1. Introduction. The growth of e-waste streams brought by accelerated consumption trends and shortened device lifespans is poised to become a global-scale environmental issue at a short-term [1], i.e., the electromotive vehicle industry with its projected 6 million sales for 2020 [[2], [66]].Efforts for the regulation and proper …
Small WWTPs, that have an impact on the sensitive headwater community, can be relieved by transferring wastewater to the next larger plant (Harth et al., 2018). Our study, along with others ( Büttner et al., 2022 ), found that headwater sections are heavily impacted by WWTPs, resulting in altered invertebrates communities and subsequently …
Solar energy is a rapidly growing market, which should be good news for the environment. Unfortunately there's a catch. The replacement rate of solar panels is faster than expected and given the ...
Freshwater ecosystems such as lakes and rivers are among the sensitive ecosystems, which host rich biodiversity. Being major freshwater resources, they provide a wide range of ecosystem services, making their existence essential for the well-being of human societies. However, in the past few decades, there have been adverse impacts …
Wastewater treatment plants (WWTPs) play a critical role in the sustainable development of water resources due to its outstanding ability of removing pollutants from complex influent wastewater and generating clean and safe effluent. This paper innovatively adopted the meta-analysis method in view of published LCA studies to …
Uncollected waste and poorly disposed waste have significant health and environmental impacts. The cost of addressing these impacts is many times higher …
Wastewater is a major threat to nature and human health. Without adequate treatment, wastewater can contribute to habitat loss and extinction. TNC is actively addressing …
Upgrades of wastewater treatment plant (WWTP) and full-scale application of additional advanced oxidation processes have been proven to be effective in reducing the nutrient emissions to the environment; however, the impacts of WWTP upgrades on the receiving waters with regard to the occurrence and ecological risks of pharmaceuticals …
Treated effluent from municipal wastewater treatment plants (WWTPs) is a major source of contamination that can impact population size, community structure, and biodiversity of aquatic organisms. However, because the majority of field research occurs during warmer periods of the year, the impacts of …
Waste-to-energy (WtE) processes, or the combustion of refuse-derived fuel (RDF) for energy generation, has the potential to reduce landfill volume while …
This study aims to understand the influence of wastewater treatment plant discharge on the microplastic status in the surface seawater of Istanbul. For this purpose, for the first time, the distribution, composition, and ecological risk of microplastics at nine sampling stations on the southern coast of Istanbul, Marmara, were investigated at ...
This systematic review aims to identify the health effects on human populations living near waste incinerators to inform the public and guide policymakers, and to define appropriate criteria for approving …
According to CAP (2013), the communities where waste incineration plants are built are at a higher risk for long-term negative health effects such as cancer, birth defects, reproductive dysfunction, neurological problems, and other health effects that are known to occur at very low exposures to many of the metals, and pollutants released by ...
But, a very little consideration is given to effects of components of wastewater on plants, animals, environment and human health. There is the requirement of proper standards and guidelines to limit the reuse of specific types industry treated water. The toxicity and hazardous level should be assessed and analyzed before use in …
Life Cycle Impacts. Wastewater treatment systems reduce environmental impacts in the receiving water, but create other life cycle impacts, mainly through energy consumption. ... Pumping systems, typically consuming 10-15% of energy at wastewater treatment plants, can lead to inefficient energy consumption when pumps, ...
The aim of the present study was therefore to compare the impact of wastewater treatment plant effluent on benthic macroinvertebrate communities between summer and winter. To do this, we examined the impacts of wastewater effluent on benthic macroinvertebrate communities near a large and small WWTP during summer …
Wastewater effluents are major contributors to a variety of water pollution problems. Most cities of developing countries generate on the average 30–70 mm3 of wastewater per person per year. Owing to lack of or improper wastewater treatment facilities, wastewater and its effluents are often discharged into surface water sources, …
Climate change is considered to be one of the main challenges to urban wastewater systems in future decades. It is estimated that climate change has a dual effect on wastewater treatment (WWT) plants. The processes occurring in a wastewater treatment plant (WWTP) are subsequently affected by climate change; more extreme weather …
Human health is being deeply impacted by this lack of environmental accountability and awareness. Over 1,000 chemicalsused in the manufacturing of millions of different plastic products on the market today are classified as endocrine-disrupting and carcinogenic. They have been …
Wastewater treatment plants (WWTPs) are under increasing pressure to enhance resource efficiency and reduce emissions into water bodies. ... Bailey et al. investigated the effects of water conservation on wastewater flow and composition in a sewer network. The stochastic appliance-specific approach based on Blokker (2010) is …
Environmental Impacts of U.S. Food Waste: What resources go into a year of food loss and waste in the U.S.? *excluding impacts of waste management, such as landfill methane emissions. ... Impacts include: greenhouse gas emissions of more than 42 coal-fired power plants; enough water and energy to supply more than 50 million …
Studies had to focus on the impacts of waste incineration on health risk and/or health outcomes. Papers had to be in English and accessible online and could not be protocols. ... Most were cross …
Environ.Res.Lett.15(2020)123006 TCole-Hunteretal 71 WtE plants generating approximately 14 billion KWh of electricity from 30 million tonnes of RDF
