The short answer
Biodegradable waste can be broken down by living processes under the right conditions. Non-biodegradable waste does not readily break down that way.

18:48A word is not a waste route.
Kitchen examples
Food waste, garden cuttings and paper can be biodegradable in suitable systems. Mixed plastics, metals and glass are different materials with different routes.
18:56But biodegradable does not automatically mean suitable for your home compost, your council food-waste collection or recycling route.
19:03Why compostable is stricter
Compostable products should say what composting setting they are designed for. That is more useful than vague biodegradable wording.
