Introduction to Biodegradable Alternatives

As awareness grows regarding the massive plastic pollution issue facing our oceans and landfills, driven largely by single-use plastics, biodegradable alternatives present a promising solution. These materials can breakdown naturally over time without leaving behind persistent microplastics. Replacing conventional plastics with compostable options leads to very positive environmental outcomes.

The Problem of Plastic Pollution

Over 8 million metric tons of plastic waste enters our oceans each year. Scientists estimate there are over 5 trillion pieces of plastic debris floating in ocean surfaces globally.
Plastics can take over 400 years to degrade in landfills, leaching chemicals into soil and groundwater in the process.
Single-use plastics like bags, bottles, straws and food packaging make up over 40% of plastic pollution. Their quick disposal after one use is disastrous for the environment.
Plastic debris entangles and is ingested by marine animals, birds, and fish, leading to injury and death. Over 100,000 marine mammals perish annually due to plastic pollution.
Plastic waste clogs waterways, increasing flood severity and contaminates soil needed for food production. Its effects on environmental and human health are devastating.

The Promise of Biodegradable Alternatives

Biodegradable materials like paper, cardboard, wood, and plant-based plastics break down through natural processes without microplastics remaining.
Most biodegradable alternatives decompose within months through composting, unlike conventional plastics. This prevents persistent pollution issues.
Replacing just 20% of conventional plastics with biodegradable options would prevent 2.7 million metric tons of plastic from entering oceans and landfills per year.
Biodegradable materials help restore soil health, provide nutrients, and reduce spread of contaminants when composted. Their adoption is critical for a circular economy.
Concerted efforts to shift from conventional disposable plastics to biodegradable alternatives can drastically reduce plastic waste and its consequences.

Can plastic be replaced by biodegradable alternatives?

Plastic food packaging and take out containers are a major source of waste that harms natural habitats. However, recent innovations in biodegradable materials provide eco-friendly alternatives that could help divert this waste from landfills and waterways.

For example, in 2022, scientists developed a spray-on, water-soluble coating made from plant-based materials that can replace plastic packaging used to coat produce. After use, the coating simply rinses off with water alone. This type of biodegradable alternative has the potential to dramatically reduce plastic waste from the food industry.
