A Case Study in Sabanalarga, Colombia
Published on 2026-02-04 by Lina Henriquez Sarmiento, Hugo Hernndez, Anderson Nieto Granados, Jorge Rodas, Andrea Liliana Moreno-Ros, Andreas Hasse, Diana Pinto, Claudete Gindri Ramos @MDPI
Abstract: Technosols are artificial soils produced from organic and inorganic solid waste to improve soil fertility and functionality. This study evaluated the potential of Technosols produced from household waste from the Altos de Guadalupe residential complex in Colombia to fertilize green areas and promote the growth of Duranta erecta. A physical characterization of waste from 46 houses was performed to estimate per capita production (PPC) and waste composition. Technosols were produced in 20, 50, and [...]
Our summary: Technosols made from household waste were evaluated for their ability to enhance soil fertility and promote plant growth in Sabanalarga, Colombia. The study found that Technosols significantly improved soil organic matter and nutrient availability, leading to increased plant height and root dry matter. These findings support the use of Technosols in urban agriculture, aligning with circular economy principles and sustainable development goals.
