Towards development of biogas production for New Zealand on-farm greenhouse gas reduction
… and quantifying the environmental benefits. Physicochemical analyses revealed that New Zealand dairy goat manure had higher initial bioconversion potential (16% volatile solids) than cow manure (10%) but slower hydrolysis rates due to complex lignocellulosic structures. This resulted in its …

Development of consumer accepted low salt and low fat traditional Irish processed meats
Irish consumers (n = 1045) were surveyed with respect to their attitudes towards healthier food consumption, particularly in relation to salt and fat reduction. It appears educational campaigns have generally been adopted by respondents, as only a minority were not concerned about their diet; …
