What Is Biodegradable, Compostable, Sustainable & Recyclable Packaging?

Sustainability and packaging are still hot topics, thanks to all the attention on single-use plastics and recyclability. Findings from various research sources suggest that about 79% of consumers and 72% of brand owners prefer products that come in sustainable packaging products wrapped in eco-friendly packaging. And get this, two-thirds of consumers are cool with paying more for brands that are engaged in sustainability.

But there’s a problem – these words, biodegradable, compostable, recyclable, and renewable, about sustainable packaging can be confusing as they are overused, interchanged, and misunderstood.

In this article, Opack is here to help you understand the real differences between these terms. When you know better understand the differences between these words, you can make better choices and help things go in a truly eco-friendly direction.

Biodegradable

Biodegradable means that materials can naturally break down and decompose in the environment. A material is considered biodegradable if it can break down through natural biological processes. This breakdown happens through a chemical process where microorganisms break down the materials into natural elements like water, carbon dioxide, and new biomass.

The speed at which biodegradation occurs depends on the specific environment and the material itself. Factors like the right temperature, humidity, and heat can kickstart the biodegradation process.

Many things can be biodegradable, given enough time. The term simply means that a material can break down into natural elements with the help of microorganisms, without specifying how long it takes. Plastics, for example, are known to take decades or even centuries to break down naturally, but they will eventually break down.

Paper, being mainly made from plant material, is biodegradable. Its biodegradation is similar to that of wood in a natural soil environment since wood is a primary component of paper. The rate at which paper breaks down depends on factors like light, water, oxygen, temperature, bacteria, and fungi. Removing lignin, a component in wood that provides structural strength, through pulp bleaching increases the biodegradability of paper.

Compostable

Composting is like a fast and managed way of letting things break down. When we talk about something being compostable, it means the material can break down within about 180 days under specific composting conditions – like high temperature, high humidity, and the presence of tiny organisms and bacteria. Compostable stuff only breaks down in a carefully controlled setup, where things like where the material comes from, how wet it is, how hot it is, and the levels of oxygen and acidity are watched closely.

For things to be compostable, what happens to the material in the end is really important. Compostable stuff is a bit like biodegradable stuff because both are supposed to go back to nature safely. But compostable things take it a step further – they actually give nutrients to the earth once they’re all broken down. The stuff turns into soil that’s full of nutrients, and there’s no leftover, noticeable, or harmful stuff left behind.

What’s the difference between Biodegradable and Compostable?

Briefly, All compostable items are biodegradable, but not all biodegradable items are compostable.

Even though both composting and biodegrading involve breaking down materials into an organic state, the way they decompose is quite different. Compostable materials need a specific environment to break down, while biodegradable materials break down naturally. Generally, composting is a quicker process, but only under the right conditions.

Biodegradation is simply nature doing its thing, breaking materials down into their basic parts. Being biodegradable doesn’t have a time limit. If a company says their product is biodegradable, it means it will break down in a landfill. The crucial factor is how long it takes for the product to break down. Some products break down in months, while others take years. When looking for sustainable packaging, the faster the biodegradation, the better.

Compostable materials go the extra mile by enriching the soil once the product has completely broken down. But this happens only in a suitable composting environment, with high heat, moisture, and the right amount of oxygen. Compostable products might not naturally break down in a landfill; they need specific conditions, often only found in industrial compost facilities. In a landfill, especially one without oxygen, compostable products will take much longer to break down.

Every compostable item is biodegradable, but not all biodegradable items are compostable. For a biodegradable item to be considered compostable, it must break down in a single composting cycle and meet specific standards for toxicity, disintegration, and both physical and chemical effects on the resulting compost.

Sustainable

Sustainable packaging refers to the use of materials and processes in the design, production, and use of packaging that minimize environmental impact and support long-term ecological balance. The goal is to reduce the negative effects of packaging on the environment, considering factors such as resource consumption, waste generation, and pollution.

Sustainable packaging involves using materials that are eco-friendly, such as recycled or biodegradable materials. It also considers the entire life cycle of the packaging, from production to disposal, aiming to minimize energy use and emissions. Additionally, sustainable packaging often focuses on reducing excess materials, encouraging recyclability, and considering the overall environmental footprint.

The aim is to create packaging solutions that meet the present needs of protecting and delivering products while minimizing the impact on the environment and supporting a more sustainable future.

Recyclable

Recyclable refers to materials that can be collected, processed, and reprocessed to make new products. When something is labeled as recyclable, it means it has the potential to be used again rather than being thrown away as waste. These materials –glass, aluminum, plastic water bottles, metal scrap, paper, electronics, textile, wood, wire, cables, plastic products, rubber are often recyclable. The recycling process involves gathering used materials, breaking them down, and then using the recovered materials to manufacture new items. This practice aims to reduce the consumption of new raw materials and minimize the environmental impact associated with the production of goods. Recycling plays a crucial role in sustainable waste management and conservation of resources.

You can find the universal recycling symbol on most plastic bottles, containers, and other packaging products. The symbol looks like a chasing arrows triangle with a number between 1-7 inside.

Renewable

“Renewable” refers to energy sources or resources that are naturally replenished and can be used indefinitely. These sources are sustainable over the long term because they are naturally occurring and can be naturally restored or regenerated. Renewable energy sources include solar power, wind energy, hydropower, and geothermal energy, among others. These resources offer an alternative to finite, non-renewable sources like fossil fuels, as they can be harnessed without depleting the Earth’s resources and contribute to reducing environmental impact and greenhouse gas emissions.

Sum Up

Biodegradable packaging materials naturally break down over time, while compostable ones do so specifically in composting conditions. Sustainable packaging products aim to minimize environmental impact across their life cycle. Recyclable packaging materials can be processed for reuse. Renewable resources naturally replenish, like solar or wind energy. Renewable resources are expected to be engaged in the production of packaging products. Environmentally friendly and eco-friendly describe products or practices with minimal environmental harm, covering aspects like biodegradability, compostability, and recyclability.
