E1 · Decomposers solve a waste problem
Food businesses and councils need ways to manage suitable plant and animal waste. Decomposers break down organic material. Industrial systems manage air, moisture and temperature to support the process and check the output. Their accepted materials and controlled conditions may differ from a home heap.
Worked example: A facility finds ordinary plastic fragments in its output. Improve sorting rather than assuming extra time will compost all plastic. Check the facility’s accepted list; do not copy industrial processing of animal waste in a classroom.
Check: Why add ventilation? Answer: Many useful decomposers need air. A scientific explanation identifies how the action helps, not merely that a machine is “better”.
