If the exhaust pipe is lower than the roof peak, odors from the exhaust pipe might be swept to the ground through wind downdrafting…. Continue Reading

Evaporating leachate can cool the process, too, through evaporative cooling. So do not overdo the exhaust system. To minimize the heat loss, install a fan speed controller to keep the fan speed at… Continue Reading
Increasing temperature can increase the rate of processing – within certain limits.
