Chardust Ltd. ( is responsible for seedball production and, some 20 years ago, started what is now a thriving industry in East Africa: manufacturing eco-friendly briquettes from salvaged charcoal vendor's waste. Chardust started coal mining in some of the highest-density and lowest-income urban areas of Nairobi in 1996.



Charcoal has been a valued urban domestic fuel for centuries and remains the go-to fuel of choice for the majority of Nairobi residents to this day. At least 750,000 kg of rough unprocessed  lump wood charcoal is consumed within Nairobi daily, and of that amount 15% is fines and chips: charcoal vendors waste.

Another use for salvaged charcoal waste is Biochar. Charcoal dust and chips have well documented soil improvement characteristics, particularly in acidic tropical soils ( This is where charcoal vendor's waste meets tree and grass seeds to produce Seedballs using production techniques developed by Chardust in partnership with Cookswell Jikos. The recycle circle is complete with the use of salvaged urban biochar to protect and nourish seeds delivered to areas that were, in most cases, deforested for fuel.

Charcoal mining to be precise. Elsen had discovered that beneath every long-established charcoal sales area scattered throughout most of Nairobi there were literally thousands of tons of well-preserved discarded charcoal dust 'waste'- some of it dating back to the early 1900's as evidenced by old coins recovered during 'mining' the sites.



This amounts to well over 100 tons per day of high energy combustible charcoal. and now in 2017 there are some 50 briquetting facilities of various sizes and sophistication following Chardust's lead and methods. We are happy to see that most of this 'waste' is no longer wasted. VWB- Vendor's Waste Briquettes- are now part of the charcoal value chain.
