Pig slurry options too dear

LAND spreading is likely to be the most cost effective method of recycling pig manure nutrients in Ireland for the foreseeable future, according to Teagasc resear- chers.

Their cost analysis has shown that alternative technologies are not currently cost effective in Ireland, but they may have future potential.

For example, anaerobic digestion would be cost effective on large units (2,000 sows plus), or if centralised treatment plants were developed, and if the renewable energy feed in tariff for energy sold to the grid was increased.
