Silicone & Plastic

Silicone

Recyclable, but complex.

While less common, silicone can be repurposed via energy-intensive processes.

• Typically downcycled; not used for new food-grade products.
• Repurposed into industrial materials like sealants, adhesives, and coatings.
• Methods include physical breaking and chemical processes like catalytic cracking.

Plastic

Recycling faces major hurdles.

Seems simple, but is complicated by material diversity and contamination.

• Difficult Sorting: Many types (PET, HDPE, PVC, etc.) must be separated, which is costly.
• Contamination Issues: Additives, colorants, and food residue reduce the quality of recycled material.

Silicone

Environmentally inert.

While it doesn't biodegrade, it also doesn't release harmful substances. The common type, Polydimethylsiloxane (PDMS), remains stable and non-toxic in the environment.

Plastic

Creates harmful microplastics.

Persists for hundreds of years, breaking down into tiny toxic particles (like from Polyethylene, PE) that pollute ecosystems and enter the food chain.

Silicone

The safer, durable choice.

• Food Safe: Generally FDA-approved, though specific testing for high-fat foods isn't always detailed.
• Ideal for Reusables: High durability makes it perfect for items like milkshake straws or bakeware.

Plastic

Creates harmful microplastics.

• Food Safety: Varies by type; some plastics are unsuitable for hot or high-fat foods.
• Best Application: Suited for scenarios where rigidity and low cost for mass production are key.
