Kinetics and Thermodynamics of the Pyrolysis of Waste Polystyrene over Natural Clayby
Abstract
Due to the massive increase in polymer manufacture, there has been a remarkable increase in plastic waste. With fewer landfills being used to dump plastic waste each year, it is becoming increasingly important to use effective recycling methods for plastic waste decomposition. In the present work, waste polystyrene was degraded in the presence of natural clay (K0.02, Ca0.15 [Mg0.25, Al0.69, Fe0.06], [Si2.0, Al0.6] O6.8 (O10) nH2O). The waste polymer was pyrolyzed at different heating rates i.e., 5, 10, 15 and 20 [...] 1163 9503 |
Quantification of the Carbon Sequestration Potential of a 31-year-old Tree-based Intercropping System in Southern Ontario, CanadaAbstract
Carbon (C) storage potential was quantified for four tree species which are commonly incorporated into tree-based intercropping (TBI) systems and compared with conventional agricultural systems in southern Ontario, Canada. In the 31-year-old TBI system at the University of Guelph's Agroforestry Research Station, Norway spruce (Picea abies), white cedar (Thuja occidentalis), black walnut (Juglans nigra) and red oak (Quercus rubra) were planted in tree rows, intercropped with soybean (Glycine max). In the conventiona [...] 1385 7995 |
Some Aspects of Marine Meteorology and Air-Sea-Wetland-River Interactions During Hurricane Ida (2021)by
Abstract
In August 2021 Hurricane Ida devastated southeast Louisiana. On the basis of numerous pertinent meteorological-oceanographic (met-ocean) information including datasets and graphics as supplied by various public agencies, several unique topics related to marine meteorology and air-sea-land interactions are investigated. It is found that a newly proposed revised relation between minimum sea-level pressure and maximum sustained wind speed is verified during Ida. Characteristics of the rapid intensification, defined as [...] 1078 6889 |
Impact of COVID-19 on Chile's Energy Transition Policies and Goalsby
Abstract
Because of climate change, greenhouse gas (GHG) emissions have increased, leading to the implementation of energy transition policies. Countries have adopted the Paris Agreement to curb the effects of climate change. The emergence of COVID-19 in 2020 led to the application of different measures to stop its transmission. This study evaluated the effects of COVID-19-related restrictions (such as quarantine and mobility restriction) in Chile during the first wave on compliance with the country's energy transition poli [...] 1015 6581 |
Biogeochemical Engineering: Technologies for Managing Environmental RisksAbstract
This research aims at one of the most important economic and environmental problems - the elimination of the consequences in case of emergency spills while cleaning petroleum products. The objectives of the study include the development and production of new biological products and biosorbents based on carbon-oxidizing microorganisms, testing the developed technologies for environmental risk management to eliminate the consequences of emergency petroleum product spills, creating an algorithm for conducting prelimin [...] 1067 6723 |
The Role of Agriculture in the Australian Government’s Emission Reduction FundAbstract
Australia’s greenhouse gas emissions from agriculture in 2020 were 67.8 million (M) tonnes (t) of carbon dioxide equivalent (CO2-e), amounting to 12.9% of total emissions. Erupted methane (CH4) from ruminant animals comprised 42% of agricultural emissions. By 2030, the Australian Government aims to reduce total emissions by 43% from the 2005 level. The primary policy instrument for achieving this reduction is the Emissions Reduction Fund (ERF) in which there are two main pathways for agriculture – emiss [...] 1296 7862 |
Implementation of a Dynamic Thermal and Illuminance Control System in Responsive Façades: Shading Studyby
Abstract
This study evaluates three shading configurations designed and tested in a preliminary stage of responsive shading device development. The strategy is based on trigonometric relationships focused on solar angles at any given moment. The configurations are thus related to the ratio of the window area shaded by a responsive brise-soleil that provides 0%, 50%, or 100% shading of the indoor space, based on the daylight needs and the indoor thermal control realized. Shading simulations were performed for Pomona, Califor [...] 1311 8028 |
The Technology of Upward Capillary Formation of Waste for Creating a Deposit before Land ReclamationAbstract
Mineral resources in the subsoil are classified as exhaustible. One of the ways to potentially replenish the sources of mineral resources is presented in the materials of these studies. In this article, we studied the natural formation in the bowels of the array of zones of high concentrations of compounds of useful components. We aimed to develop the technological methods of mass transfer and directed deposition of useful components. The technological transition of mineral resource extraction from the “gathering” [...] 907 6119 |
The Role of Tribal Leaders/Traditional Leaders in Regulating Land Use and Biodiversity Among the Gurune-Speaking People of the Upper East Region in GhanaAbstract
Regulating land use and the biodiversity of a region requires lasting accords between those who make the decisions and those who are affected by the rules and regulations. In Africa, these accords depend on the effectiveness of the collective efforts of the representatives of the legal authorities and the civil society (the traditional leaders in the tribal system). In this study, we investigated the role of tribal leaders in conserving biodiversity (which is a base for obtaining accords with statutory regulations) [...] 1158 12343 |
Outcomes of Ecuador’s Rights of Nature for Nature’s Sakeby
Abstract
The rights of nature have been widely discussed at a philosophical level for a long time, but examples of its practical application are quite rare. Ecuador is the first country to incorporate this concept into its constitutional foundation and put the theory into practice. However, implementing entirely justifiable rights of nature is hindered by factors, such as economic considerations, legal interpretations, cultural norms, political will, and disproportionate perspectives of “the greater good”. After getting opp [...] 1321 16797 |
