Glass

Glass is made from naturally abundant silica, soda ash, and lime. It is completely inert, meaning it won't leach chemicals into food or drinks. Borosilicate glass adds thermal shock resistance, making it ideal for kitchenware. Recycled glass is used in up to 90% of new glass containers.

Sustainability benefits

• 100% recyclable and can be recycled endlessly without losing properties
• Inert and non-leaching — safe for all food and drink contact
• Made from naturally occurring, plentiful raw materials
• Borosilicate variant is thermal shock resistant and extremely durable

Drawbacks to consider

• Heavy and fragile compared to alternatives
• Energy-intensive manufacturing process
• Only ~31% recycling rate in the US despite being fully recyclable
