<aside> 💡 The problem with selling the charcoal directly from the kiln is that it's not valuable. Only when the charcoal is properly refined does it become economically incentivized. That's why we had to integrate charcoal refinement as a part of this value chain.

The machine we're going to be using:

Zhongxiang Braai Birquette Charcoal Machine - Buy Charcoal Machine,Birquette Charcoal Machine,Braai Charcoal Machine Product on Alibaba.com

This machine costs around 3k USD.

Also if we plan to refine and process the sludge by ourselves, then we would have to account for operation costs.

Let's say our machine is medium.

It would costs us 3k USD upfront and then 37 USD per tonne. Not to mention we also need to account for warehousing costs.
