The world is changing rapidly. In particular, the large increases in fuel costs and the pressures to reduce carbon emissions are bound to have a significant impact on the food chain. It is likely that over the next 10 years the costs of food processing and transport will increase, as will demands to use more land for non-food crop production. This will be compounded by the costly energy requirements of modern intensive agriculture, including mechanized activities and the use of fertilizers. These drivers, in conjunction with the 'waste hierarchy' will add further pressure to ensure that the majority of food processing and food-chain co-products are fully exploited. In order to evaluate this complex arena from environmental and economic perspectives, the demand for user-friendly LCA is likely to increase.
