[Stoves] Coffee waste and briquettes

Wed Jan 3 02:27:37 CST 2018

Hi Nikhil,

I wasn’t here in 2003 but these power cuts are said to be the worst on record. The problem with being over-reliant on hydro-electric all from one lake/river. Plans are ongoing for a coal station on the SW border with Mozambique where Tete province has huge coal deposits plus a railway line through Malawi to the Nacala port in Northern Mozambique. As a political fix they are importing approx. 40MW of diesel gensets and once installed ESCOM will hike tariffs by 25%, prices have historically been below the cost of production.

Most urban middle class cook with charcoal and some electricity, and LPG usage is still low. Induction cookers would be one answer but better to go after inefficient fridges and aircon, plus the habit of leaving lights on during the day. They already had a CFL switch out programme.

I was in Malawi at the time of power outages in 2003. 

I recommended that this time around, they should try distribution of electric induction stoves to manage peak loads. What do you think -- for low- and middle-income areas of Blantyre, in particular? 

Economics look good, compared to charcoal, unless Escom has hiked up the tariff or introduced ToU tariffs.

Dear List,

Greetings from a rainy and power outage ridden Malawi. I’m after a quick overview of using coffee waste to make briquettes if anyone has the knowledge please. I’m just finishing up some work in Timor-Leste and there’s a lot of coffee waste which could be put to good use. So what is a typical mix of briquette feedstock if coffee husks are involved (approx. 7cm dia. extruded) and what are the limitations of using this material? (The waste stream is heavily seasonal and market dynamics lean towards an urban briquette market. There is very little charcoal used)
