Reducing Gas Emissions from Compost with KMI Zeolite
The results showed that zeolite significantly improved the water holding capacity of the compost when compared to the control.
10% and 15% zeolite improved water holding capacity by 60 – 100% respectively!
All three containers were then sealed off, with balloons attached to the lids, with a hole allowing for the gasses to escape up into the balloons. The following images show the before and after 24 hours.
The results were clear. Even at 10% zeolite the gas emissions were almost unnoticeable in the balloon. The balloon on the lid of the 10% zeolite container only barely inflated with a slight bit of gas. The balloon on the lid of the 15% did not change at all.
The balloon on the lid of the 0% zeolite compost bucket was inflated to about 10x the size of the balloon.
Based on the results of this initial test we can see that zeolite may be able to reduce the amount of gas emitted from compost drastically.
KMI Zeolite is highly absorbent, has a high cation exchange capacity and has a negative molecular charge.
