers. Monthly waste: $100–300.
Key Numbers
- Typical monthly waste: $100–300
- Metro landfill levy (2025–26): $169.79/tonne
- Statewide FOGO rollout: by 2030
- Commingled contamination: about 12%
What You Need to Know
A sourdough subscription is a small-footprint business with a predictable waste profile, which is exactly why it is easy to overpay — a generic general-waste bin priced for a busy cafe is wrong for a micro-bakery. The most regular stream is starter discard, and it should never reach landfill: it composts cleanly, and many bakers redirect it to subscribers or animal feed programmes entirely.
- Sourdough discard — compostable, or offer discard recipes to subscribers
- Flour bags — recyclable when clean and uncontaminated
- Delivery packaging — choose recyclable to match sustainability-minded customers
- Production waste — keep separate from any recyclable streams
Keeping organics out of the general bin matters because every tonne avoided sidesteps the metro $169.79/tonne levy, and Victoria's FOGO (Food Organics Garden Organics) Policy is driving food organics to separate collection statewide by 2030.

How can restaurants reduce food waste?+
Strategies: track waste by type, menu engineering for whole ingredients, portion control, FIFO rotation, specials for near-expiry items, donate surplus to OzHarvest (free, tax deductible), staff meals. Reducing waste 20% saves $500–2,000/month in food costs.
How should a Melbourne meal kit delivery company manage waste?+
Meal kit companies generate: food prep waste at production facility (compostable), ice pack waste (check recyclability), insulated packaging (some are recyclable), damaged ingredients, and general waste. Customer-side packaging waste is a growing concern. Use recyclable or compostable packaging to differentiate. Production facility waste: $500–2,000/month. Offer packaging take-back programs for customer retention and sustainability.
Are compostable packaging items actually composted in Victoria?+
Most compostable packaging requires industrial composting conditions (55 degrees C+) not available at home. In Victoria, compostable packaging CAN go in commercial food organics bins if your composting facility accepts them — check with your provider. Many composters reject it because it resembles plastic.
What waste does a restaurant generate and how should it be managed?+
Melbourne restaurants generate: food waste (40–60%), cardboard (15–25%), glass (10–15%), recycling (5–10%), cooking oil (3–5%), general waste (10–20%). A 100-cover restaurant generates 500–800kg/week. Food waste composting can divert up to 60% from landfill and save $100–300/month.
What waste management do bakeries need?+
Bakeries generate: ingredient packaging (20–30%), food waste (25–35%), cardboard (15–20%), plastic wrap (10–15%), general waste (10–15%). Mid-size bakery: $200–500/month. Food waste composting saves vs landfill. Used cooking oil collection typically free.
