After all, it has thousands of uses from plastic bottles to the modern-day computers and smart phones. What Are Non-Biodegradable Substances? Undoubtedly, biodegradable plastics are much safer than non-biodegradable products in terms of non-pollutant sources. And they are made from renewable materials such as starch (corn, potatoes, cassava, …), sugar (sugarcane, beetroots, …). Some substances are not broken down by the bacteria or saprophytes are called non-biodegradable substances. The non-biodegradable pollutants are the one that cannot be broken down into smaller, harmless and simpler substances. These plastics turn to compost after a certain period and, therefore, cause minimum pollution. The global plastics problem. Although made from natural materials like sugar cane, they are chemically identical to some petroleum-based plastics. Plastics made from fossil fuels generate a lot of greenhouse gas emissions and waste.
