摘要：

Vegetable or synthetic lubricants, also called biolubricants, are less harmful to the environment. In order to quantify their biodegradability, some tests are able to predict how long oil/lubricants will take to be degraded in the environment. This study proposes to evaluate the biodegradability of bio-based lubricants using a bio-kinetic model (without microorganisms), comparing their performances with fresh vegetable oil and mineral oil. The results are presented through an Effective Composition for Biodegradation (ECB), half-lives and biodegradation time profile. The synthesized biolubricants showed ECB values closer to vegetable oil than mineral oil. Half-life times are approximately 12 days for fresh vegetable oil, around 20-30 days for the biolubricants, and over 200 days for the mineral oil. (C) 2015 Elsevier Ltd. All rights reserved.
