“…The POP category also had the highest value for the Windrow Composting mode, however, only one study was found using this method and impact [48]. For the OLD category, the highest value was found in Industrial Composting and Passive-aerated Static Piles, mainly due to the high consumption of fossil fuels and electricity required for large-scale plants operation, use of extra auxiliary materials (equipment), use of energy for material preparation (shredding), and gas emissions from composting process [6,39].…”

“…When composting plants are poorly managed, low turning frequency and non-uniform aeration can emit GHG emissions (CH 4 and N 2 O), contributing to GWP [42,47]. Another process responsible for the aggravating GWP results is the use of machines that use fuel and electricity from fossil sources, due to the emissions of CO 2 [6]. In Cadena et al [21], the use of fuel and electricity represented the highest contribution to the Global Warming Potential, Photochemical Oxidation, Human Toxicity and Ozone Layer Depletion due to the CO 2 derived from fossils, VOCs and fossil consumption [56].…”

“…Composting is an appropriate way to generate a product from biowaste that replaces non-renewables with biological resources, according to the principles of the Circular Bioeconomy [4,5]. Diverting waste to composting has the potential to alleviate the impact on climate, reduce greenhouse gases emission, and offer great potential in establishing a circular waste management system when based on a well-planned waste management strategy [6]. Any amount of homemade compost is important to decrease the amount of organic waste that is sent to the landfill.…”

Systematic Review and Meta-Analysis on the Use of LCA to Assess the Environmental Impacts of the Composting Process

Following the industrial revolution, major economic and populational growth took place, and, therefore, solid waste generation increased exponentially. Nowadays, waste management still generates major impacts because the current wide offer of waste management strategies includes many solutions that produce suboptimal results, such as landfill or waste incineration. From a circular economy perspective, composting is a potentially sustainable option to treat the organic fraction of solid waste and has the advantage of recycling many organic compounds that can be reintroduced into the natural processes. This study aimed to provide a meta-analysis using the Life Cycle Assessment (LCA) method to evaluate the impacts of composting by performing a systematic literature review of the diversity of approaches and assessing environmental impacts. The results of the impact assessment were highly dependent on the choices made over the system boundary and the functional units. The most cited environmental impacts were Global Warming Potential, Acidification Potential, Eutrophication Potential, Photochemical Oxidation Potential, and Ozone Layer Depletion, as gaseous emissions from the transport and decomposition represent the main contributors to these categories. Using a smaller dataset and evaluating the use of the CML method and the most cited impacts categories, it was found that In-vessel Composting and Home Composting were considered the best environmental options among the studied composting methods. Composting environmental impacts were also highly related to the use of non-renewable energy sources, which puts composting at a disadvantage when compared with the use of anaerobic digestion. Such results emphasize the benefits of using these waste management technologies as complementary instead of substitutes.

“…Most of their food waste and green waste are diverted from landfills through composting. UM used the Takakura composting and aerated pile composting methods for food waste and green waste [70,74]. From the composting process, about 0.15 kg of compost was produced from 1 kg of food waste after 60 days [75].…”

Composting and anaerobic digestion have emerged as better options for managing food waste and sewage sludge at the campus level. This review highlights the characteristics of food waste and sewage sludge from various global higher education institutions. The composting and anaerobic digestion processes of food waste and sewage sludge will be reviewed and evaluated. Also, the adoption of composting and anaerobic digestion at various campus levels has been reviewed. The challenges and future direction, focusing on managing university campus composting and anaerobic digestion, are discussed as well. This review paper will significantly contribute to the understanding of the potential for managing and handling campus waste in a natural-friendly manner.

“…Estudios como el realizado por Van Haaren et al (2010) han determinado que el compostaje aerobio con ingreso diario, minimiza la producción de metano con respecto a las emisiones generadas en los sitios de disposición final cuando esta fracción no es separada; por su parte Martínez et al (2016), establecieron que el 47.11 % de los RO que llegan a un relleno sanitario podrían ser transformados en composta, generando múltiples beneficios entre los que destacan: la reducción de los costos de operación, incremento de su vida útil y la disminución de las emisiones de metano (al favorecer el predominio de procesos aerobios), con el subsecuente uso de abonos orgánicos para la recuperación de áreas verdes. Todo ello bajo un sistema de gestión circular (Tchakpa etal., 2013, Ng et al, 2021.…”

El compostaje de residuos orgánicos es una práctica emergente en hogares e instituciones educativas que favorece la transferencia de conocimientos a conductas tendientes a minimizar los impactos ambientales y riesgos a la salud humana. La propuesta de investigación consistió en implementar un modelo de transición circular con perspectiva de ciclo de vida para promover el conocimiento adquirido a estudiantes de la Licenciatura en Ciencias Ambientales y la conducta ecológica en un entorno doméstico durante el confinamiento por la pandemia COVID-19. Las etapas del modelo son: generación, colecta, separación, tratamiento de compostaje y caracterización fisicoquímica. Como resultados se obtuvo que el proceso tuvo una eficiencia del 48 % con respecto al peso fresco y una calidad adecuada acorde a la normatividad oficial. La conducta ecológica adquirida en el grupo de estudiantes confinados en sus hogares, se evaluó mediante encuestas de percepción sobre acciones y actitudes realizadas con respecto al manejo doméstico de los residuos, arrojando un 59% como una experiencia exitosa. La perspectiva de ciclo de vida para el tratamiento de los residuos orgánicos orienta a contrarrestar el impacto ambiental, así como un enfoque de economía circular en la gestión integral dentro y fuera de la institución.
