This paper investigates the practical implementation of transitioning to a circular economy through network governance in conjunction with public governance. The research focuses on a comparative, longitudinal analysis of three Dutch product chains (mattresses, concrete, and textiles) from 2016 to the present. The study based on action research, utilizes documents, reports from all meetings, and personal observations. Drawing from the fields of public administration and transition management, the paper addresses tw [...]

Fusarium is the most common soil-borne pathogen that causes wilt in many plant crops, among which the tomato is one of the most susceptible crops. This experiment is conducted to analyse the impacts of inorganic carbon compounds i.e., calcium carbonate CaCO3, sodium carbonate Na2CO3 and potassium bicarbonate KHCO3 on the growth of Fusarium oxysporum f. sp. lycopersici (FOL) causing wilt in tomato plant in different culture media including Malt Extract Agar (MEA), Potato Dextrose Agar (PDA) and V8. Three concentrati [...]

Hydrogels are three-dimensional, hydrophilic networks of polymers with a high water absorption capacity. We investigated the removal of monovalent cationic dye, methylene blue, from aqueous solutions by a polyvinyl alcohol/Sodium alginate/Starch mix hydrogel to discover a solution to the environmental waste-water problem. By applying a gamma radiation dose from a Co-60 source without adding a hazardous cross-linker, a novel PVA/SA/Starch mix hydrogel was synthesized. The effects of factors like irradiation dose and [...]

Urban heat island (UHI) effects are evident in many cities globally. Studies have revealed that UHI impacts air pollution and vice versa. However, it is observed that these two severe problems are addressed independently instead of interrelatedly. The study seeks to provide an in-depth understanding of the relationship between air pollution and heat and how they constantly shape urban areas for planning and future research purposes. A global shift from sustainable planning practices to building urban resilience exi [...]

Decomposition of spent coffee grounds (SCGs), a byproduct of brewing coffee, in disposed landfill sites releases significant amounts of potent greenhouse gases. This study aims to investigate the maximum recycling proportions of SCGs, a nonconventional filler material, for permeable interlocking concrete paving (PICP) blocks. These blocks have a porous structure that helps mitigate surface ponding while maintaining sound structural performance. Using Scanning Electron Microscope image analysis, the water absorbency [...]

Currently, almost half of the human population is at risk of acquiring dengue. Other emerging pathogens affecting human populations transmitted by Aedes (Stegomyia) aegypti are chikungunya and Zika viruses. People who live in poor areas are more susceptible to be infected by these diseases. The lack of selective garbage collection and inadequate water storage are important factors in the dynamics of vector-borne transmission. This study took place in Estrutural City, the poorest city in Brasilia, Brazil, which host [...]

The environmental impact of emissions appears to be increasingly important for food, particularly those of animal origin. The LCA (Life-Cycle Assessment) method, an internationally standardized method used to calculate the environmental impact of goods or services, in the carbon footprint, does not take into account the carbon set and consequently the subtraction of carbon dioxide by the plant biomass whether or not aimed at the production of food of animal origin. This methodology could overestimate the carbon dio [...]

Carnauba straw (Copernicia prunifera), residual biomass derived from wax extraction, was evaluated as a potential feedstock for bioenergy production. The characterization was carried out using elemental analysis, proximate analysis, Higher Heating Value (HHV), FTIR spectroscopy, SEM, and FRX. The carbonization, using a Muffle Furnace, was applied as a thermal conversion technique to improve the fixed carbon content, and preliminary densification was done to assess the potential for future production of briquettes.

Sasthamkotta Lake eco-region is a freshwater Ramsar site in Kerala, India. Eco-regions are ecologically and geographically defined larger land or water mass areas with a characteristic assemblage of the ecosystem and significant biodiversity. A decentralized and locally self-sustaining mechanism has been achieved in managing this eco-region by a participatory model through a joint Biodiversity Management Committee (jBMC) constitution. BMCs are custodians of the environment, and biodiversity, confined to a village/P [...]

Cyanobacteria have great potential as a platform for biofuel production because of their fast growth, ability to fix CO2 gas, and genetic tractability. They also preserve the sustainability of an ecosystem without harming the environment. High-performance biofuels made from cyanobacteria can be utilized as a base for the production of green energy. Although a lot of studies have been conducted where plants and crops are used as the source of energy, cyanobacteria have been reported to have a more efficient photosyn [...]
