Resumen

In the subregion of La Paz Province in eastern Antioquia, Colombia, Hydrangea floriculture has boosted economic and social development, generating high value in the territory; however, there are still environmental gaps to be established as a sustainable activity. This study analyzed some environmental aspects of cultivation and it based on the life cycle assessment under ISO 14040/14044 standards. The functional unit defined was 1 kg of Hydrangea stems, grown on a small farm of 0.45 ha and the limits selected were on gate-to-gate. The Environmental impacts were evaluated using the CML methodology, Umberto LCA software and the Ecoinvent 3.8 da-tabase. The most significant contribution to these impacts were ozone depletion, terrestrial eco-toxicity, and photochemical oxidant formation, which comes from the application and pretreat-ment of chemical fertilizers and pesticides, plant residue generation, and fossil resource materials such as polymers and fuels. In addition, two cleaner production initiatives were considered: Composting plant residues for fertilizer (the use of 100% and 50% composting) and Integrated Pest Management with biological control and natural agents to reduce pesticide use (30% and 50% of chemical pesticides). And the integration of both actions, with 50% composting and 30% sub-stitution of chemical pesticides. The environmental impact was reduced by 19.63% and 9.97%, respectively for composting, 6.62% and 11.03%, respectively for biological control and 16.59% for integration of actions. The two alternatives allow improving the crop, contributing to minimize environmental impacts, optimizing the use of inputs and fertilizers and contributing to the sus-tainable development of floriculture.
