Farm margins for food production are thinner than ever. Ensure that your business is viable in the long term by generating renewable energy from your farm’s waste.
A recent survey by the NFU asked farmers in 2013, and again in 2014:
Will output prices affect you negatively in the next 12 months?
- 27% said yes in 2013
- 56% said yes in 2014
… an increase of more than 100% in just one year.
The survey also asked in 2014:
Will input prices have a negative impact on your farm business?
52% answered yes.
“This year has seen farmgate prices falling across various commodity sectors – arable, dairy, livestock and mixed – and this increased volatility has clearly impacted on our members’ confidence.”
The plight of dairy farmers has been well publicised…
- Milk prices in the UK are at their lowest level since 2007.
- In the past decade half of Britain’s dairy farms have closed.
Farmers are looking to diversify to survive.
38% of farms have some kind of renewable energy
… But potential still remains largely untapped.
On-farm renewables could provide between:
1GW could come from anaerobic digestion:
On-farm anaerobic digestion is more than an efficient waste-disposal method.
It provides additional income streams derived from on-site usage of power and heat with the export of surplus energy to the national grid.
Other financial advantages include:
Lower waste removal costs.
Reduced reliance on chemical fertilisers.
Renewable electricity – payments through the Feed-in Tariff
Renewable heat – payments through the Renewable Heat Incentive
… support is index-linked and guaranteed for a 20-year period.
Improved slurry handling.
Increased spreading windows.
Less crop taint and decreased re-grazing times.
Reduced farm environmental footprint.
To design an AD plant to utilise the 20,000 tonnes of out-of-specification vegetables produced every year, together with dual purpose crops such as sweetcorn, and an energy crop (mostly maize). Overall consumption: 1,000 tonnes of plant material per week.
100% of the output (methane) powers a 1.4 megawatt combined heat and power plant which heats the office, chills the packhouse, and feeds back into the grid.
40% of the farm’s fertiliser requirements is supplied by the digestate.
To double the size of the existing plant and construct another, using the biogas produced to run their entire fleet of over 25 lorries.
“Now we’re up and running it seems the possibilities are endless … The heat produced has the ability to heat thousands of local homes ... Compost suppliers are interested in using our digestate … Some vegetables we grow are now dual purpose … It makes business sense … as well as making it more sustainable for the future.”
