Here comes the preparation on how to make bioplastic from banana peels. We’ve compiled the materials and tips you can rely on as a guide below.

Collection and Storage

For the collection, you must gather banana peels from ripe bananas and store them in an airtight container in the freezer. It helps prevent the decomposition, making them stay fresh.

Thawing and Cleaning

Now, take out the frozen banana peels and thaw them at room temperature. Then, you must clean the peels thoroughly by rinsing them under cold water. We recommend using a brush to ensure the remaining fruit particles and dirt are removed.

Storage Tips

If you want to prepare the banana peels, you can keep them in an airtight container and store them in the fridge. Don’t keep too much as the peels get brown easily due to oxidation. For the stock, you can gather peels from 10 to 15 bananas.

2. Materials and Equipment Needed 

After preparing the banana peels, you have to provide the materials and equipment necessary to make the home-made plastic. To help you out, we have made a list of what you need below.

Banana Peel Powder

It is the main material you’ve previously prepared. You can make the powder from the peels of around 10 to 15 fruits. We recommend making more if you plan to throw DIY projects later on.

Water

Following the previous amount of powder, you will need 2 liters of water to create a solution for blending. Pour the water into a water container or bottle, it’s up to you.

White Vinegar

This material is needed to enhance the breakdown of organic matter. Besides, white vinegar also reduces impurities, like dirt and leftover fruit parts on the peels. You can prepare around one cup. If you don’t have white vinegar, use citric acid.

Blender or Food Processor 

Use either one of them to grind boiled and dried banana peels into a fine powder, enhancing the surface to accelerate biopolymer extraction.

Strainer or Cheesecloth

We personally prefer cheesecloth as you can squeeze the boiled peel better. But, a strainer will also do justice in separating liquid extract from the banana peel powder.

Water Pot

It is used to boil the banana peels which promotes the softening and extracting process of the peel components necessary for making green plastic.

Clean, Dry Surface or Dehydrator

In case you want to accelerate drying, you can use a dehydrator to remove the moisture from boiled banana peels. If not, simply prepare a clean and dry surface for drying.

Airtight Container

This airtight box is crucial to store banana peel powder, preventing moisture absorption that promotes the growth of mold and causes clumping.

Mold or Shape

You can choose what kind of shape or mold you use to form bioplastics. If you want to have plastic bags, you better choose the one with sheet shapes.

Safety Measures

The first thing you need to pay attention to during the process of making the bioplastic formula is to ensure good ventilation. This is especially important during boiling to prevent the inhalation of vapors.

Furthermore, use gloves and goggles when handling hot materials. Be cautious when operating the blender or food processor for blending. The most important thing is to dispose of the waste responsibly by separating it according to its type. Don’t forget to maintain hygiene during the process.

Common Issues

Despite the excellence of these eco-friendly inventions and the benefits they offer for our environment and economy, several common issues occur during the production process. One of the most concerning issues is the consistency of the liquid extract.

The main ingredient, which is agro waste, often poses a challenge in achieving suitable and consistent consistency, thereby affecting the quality of starch-based plastic.

To solve this issue, we recommend cleaning the peels more meticulously and thoroughly to effectively remove all impurities. Thorough washing and cleaning not only address this concern but also promote better extraction, as any residue may hinder the process.

Another challenge is related to the temperature during the heating process. Excessive or insufficient heating can result in suboptimal elasticity of your bioplastic. Consider experimenting with small batches until you achieve the consistency that aligns with your preferences.

Well, the issue doesn’t stop there as natural bioplastics have the tendency to crumble. However, you can address this by monitoring the drying process of the powder. Excessive moisture can impact the quality of the bioplastic’s mechanical properties.

Therefore, we highly encourage you to add a natural plasticizer, such as glycerol, during the blending stage to enhance the resilience and flexibility of banana peel bioplastics.

Applications of Banana Peel Bioplastic

Aside from understanding how to make bioplastic from banana peels, you must also explore their applications. One of the most common uses is crafting bioplastic flower pots.

Despite appearing simple, this project can hone creativity as it serves educational purposes. You can decorate the exterior with various colors and designs according to your taste.
