Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'отходный продукт'. Use 'отходы производства', 'побочный продукт', or simply 'отходы' depending on context.
- Do not confuse with 'продукт отходов' (product made from waste).
Common Mistakes
- Using 'waste' alone when 'waste product' is more specific for a tangible by-product. Incorrect: 'The factory produces a lot of waste.' (Correct if referring generally) vs. 'CO2 is a waste product.' (Specific).
- Misspelling as 'wasteproduct' (should be two words or hyphenated: waste-product).
