Are Silicone Ice Cube Trays Better Than Plastic Ones


Have you ever wondered whether ice cube trays made of silicone are more sustainable than those made of plastic? Are using silicone trays more energy efficient than using the ice maker built into your refrigerator?


Ice trays made of silicone are more sustainable than ice trays made of plastic because silicone is more durable and lasts longer than plastic, and the process of making silicone has a lower environmental impact than plastic production. Using silicone ice cube trays instead of your refrigerator’s ice maker is also less energy efficient, though a bit more labor intensive for you.

Why not use plastic trays for ice cubes?

If you’ve ever owned a plastic ice cube tray (and we assume you have), then you already know the problems they bring—the ice is difficult to extract, they tend to crack over time, and refilling them is a chore.


Another factor is the durability of the plastic. Plastics tend to degrade over time, especially when exposed to freezing temperatures. Plastic ice cube trays can become brittle, causing cracks and breakage, shortening their lifespan.


Additionally, certain types of plastic have the potential to absorb odors and tastes, introducing unwanted flavors into the ice cubes and, consequently, into the beverages they cool.


Did you know plastic ice trays are also not a great environmental choice? Plastic materials are known to be harmful to the environment because of the non-organic materials (including BPA, a potentially harmful substance to health), and the energy required because they do not decompose and therefore will not break down if sent to a landfill.


Are silicone ice cube trays safe?

Silicone ice cube trays are generally considered safe to use. Most silicone ice cube trays are made from food-grade silicone and are specifically designed to be safe in contact with food. Food-grade silicone is free of harmful chemicals such as BPA, PVC, and phthalates.


Silicone is generally considered non-toxic and inert, meaning it will not react with food or beverages. It does not release any harmful chemicals or odors into items it comes in contact with, making it a safe material for food-related applications.


To ensure the safety of silicone ice cube trays, it is advisable to follow the manufacturer’s instructions regarding temperature limits and proper usage.


Why do silicone ice cube trays smell?

Silicone ice cube trays sometimes smell for a variety of reasons. Here are some common reasons why silicone ice cube trays may smell:


1. Residual odor during manufacturing
During the manufacturing process, silicone ice cube trays may come into contact with substances or residues that produce a temporary odor. This may include odors from the molding process, release agents, or other materials used in production. If used correctly and cleaned, the odor will dissipate over time.


2. Food residue
If the silicone ice cube tray comes into contact with strongly smelling food or drinks, the silicone may absorb these odors. For example, if the tray is used to freeze fruit with a strong flavor, the silicone may retain some of those smells. Cleaning the tray thoroughly after each use helps prevent this from happening.


3. Dish detergent
Some dishwashing detergents will leave a residue on the surface of the silicone, resulting in an unpleasant smell. If the ice cube tray is cleaned with a cleaner that leaves an odor, the silicone may retain that odor. Rinse the tray thoroughly after cleaning and air dry to help eliminate residual cleaning agents.


To solve odor problems in silicone ice cube trays, consider the following steps. First, wash the tray thoroughly with mild soap and warm water. Fill a tray with a solution of water and baking soda or vinegar, let sit for a while, then rinse thoroughly. Let the tray dry completely after cleaning. Finally, store the tray in a clean, odor-free environment.

Are silicone ice cube trays safe for baby food?

Silicone ice cube trays are generally considered safe for baby food. Silicone is a flexible and durable material that is often used in baby products due to its non-toxic nature, ease of use, and resistance to extreme temperatures.


One of the key advantages of using silicone ice cube trays for baby food is the ease of portion control. Parents can fill each compartment with a specific amount of baby puree, creating individual servings that are convenient for feeding.


Additionally, silicone is generally resistant to odors and stains, reducing the risk of any unwanted flavors or smells transferring to the baby food.


Parents should follow the manufacturer’s guidelines and recommendations for temperature limits and usage to ensure the continued safety and functionality of the silicone ice cube trays in preparing baby food.

Can silicone ice cube trays be used as silicone chocolate molds?

Yes, silicone ice cube trays can be effectively repurposed as silicone chocolate molds. Many silicone ice cube trays are designed with intricate shapes and patterns that can add a decorative touch to homemade chocolates.


The soft and pliable nature of silicone allows for easy removal of the chocolates once they have set, minimizing the risk of breakage or damage during the demolding process.


When using silicone ice cube trays as chocolate molds, it’s essential to ensure that the trays are labeled as food-grade and suitable for use with chocolates.


To use silicone ice cube trays as chocolate molds, simply melt your chocolate, pour it into the mold’s cavities, and allow it to set. Once the chocolate has solidified, gently flex the silicone mold to release the chocolates.
