Destruction of methane from piggeries using engineered biodigestersThrough these projects, pig manure is directed into a biodigester. A biodigester is an oxygen-free tank where micro-organisms break down the waste. Methane is produced through this process which is collected and burnt.More Details
Destruction of methane generated from dairy manure in covered anaerobic ponds
This method applies to projects that reduce the methane generated from manure in dairy production systems by collecting emitted greenhouse gas from covered effluent ponds and combusting it through the use of a flare and/or an internal combustion engine and/or gas boiler.
The project requires:Installing and operating covers and gas capture and combustion equipment to existing uncovered effluent treatment ponds, and/or
Replacing of conventional ponds with covered pond systems.
Destruction of methane generated from manure in piggeries V1.1More Details
The project requires installing and operating gas capture-and-combustion equipment and installing new covered lagoons or covering existing uncovered treatment lagoons. The methane component of the biogas is combusted using flares, and/or an electricity generation system, and/or a gas boiler.
Reducing greenhouse gas emissions in milking cows through feeding dietary additivesMore Details Fact Sheet
This method applies to projects that reduce methane generated from manure by feeding eligible additives to milking cows.
Eligible additives include canola meal, cold-pressed canola meal, brewer's grain, hominy meal or dried distiller's grain, and are used to increase the fat content of a milking cow's diet.
The project must:only occur on dairy farms, including organic dairy farms, where milking cows are pasture grazed for at least nine months of the year, and maintain dietary fats and oils below seven percent of the total dry matter feed.
Reducing greenhouse gas emissions in beef cattle through feeding nitrate containing supplementsMore Details Fact Sheet
Projects using the feeding nitrates to beef cattle method reduce greenhouse gas emissions from pasture-fed beef cattle by substituting urea supplements with a nitrate supplement in the form of lick blocks.
Urea is often used to increase the amount of protein in the diet of pasture-fed beef cattle. It also makes pasture easier for the cattle to digest, so they tend to eat more of it, which in turn means they produce more methane. When some or all of the urea is replaced by nitrate supplements, cattle produce less methane.
The CFI Beef Nitrates Calculator has been developed to assist project proponents to estimate the effect of feeding nitrate supplements to pasture fed beef cattle to reduce greenhouse gas emissions.
It is a requirement that all projects under the Determination use the Beef Nitrates Calculator to estimate emissions reductions for reporting purposes.
