Non-biodegradable substances are materials that cannot be broken down into simpler substances by biological processes or decomposers.
Example: Plastic,glass,or metal cans.

$1$. Segregation of waste at the source by using separate dustbins for biodegradable and non-biodegradable waste.
$2$. Adopting the $3R$ principle (Reduce,Reuse,and Recycle) by reusing items like plastic containers and recycling materials like glass and metal.
