This study explores bio-oil production from corn cobs via hydrothermal conversion. Optimal conditions yield 23.9% bio-oil, and adding crude glycerol boosts the yield to 36.3% while enhancing oil quality and gas composition.

This study focused on reducing water and raw material use in leather tanning processes through chromium precipitation and water recirculation during the liming and tanning stages. By treating and reusing wastewater, the process achieved over 99% chromium removal and allowed direct recirculation of liming water up to three times without affecting leather quality.

My thesis examined phosphorus (P) pollution in two agricultural watersheds in Kansas with different levels of animal farming: Upper West Emma Creek (UWEC) and Red Rock Creek (RRC). I analyzed P dynamics in stream sediments and upland soils to assess their contribution to water quality degradation. Results showed that stream banks, especially in UWEC, were major in-stream P sources due to erosion, while upland soils—particularly manure-amended fields—were key contributors in R

As part of a multidisciplinary research team at Universidad Pontificia Bolivariana, I contributed to a technical and economic evaluation of water reuse technologies in small and medium-sized industries from the food, textile, leather, and electroplating sectors in the Aburrá Valley.

This article presents the technical and economic evaluation of a plant designed to produce lightweight expanded aggregates (ALER) from sewage sludge generated in Medellín’s wastewater treatment plants. Conducted by Universidad Pontificia Bolivariana, the study proposes a sustainable alternative to landfill disposal by transforming sludge into a raw material for eco-friendly construction.

The article presents the results of a project developed by Universidad Pontificia Bolivariana and funded by Colciencias. This project aims to use sludge from the paper industry in the production of construction materials.
