“…7 The global PSW generation rate was 1.3 billion tons per year in 2015, with an estimated increase to 2.2 billion tons per year by 2025, accompanied by an acceleration in the per capita waste production rate from 1.2 to 1.42 kg/person/day. 8 The excessive use of plastic materials in numerous daily and industrial activities, along with the production of vast quantities of PSW, contributes to water, air, and land pollution. 9−13 In addition, PSW tends to accumulate on beaches, diminishing their aesthetic and recreational value.…”

“…This widespread production and use of plastics has also led to environmental issues associated with the disposal of plastic solid waste (PSW). , For instance, approximately 8300 million metric tons of plastics have been produced until 2015, leading to generation of 6300 million metric tons of PSW between 1950 and 2015, of which 9% was recycled, 12% incinerated, and 79% disposed of in landfills or the natural environment . The global PSW generation rate was 1.3 billion tons per year in 2015, with an estimated increase to 2.2 billion tons per year by 2025, accompanied by an acceleration in the per capita waste production rate from 1.2 to 1.42 kg/person/day …”

Plastic and biomass waste pose a serious environmental risk; thus, herein, we mixed biomass waste with plastic bottle waste (PET) to produce char composite materials for producing a magnetic char composite for better separation when used in water treatment applications. This study also calculated the life cycle environmental impacts of the preparation of adsorbent material for 11 different indicator categories. For 1 functional unit (1 kg of pomace leaves as feedstock), abiotic depletion of fossil fuels and global warming potential were quantified as 7.17 MJ and 0.63 kg CO 2 equiv for production of magnetic char composite materials. The magnetic char composite material (MPBC) was then used to remove crystal violet dye from its aqueous solution under various operational parameters. The kinetics and isotherm statistical theories showed that the sorption of CV dye onto MPBC was governed by pseudo-second-order, and Langmuir models, respectively. The quantitative assessment of sorption capacity clarifies that the produced MPBC exhibited an admirable ability of 256.41 mg g –1 . Meanwhile, the recyclability of 92.4% of MPBC was demonstrated after 5 adsorption/desorption cycles. Findings from this study will inspire more sustainable and cost-effective production of magnetic sorbents, including those derived from combined plastic and biomass waste streams.

“…It involves the oxidation of combustible materials present in MSW, generating high-temperature heat that can be utilized for electricity production (24). Additionally, it significantly reduces the weight and volume of MSW, by approximately 80-85% and 90-95%, respectively, reducing the need for landfills (25)(26)(27). However, it presents challenges due to the variable composition of waste and the presence of hazardous components (28).…”

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.

The current study aimed at evaluating the effects of different sewage sludge (SS) amendment rates as biofertilizers on growth of Corchorus olitorius plants and soil properties, with an emphasis on heavy metal (HM) allocation in plant parts and postharvest soil. Then, the soil was supplemented with various SS rates (0, 10, 20, 30, and 40 g kg −1). The effects of these SS amendment rates on different growth parameters of Corchorus olitorius and soil properties were investigated. The SS amendment rate of 20 g kg −1 triggered the highest growth rates of Corchorus plants. Micronutrient HMs, including Co, Cu, Mn, and Ni, increased in the shoots of plants grown in soils amended with 20 g kg −1 , but with levels sufficient for normal plant growth and below the phytotoxic limits. The sludge application significantly increased the content of organic matter in postharvest soil from 1.38 to 4.83% at the amendment rate of 20 g kg −1. Furthermore, our data showed that the quantities of the estimated HMs remaining in postharvest soils were below (Cu, Fe, Mn, Mo, Zn, and Pb) or within (Co, Ni, Cd, and Cr) the maximum permissible concentrations in agricultural soils at all of the SS amendment rates. Taken together, our findings suggest that soil application of SS can provide a sustainable safe practice for SS disposal and improve plant growth, while exerting no environmental threats provided there is no accumulation of HMs to toxic levels in shoots of the grown plants or in the amended soils.
