From Waste to Wonder Workshops
Vegetable Glycerin
Vegetable glycerin is a byproduct of biodiesel production, resulting from the conversion of vegetable oils. Although often seen as waste, it can be repurposed in bioplastics as a plasticizer, enhancing flexibility, durability, and biodegradability. By using vegetable glycerin, we promote renewable resources and support sustainable manufacturing practices, contributing to eco-friendly product development.
Why?
Glycerin, a byproduct of biodiesel production, was once discarded, raising environmental concerns due to its potential impact on landfills. However, recent trends focus on repurposing this surplus glycerin, transforming waste into valuable resources and enhancing efficiency in resource use.
Where?
Surplus glycerin can be collected from biodiesel manufacturing facilities, refineries, or industry associations. Direct contact with biodiesel producers, exploration of online marketplaces, networking with industry stakeholders, and collaboration with research institutions are avenues to acquire surplus glycerin.
How?
Surplus glycerin often comes with some unwelcome guests, like water, methanol, or leftover salts from the biodiesel production process. To tidy it up, purification methods like distillation or filtration can work wonders, turning this byproduct into pure glycerin. Another option is to source glycerin from companies that prioritize sustainability, using crops that are grown and harvested with eco-friendly practices. Notable producers of vegetable glycerin include AAK Netherlands, Croda, and Koster Keunen, who are all about making glycerin the right way.
