Glass Bottle Cutlery: An Eco-Friendly Alternative to Single-Use Plastics | Nayanama Siriwardhana

The proposed product is a glass cutlery set made from waste glass bottles, designed for households, restaurants, and food service providers as a durable, safe, and reusable alternative to single-use plastic utensils. Waste glass bottles, a prevalent form of solid waste, are 100% recyclable without quality loss, making this project a contributor to circular economic practices.

The manufacturing process involves collecting, sorting, and cleaning waste bottles, crushing them into cullet, melting the cullet in a furnace, molding it into cutlery, annealing to relieve stress, polishing for safety, and rigorous quality control. This process can be scaled using industrial equipment for consistent high-volume output.

This glass cutlery concept is innovative as it is not widely available in the Sri Lankan market. It offers advantages over wooden or metal alternatives (which have higher costs or limited reusability) and addresses health concerns associated with recycled plastic versions. Commercially, it creates a new revenue stream from low-cost raw materials, meeting the growing demand for eco-friendly products and aligning with sustainable government policies for restaurants and catering services.

The project demonstrates how waste glass bottles can be transformed into a commercially viable product with significant environmental, economic, and social benefits.
