Some materials that contain polypropylene are not biodegradable because the proper enzymes are missing from the environment. However, there are plenty biodegradable materials with this same component.
None are both, but all are some?
Older milk cartons were not made of biodegradable materials. The newest milk cartons that are produced are made of biodegradable materials.
Biological action of microorganisms causes degradation of biodegradable materials.
Non-biodegradable materials do not break down easily in the environment like biodegradable materials do. It can take hundreds or even thousands of years for non-biodegradable materials to decompose, leading to long-lasting pollution and harm to the ecosystem. Recycling and proper disposal of non-biodegradable materials are crucial to mitigate their negative impact on the environment.
Some are, some aren't. It just has to do with what they are made out of. Not all materials can biodegrade, just because of their chemical composition.
Many non-biodegradable materials can be converted into energy by burning them. Most plastics will burn. Bear in mind however that many of them produce toxic fumes when burned. Some non-biodegradable materials have no good way to convert them into energy. Used tin cans are not biodegradable and don't burn. They are possible to recycle however.

Biodegradable materials are substances can be consumed by microorganisms (can be decomposed). Food waste, paper, linens, and wood are all examples. On the other hand, most things like metal, ceramics, and plastic are not readily biodegradable.
Biodegradable packing materials include: * popcorn * straw * wood excelsior * Shredded paper
Many food scraps like orange peels and banana peels are biodegradable. Also wood leaves, grass clippings, straw, corn, plants, animals, cotton, wool, and other earthen materials are biodegradable. Generally plastic, building materials, and other manmade substances are not biodegradable.
Tinsel is typically made from plastic materials, such as PVC or Mylar, which are not biodegradable. Instead, these materials can persist in the environment for many years, contributing to plastic waste. Some eco-friendly alternatives made from biodegradable materials do exist, but traditional tinsel should be disposed of responsibly to minimize environmental impact.
