(Introduction):

Life Cycle Analysis is a powerful and well-recognized methodology to determine a product’s environmental impact

(Objective):

The aim of this research was to evaluate the impact of wooden pallets on climate change.

(Methodology):

The scope of the system ranges from land preparation to establish the plantations to the arrival gate at the fruit packing house. Two functional units were assessed: a) a pallet with commercial dimensions for handling of agricultural products and b) a cubic meter of wood to produce pallets. The study included data from the 2014-2017 period, and life cycle results included a whole rotation equivalent to 12 years for the gmelina (Gmelina arborea Roxb) plantations. Two product systems were evaluated: using biomass in the heat treatment and using LP gas.

(Results):

The former presented a slightly smaller potential impact. In both cases, the diesel combustion associated with roundwood transport was the most emissions intense stage, releasing approximately 1.61 kg CO2-eq pallet-1 and 43.22 kg CO2-eq m-3. Diesel is the primary source of greenhouse gas emissions in all life cycle stages, releasing 2.31 kg CO2-eq pallet-1 and 86.57 kg CO2-eq m-3.

(Conclusions):

Opportunities to improve the product’s environmental performance include using more efficient loading vehicles and reducing the distance between forest plantations and the sawmill.
