Green Producer Diary

My Motivation

I wanted to design a bag that people would keep for years, not seasons. I noticed most bags fail not because of style but because they are difficult to repair or made from layered synthetic materials. Sustainability matters to me because design decisions made on paper determine environmental impact long before production begins. If we design durability and repairability from the start, waste almost disappears. My goal was to prove that elegance and responsibility can coexist.

My Vetrine Journey 

In the first month I researched why handbags are discarded and found that mixed materials prevent recycling. During months two and three I experimented with fewer components and developed a structure that could stand without plastic reinforcement. Around month four I struggled to find leather that was both traceable and chrome-free, so I contacted smaller tanneries instead of large suppliers. By month five I redesigned the lining to be removable, which solved both cleaning and recycling issues.
The biggest challenge was balancing durability with disassembly — strong stitching usually means permanent construction. I solved this by combining reinforced seams with accessible repair points instead of glue. During month six I prototyped handles that could be replaced without damaging the body. Month seven focused on testing: abrasion, weight, and daily use simulations. In the final month I simplified the hardware to reduce material types and documented every step for transparency.

Sustainability in Action

How did you consider and implement the following aspects in your product development?

 

Sustainability Aspect

My Actions

Environmental

Used chrome-free leather, removable recycled lining, minimized glue, reduced material types to improve recyclability

Social

Collaborated with small European workshops, ensured traceable suppliers, maintained direct communication with makers

Financial

[Designed for long lifespan and repairability, modular parts reduce replacement cost, efficient cutting patterns reduced material waste

 

A Message to Consumers

This bag is not sustainable because of a single material — it is sustainable because every decision was made to extend its life. You can repair it, clean it, and eventually separate its parts. When you choose it, you support a slower way of producing fashion.

A Message to Future Learners

Start with the end of life, not the aesthetics. If you design how a product will be repaired and disassembled, sustainability becomes natural. Don’t aim for perfection — aim for improvement at every prototype.
