A simple garage SOP
Drain into a funnel over a closed drum. Log approximate litres per day. Keep the drum on a tray. When the drum is three-quarters full, list or trigger pickup on BioTradX.
This takes minutes. It prevents the most common inspection issue: oil-stained floors and unnamed buyers.
How much oil a garage generates
A busy multi-brand workshop doing 15 to 30 oil changes a day can generate 40 to 80 litres daily, depending on vehicle mix. That is enough for weekly pickup in most cities.
Talking to staff
Make one person responsible for the drum. Ban mixing of kerosene, coolant, or brake fluid into the oil drum. Contamination is how a good lot becomes a rejected lot.
Collection through BioTradX
Create a garage seller profile, list used engine oil, and accept a recycler who shows authorisation. Repeat weekly or fortnightly.
