Caffe Inc., Bonne Suits & Boro Atelier launches their suits made through a unique circular supply chain in the Netherlands with support of the Circulaire Ketenprojecten


Caffe Inc. a Dutch start up based in Amsterdam, creates the world’s first natural dye by upcycling the waste stream of spent coffee grounds, a large but overlooked waste stream. Collaborating with Bonne Suits and Boro Atelier, the iconic gender neutral Bonne suits are available for purchase in three different shades via Bonne Suits.


*These natural dye suits using Caffe Inc. coffee colorants are limited edition.

The world’s first ink from coffee by-product

Please get in touch if interested in becoming a launching customer for our natural ingredients by emailing to

Caffe Inc. is the only company worldwide commercially offering bio-based colorants and printing inks. We have been working on our R&D pipeline since 2019. This pipeline refers to the development of natural dyes from coffee by-product that goes to waste. A resource that is abundant in coffee-addicted Europe a resource that had already traveled from all over the globe. A resource in which its high value is being wasted to organic digestion. Caffe Inc. will become the first company to validate this innovative product and is working tirelessly to achieve continuous production and new shades.

With much experimentation and adjustments of the colorants and dying technique, three very different tones were achieved. The coffee-dyed Bonne Suits are available in three colour shades: Mocca, Charcoal and Raw Green.

Environmental impact of synthetic dye

The textile industry is among the world’s most significant environmental polluters, particularly due to the use of synthetic dyes. These dyes, while offering a broad range of colours, are toxic and adversely impact all forms of life. The presence of harmful substances like naphthol, vat dyes, nitrates, acetic acid, heavy metals, and various non-biodegradable dyeing auxiliaries in synthetic dyes leads to the extreme toxicity of textile dyeing water effluent. This pollution affects water quality, harms marine life, and can even lead to soil productivity loss. The industry’s movement towards more eco-friendly dyeing processes, such as using bio-based colors and natural mordants, is crucial in mitigating these environmental impacts. Khattab, Abdelrahman, & Rehan, (2020).


“This project makes my brand come through on the promise behind our Suits: the cup of coffee you drink in the morning, forms the basis of the suit you wear to feel beautiful and self-confident in the evening. It’s how fashion should work. This is what the future of Bonne Suits looks like: local and sustainable production.” – Bonne Reijn


The unique supply chain

Two years ago, Bonne Suits offered their suits to Caffe Inc to test the colorants on textile. Bonne Suits is a company based in Amsterdam that created its iconic BONNE suit. The BONNE suits were created to be ‘the unisex, seven-day suit’, a genderless and seasonless uniform that aims to cater to all bodies and ages. The suits’ timeless design and idealistic nature makes it the perfect testing ground for this new dyeing method. The introduction of the unique biobased/natural pigment from Caffe Inc. combines the elimination of pollutants from wastewater and the upcycling of overlooked waste into an eco-friendly upgrade on the conventional production of clothes. The first dyeing test resulted in a beautiful and promising sustainably dyed suit, but only in one colour tone.

With the ink in one hand and the suit in the other, Boro*Atelier steps in. Boro*Atelier is a social enterprise and dyeing house in Amsterdam, providing training and gainful employment to long-term job seekers and refugees, the colorants were put to the test. They focus on using only natural dyes and organic cotton for less environmental impact.

This collaboration led to a completely new, circular, Amsterdam-based supply chain for textile dyeing. It started with the help of Circulaire Projecten, but to make a tangible circular product that can be long-lasting and inclusive. An experiment, a bold testament to see if there is demand for a purpose driven industry collaboration. Re-orienting the clothing industry from a global to a local setup while upcycling waste of a common, everyday product.
