## Understanding Biodegradable Poly Bags.
Biodegradable poly bags are a sustainable alternative to traditional polyethylene plastic bags. They're designed to break down more quickly under certain conditions, reducing long-term waste in the environment. If you're looking to adopt greener practices for your business or personal use, here are some essential tips to choose the right biodegradable poly bags.
### Know the Types of Biodegradable Bags.
Familiarize yourself with the different types of biodegradable bags available in the market. The most common types include:
1. **Starch-Based Biodegradable Plastics**: Made from natural starch, these bags decompose relatively quickly but might not be as strong as traditional plastic bags.
2. **PLA (Polylactic Acid) Bags**: Derived from corn starch or sugarcane, these are typically used for food packaging and compostable yard waste bags.
3. **PHA (Polyhydroxyalkanoates) Bags**: Produced by bacterial fermentation of sugars, PHA bags are biodegradable and compostable but are often more expensive.
4. **Oxo-Biodegradable Bags**: These contain additives that aid the degradation process when exposed to oxygen and UV light. However, they might leave behind microplastics.
Understanding these types will help you decide which suits your specific needs the best.
### Evaluate the Environmental Impact.
When choosing biodegradable poly bags, consider their entire lifecycle, from production to disposal. Here's how to evaluate their environmental impact:
1. **Production**: Assess the raw materials used. Bags made from renewable resources like corn or sugarcane are generally better than those made from non-renewable resources.
2. **Decomposition Rate**: Determine how quickly the bags break down under normal environmental conditions. Some biodegradable bags require industrial composting facilities to decompose properly.
3. **Residue**: Ensure that the bags leave no harmful residues or microplastics after decomposing, as these can contribute to pollution.
Evaluating these factors will help you choose bags that truly benefit the environment.
### Check Certification and Standards.
Certifications are crucial in verifying the claims made by manufacturers about their biodegradable products. Look for the following certifications:
1. **ASTM D6400**: Indicates the product is certified for compostability in industrial composting facilities.
2. **EN 13432**: European standard for compostable and biodegradable products.
3. **OK Compost**: Certifies the product can be composted in backyard composting systems.
4. **BPI Certification**: Issued by the Biodegradable Products Institute, indicating the product meets stringent standards for compostability.
These certifications will help you avoid greenwashing and ensure you're purchasing genuine biodegradable bags.
### Consider the Cost and Practicality.
Finally, think about the cost and practical use of biodegradable poly bags:
1. **Cost**: Biodegradable bags are typically more expensive than conventional plastic bags. Evaluate your budget and determine the feasibility of switching to biodegradable options.
2. **Usability**: Check the strength and durability of the bags. Some biodegradable bags might be less durable compared to traditional polyethylene bags.
3. **Availability**: Make sure biodegradable bags are readily available in the quantities you need.
Balancing cost with environmental benefits is crucial for making a practical and impactful switch.
## Conclusion.
Choosing the right biodegradable poly bags involves understanding different types, evaluating their environmental impact, checking for credible certifications, and considering cost and practicality. By following these tips, you can make an informed decision that supports sustainable practices while meeting your requirements. Transitioning to biodegradable bags is a positive step towards reducing plastic waste and promoting a healthier environment.
