Life cycle assessment of spray dried soluble coffee and comparison with alternatives (drip filter and capsule espresso).

摘要: Abstract This paper aims to evaluate the environmental burdens associated with spray dried soluble coffee over its entire life cycle and compare it drip filter capsule espresso coffee. It particularly identify critical issues responsibilities along whole chain of assessment (LCA) specifically uses foreground data obtained directly from manufacturers suppliers. Aside energy consumption greenhouse gases emissions, water footprint is also studied in detail, including regionalization impacts based on ecological scarcity method 2006. Other impact categories are screened using IMPACT 2002+ method. The overall LCA results for a 1 dl cup amounts approximately 1 MJ primary non-renewable consumption, emissions 0.07 kg CO 2-eq , between 3 10 l non-turbined use, depending whether or not cultivation irrigated wet treated. When considering turbined water, use can be up 400 l per cup. Pouch – lesser extent metal packaging alternatives show lower than glass sticks. On average, about one half occurs at stage under control producer suppliers (i.e., during cultivation, treatment, processing, distribution, advertising) other controlled by user (shopping, appliances manufacturing, waste disposal). Key parameters amount extra boiled efficiency cleaning phase, not, as well type fertilizer used field. contributes 10% impacts. Compared alternatives, less has coffee, latter having highest basis. study shows that broad approach needed help industry minimize related their products. Including all processes system necessary i) get comprehensive product respect sustainable production ii) share stakeholders responsibility cycle, iii) avoid problem shifting different stages.
