What is Biodegradable Waste?
Biodegradable waste is organic waste that can naturally break down and, under the right conditions, enrich the soil. Environmental factors such as air, water, sunlight, and oxygen, along with living organisms like bacteria and fungi, all play a role in this process.
Examples of waste include leftover food (which presents opportunities for food waste upcycling), kitchen scraps, paper, human waste, manure, sewage sludge, and the remains of deceased animals.
What is Non-Biodegradable Waste?
Non-biodegradable waste such as plastics, glass, and metals does not easily decompose through any natural means. These materials can persist in the environment for thousands of years while posing a threat to our planet and its inhabitants.
Biodegradable vs. Non-Biodegradable Waste: Key Differences
How do biodegradable and non-biodegradable waste really differ?
We break down the key differences below.
1. Examples of Biodegradable and Non-Biodegradable Waste
1.1 Biodegradable Waste
Biodegradable waste materials, as we have previously discussed, break down naturally in the environment due to environmental conditions and the activity of microorganisms.
Examples of biodegradable waste include:
- Plant debris
- Food waste
- Yard waste
- Paper
- Natural fabrics
- Animal waste
- Wood products
Through this decomposition process, waste is transformed into natural elements that can be safely reabsorbed into the environment without causing harm.
1.2 Non-Biodegradable Waste
Non-biodegradable waste, on the other hand, does not decompose easily through biological processes. These materials include:
- Plastics
- Glass
- Metals
- Chemicals
- Electronics
- Other inorganic materials
These non-biodegradable wastes can persist in the environment for long periods of time, contributing to issues such as pollution, habitat damage, and water contamination. If not addressed promptly, these materials can have harmful effects on both humans and animals.
2. Decomposition Time
2.1 Biodegradable Waste
To highlight the distinction between these types of waste further, we must also consider how long it takes different items to decompose. Let’s take a look at some examples:
- Vegetables: Decompose in about 5 days to 1 month.
- Paper: Breaks down in approximately 2 to 5 months.
- Cotton T-shirt: Can fully decompose in about 6 months.
- Leather shoes: Take 25 to 40 years to degrade.
As you can see, there’s a huge variation in decomposition time. This is why it’s important to understand the difference between biodegradable and compostable waste, as we cover below.
2.2 Non-Biodegradable Waste
In stark contrast, some non-biodegradable examples show extremely long or indefinite decomposition times:
- Tin cans: Take around 50 to 100 years to break down.
- Aluminum cans: Decompose in approximately 80 to 100 years.
- Glass bottles: Can persist in the environment for up to 1 million years.
- Plastic bags: Might persist for hundreds of years or perhaps never decompose.
3. Disposal Methods
3.1 Biodegradable Waste
There are multiple disposal methods available for biodegradable waste, including:
- Composting: Composting is the biological decomposition of organic materials by microorganisms. Materials like food scraps, yard waste, and paper products can all be collected and processed through large-scale commercial composting processes, where they are turned into compost, a nutrient-rich fertilizer that supports sustainable agricultural practices.
- Anaerobic digestion: Anaerobic digestion is a natural process in which microorganisms break down organic waste in an oxygen-free environment. Companies that use this method can send their organic waste to anaerobic digestion facilities, which produce biogas, a renewable energy source, and digestate, a nutrient-rich material that can be used as fertilizer.
- Animal feed: Companies are quickly realizing the benefits of turning food waste into animal feed, reducing costs associated with landfill disposal and traditional animal feed. According to the National Library of Medicine, “It is thought that 1 tonne of dry FW could be used instead of the same amount of maize grain to meet an animal’s protein needs.”
3.3 Non-Biodegradable Waste
Disposal methods for non-biodegradable waste include:
- Landfilling: Unfortunately, both biodegradable and non-biodegradable waste are often sent to landfills, contributing to pollution, greenhouse gas emissions, and climate change. The Environmental & Energy Law Program at Harvard Law School states that “Methane emissions from municipal solid waste landfills are estimated to make up over 14% of the United States annual methane emissions.”
- Recycling: Just because a material is non-biodegradable doesn’t mean it has to be landfilled. Recycling is a great solution to keep materials in circulation and improve resource efficiency. For instance, aluminum is infinitely recyclable, with aluminum cans achieving highest collection-for-recycling and recycling rates among beverage containers.
4. Which Is Better?
Biodegradable waste is generally considered better for the environment, especially when paired with proper waste management. Since it naturally decomposes, it helps reduce landfill use and can produce valuable outputs such as compost and biogas, among others.
However, we try to avoid saying that one is always better than the other, as it depends on the type of waste and the management method used.
As we saw above, products like leather shoes are biodegradable but can take up to 40 years to decompose. Alternatively, materials like aluminum will not naturally decompose, but they’re infinitely recyclable, meaning they have the potential to continually support a circular economy.
All things considered, companies must evaluate their specific waste streams and determine which strategies they can implement to reduce environmental impact.
Understanding Composability: Compostable vs Biodegradable
People often use the terms “composability” and “biodegradability” interchangeably, but they have distinct meanings and implications, especially in the context of waste management and environmental impact.
Compostable materials consist of organic substances that break down in a composting environment, producing nutrient-rich compost that enriches the soil and increases cost savings for businesses. In contrast, biodegradable materials refer to any substances that natural processes and microorganisms break down over time.
A common misconception is that if a product is “biodegradable,” it will quickly and harmlessly disappear in any environment. However, “biodegradable” merely indicates that the material will break down at some point, without giving specifics on the time frame or the end products.
Likewise, just because an item is “compostable” doesn’t mean you can simply throw it in your backyard and expect it to become compost. For effective composting, materials need specific conditions, such as the right moisture, oxygen, and temperature levels. These conditions speed up the decomposition process, ensuring the resulting compost benefits plant life.
Biodegradable items decomposition can take anywhere from a few weeks to thousands of years. In contrast, compostable items typically decompose faster, often within a few months if placed in an appropriate composting facility.
In many areas, compostable items must meet specific standards, like breaking down in a commercial composting facility within a set period without leaving harmful residues. Always look for trusted certifications, such as the BPI (Biodegradable Products Institute) label in the U.S. when discerning the difference between compostable and biodegradable products. One of the critical points to remember is the importance of composting for businesses, as detailed by the Environmental Protection Agency.
The Business Imperative for Biodegradable Waste Management
Managing biodegradable waste is a crucial way for businesses to showcase responsibility, earn consumer trust, and achieve regulatory compliance. A growing number of businesses are integrating services like food waste recycling and food by-product waste services into their operations.
As sustainability targets like the United Nations’ Sustainable Development Goals (SDGs) and the United States 2030 Food Loss and Waste Reduction Goal gain traction, people expect businesses to make significant contributions. Actively managing biodegradable waste helps businesses align with these goals, particularly those related to sustainable cities, responsible consumption, and life on land.
Effective waste management is not only a crucial aspect of maintaining regulatory compliance but also a strategic tool for businesses aiming for long-term sustainability and cost efficiency. One study highlighted this critical aspect, as mentioned on ScienceDirect.
Worldwide, regulations on waste management are becoming stricter. If businesses don’t comply, they risk facing legal consequences, including large fines and sanctions. Beyond the immediate financial penalties, non-compliance can also lead to restrictions or even the loss of operating licenses, restricting their market presence.
Identifying and Classifying Biodegradable Waste
To ensure an environmentally friendly footprint, you must accurately identify and classify waste. Here are some tips for precise categorization and its importance:
- Identify organic materials that naturally decompose, such as food scraps, wooden items, and natural cloth. These are examples of biodegradable waste, similar to practices highlighted in butchery waste solutions managing meat sustainably.
- Most items made of plastics (unless labeled as biodegradable or compostable), metals, and glass are non-biodegradable. Always check labels and product descriptions to verify.
- Recognize recyclable products by the symbols they display.
- In both household and business environments, education is vital. Consistently train your staff members on proper categorization guidelines.
By classifying waste correctly, you ensure that each waste type undergoes the best processing method, whether it’s composting, recycling, or landfill disposal. This approach minimizes environmental damage and supports a circular economy.
On the other hand, improper disposal might result in legal consequences, particularly for businesses. Correct categorization guarantees you adhere to local waste management regulations, reducing the risk of fines or sanctions. here to local waste management regulations, reducing the risk of fines or sanctions.
