Exploring Glass Circularity - Sean and Rui Xiang from SodaLemonSG.com
As university students, sometimes it may be inevitable to question the utility of the knowledge that is kept within the confines of the theoretical boundaries of school.
During a trip to Canada, Sean witnessed first-hand how discarded glass could be given a new lease of life and be upcycled into artisanal goods.
It was after in-which he decided, with his co-founder, that they should get their hands dirty and apply what they've learned to help make glass more sustainable in Singapore.
What is Soda Lemon SG?
The name "Soda Lemon" was inspired from the type of glass they work with, known as "soda-lime glass". Soda-lime glass is commonly used for glass containers to store food and drinks. Soda Lemon SG was born from their founders' belief that while profit is necessary for a business, its main foundations should be rooted on the pillars of sustainability.
Their business model strives to balance between the economy, society and the environment we live in. They aim to transform the way our society views glass both as a resource and as a material.
They believe that we can do our part to reduce our society's impact on nature -- one quality product at a time.

Soda Lemon's Beginnings
Hear about Sean's trip to Yellowknife that gave him an opportunity to witness first-hand how to upcycle glass like what the engineering of Yellowknife did for the many wine bottles in the small town.
This was an opportunity for them to go beyond what was learned in university and 'get their hands dirty'.
Back to School for technical learning
Going back to school after finishing a degree? That is what Sean did as he embarked on the Institute of Technical Education route to understand the ins and outs for mechanical engineering. Click play to find out what he has learned and how it has helped him navigate technical decisions for Soda Lemon SG on a whole new level.
Soda Lemon's Emphasis on Sustainable Packaging: Everything has a cost
Everything has a cost, especially packaging that can easily take up 60% of the cost. There is a cost to everything and even more so from taking the route of delivering a cheap price. Click play to find out the creative ways that Soda Lemon SG has embraced to be economical and sustainable.
