Hi, I am Humph
I am going to tell you all about my new boilers.
I have purchased lots of coffee waste. That's the grinds you were all throwing away.
I send them to the drying plant. Leaving just enough moisture for the pelletier to turn them into combustable fuel. The pellets are then delivered to the boiler by my specialist truck. The boiler burns only my brand new coffee waste pallets. The heat created in the boiler is circulated around the whole building and provides as much heating as you want. As much running hot water as you want. And allows you to make another cup of coffee in the warmth of your own home, then the coffee grains come back to me to start again.
Recycling in action...
