Energy
Resources

What it does:

Reduction of methane formation in the covered slurry tank as well as reduction of nitrous oxide

How to get it done
What is to be done
Identification of potential solution that fits purpose and definition of investment plan
Impact
High
Potential to be realised and possible conflict of interest
Potential investment can be substantial
Roadmap and time horizon
1-5 years
Cost
Interest rate/depreciation of investment
Investment
Investment between €30-230/m3 of slurry tank to be covered
Financing
Bank loan, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
High impact with reduction of methane formation in the covered slurry tank as well as reduction of nitrous oxide. Will lead to increased slurry nutrient content
What to measure
Slurry tank covered in m3 and additional nutrient content
How to measure
Covered m3 of slurry and respective modelling. Repeated lab analysis of slurry before and after coverage

D2 – Manure storage and Compostation

Description:

Use of appropriate composting methods for manure to reduce emissions and to promote soil quality

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

Reduction of methane formation in manure as well as reduction of nitrous oxide and promotion of humus build-up

How to get it done
What is to be done
Determination and implementation of the appropriate procedure together with the local extension service
Impact
Medium
Potential to be realised and possible conflict of interest
Potential investment is substantial and implementation is labour intense. Operations are demanding. There might be conflicts with local rules and building codes to get operations realized
Roadmap and time horizon
1-5 years
Cost
Compostation site and machines as well as necessary labour. Need additional substrate for compostation that is paid for to break even
Investment
Investment between several €10k and €100k to get up and running
Financing
Bank loan, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
Medium impact trough reduction of methane formation in manure as well as reduction of nitrous oxide and promotion of humus build-up. Can lead to higher soil fertility and higher crop yields
What to measure
Tons of compost produced and its use as well as kg of mineral fertlizers reduced
How to measure
Tons of compost produced and applied to be recorded as well as mineral fertilizer being replaced
Solution providers
GujerInnoTec AG (www.gujerinnotec.com)
Farmer acceptance
Low (14% of farmers in AgroCO2ncept have implement measures by 2020). Acceptance increases if humus build up measured

D3 – Slurry tank in soil

Description:

Use of appropriate composting methods for manure to reduce emissions and to promote soil quality

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

By storing the slurry in the soil, it is cooled to below 10°C and microbial methane-generating processes are slowed down

How to get it done
What is to be done
Determination and implementation of the appropriate procedure together with the local extension service
Impact
Medium
Potential to be realised and possible conflict of interest
Potential investment is substantial. There might be conflicts with local rules and building codes
Roadmap and time horizon
1-5 years
Cost
Interest rate and depreciation of investment
Investment
Investment of several €100k
Financing
Bank loan, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
Medium impact trough reduction of methane formation in manure. Will lead to higher nutrient content of manure and respective reduction of mineral fertilizers
What to measure
m3 of slurry tank in soil and its use as well as kg of mineral fertlizers reduced
How to measure
m3 of slurry from tank in soil applied to be recorded as well as mineral fertilizer being replaced
Solution providers
Local construction company, LBG (www.lbg-bau.ch)
Farmer acceptance
Medium (50% of farmers in AgroCO2ncept have implement measures by 2020)

D4 – Slurry tank aeration

Description:

GHG emissions are reduced by appropriate aeration measures of the slurry (e.g. weekly stirring)

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

GHG emissions are reduced by appropriate aeration measures of the slurry (e.g. weekly stirring)

How to get it done
What is to be done
Adoption of daily/weekly operations and potential update of slurry tank installations
Impact
Small
Potential to be realised and possible conflict of interest
Easy to implement. Potential investment is minor
Roadmap and time horizon
1-5 years
Cost
Machines, working h and energy use for stirring/ventilation
Investment
Investment of €0-5’000
Financing
Own ressources
How to measure, assess impact and whom to talk to
Impact
Small impact trough reduction of methane formation in manure and nitrous oxide emissions. Will lead to higher nutrient content of manure and respective reduction of mineral fertilizers
What to measure
