El crecimiento constante en la generación de residuos urbanos a nivel global ha generado una creciente necesidad de abordar su gestión de manera sostenible. A pesar de que la conversión de estos residuos en energía ha demostrado ser efectiva en varios países, su implementación en Colombia aún se encuentra en una etapa incipiente. En este estudio, se llevó a cabo un análisis bibliométrico y una revisión sistemática exhaustiva de la literatura con el propósito de evaluar las tecnologías de valorización de los residuos sólidos urbanos, así como su potencial integración en biorrefinerías en el contexto colombiano. Entre las tecnologías más relevantes identificadas se encuentran la incineración, la gasificación, la pirólisis, la digestión anaeróbica y la recuperación de gas de vertedero.La Digestión Anaerobia destaca como una opción atractiva debido a su versatilidad. No obstante, se reconoce la necesidad imperante de adoptar una elección dinámica de tecnologías, considerando la diversidad de contextos y condiciones específicas en Colombia. Además, la gasificación y la pirólisis emergen como opciones viables, cada una con sus propias ventajas y desafíos, reflejando la complejidad y variabilidad en la gestión de residuos. En relación con la recuperación de gas de vertedero, se subraya su importancia como instalación esencial en vertederos controlados, desestimando la consideración de una alternativa independiente. Si bien la literatura sugiere que la incineración se percibe como menos favorable en términos sociales, económicos y ambientales, es crucial reconocer la dinámica y especificidad de cada situación. La elección de tecnologías debe ser adaptativa y orientada por un enfoque contextual que considere la heterogeneidad en la composición de residuos, infraestructura disponible y otros factores que varían significativamente de un escenario a otro. Este enfoque dinámico y adaptativo es esencial para abordar la complejidad de la gestión de residuos urbanos y encontrar soluciones sostenibles en el contexto colombiano.

“…Gonzalez et al 2019, used glycerol (varying between 0-5% wt.) as a binder for fallen leaves biomass and observed increment of CH4 by 25% and H2 by 20% compare to biomass without a binder [27]. Shone & Jothi, 2016 considered the leaves of Teak and Rubber tree having tapioca starch as a binder at different biomass to binder ratio [28].…”

Present study concerns with the production of H2 rich product gas by thermochemical energy conversion having biomass gasification as a route for the four biomasses i.e., Kasai Saw Dust, Lemon Grass, Wheat Straw and Pigeon Pea Seed Coat. The biomasses are from the family of woody biomass, grasses, agricultural waste and food process industry wastes. Waste engine oil as an additive is used, which also acts as a binder. Air gasification and Air-steam gasification is applied and compared for product gas composition, hydrogen yield and other performance parameters like lower heating value, energy yield. Product gas constituents, hydrogen production is examined with different steam to biomass ratio (S/B ratio) and equivalence ratio. The equivalence ratio varies from 0.20-0.40 and the steam to biomass ratio varies between 0-4. The waster engine oil is mixed with the biomasses with different percentage of 5 and 10 wt%. For enhancement of feedstock quality palletization process is applied. The H2 yield is greatly affected by the equivalence ratio. Results show maximum H2 production and higher calorific value of product gas at an air to fuel of 0.26 for all the biomass pallets. Also, the S/B ratio observed as important aspect for hydrogen enrichment. Hydrogen yield is maximum at 2.4 steam to biomass ratio. This study considers the rarely studied Indian biomasses with waste engine oil as an additive for hydrogen-rich product gas production and will be beneficial for small scale hydrogen-rich syngas production considering the central Indian region originated biomasses. Statement of Novelty (SON):Research work belongs to eco-friendly use of rarely studied Indian biomass pallets. Equivalence air to fuel ratio (E/R ratio), steam to biomass ratio (S/B ratio) and waste engine oil as additive have been considered to upgrade H2 content and Calorific Value (CV) of the product gas. Novelty of work include use of waste engine oil as additive to make biomass pallets.

Evaluation of Urban Tree Leaf Biomass-Potential, Physico-Mechanical and Chemical Parameters of Raw Material and Solid Biofuel

et al. 2021

The paper presents the results of research aimed at evaluating the possibility of using selected tree leaf species to produce solid biofuels. The possibility of production of qualitative solid biofuels from urban tree leaves meets the expectations of the municipal sector. Collection of tree leaves in urban areas is very often necessary for road safety reasons, the need to collect biomass rich in dust and pollution as well as biomass infested with pests. The production of solid biofuels from tree leaves allows for effective management of this raw material with energy recovery. The performed research indicates such a possibility, and the obtained ash is used as a soil improver. The conducted research showed that the biomass of leaves of five tree species used in the experiment can be a source of raw materials for production of qualitative biofuels. The obtained pellets were characterized by properties comparable to those of classical wood pellets. The lower heating value of the obtained pellets ranged from 14.5 to 15.5 MJ∙kg−1. Physical properties of the obtained pellets described by bulk density (BD 600–660 kg∙m−3), mechanical durability (DU 90–96%), moisture (Mar 10–12.5%) indicate that these products can be used in existing combustion equipment. Preliminary analysis of the obtained ashes (determination of ash melting point, bulk density) indicates that they should not cause difficulties in ash removal systems from the combustion chamber.
