Valorization of Bread Waste into Value-Added Products
Bread is a universal food that is sold and consumed across the entire social and geographical spectrum. Bread waste is currently of increasing interest, as it is considered a huge global issue with serious environmental impacts and significant economic losses that have become even greater in the post-pandemic years due to an increase in cereal prices, which has led to higher production costs and bread prices. Meanwhile, many efforts have been initiated in the past decades to investigate methods of repurposing bread residues into fuel and chemicals such as bioethanol, biohydrogen, succinic acid, and various added-value products that can be exploited in versatile industries.

Heavy Metals in Agricultural Soils
Population growth and increasing food demand have led to an intensification of agricultural production systems, putting stress on soils and increasing soil contaminants. Some human-induced contaminants, such as heavy metals (HMs), are well-known and have been present in agricultural soils for a long time. In order to provide an overview of HMs in agricultural soils, it is important to investigate agriculturally related sources of contamination with HMs, behaviour of HMs in agricultural soils, as well as their interactions with soil microorganisms, fauna, and plants.

Thermal Treatment Emissions Focusing on CO2 Parameter
Waste-to-energy (WtE) technologies can offer sustainable solutions for waste that cannot be further reused or recycled, such as the part of municipal solid waste (MSW) that is not suitable for recycling processes. The two main (most widely used) thermal treatment technologies that can be applied to MSW are direct combustion in an incineration plant and gasification.

Challenges to Renewable Energy Transition in China
Climate change and energy issues have become the prominent global challenge and a major concern of China. China’s energy sector, which heavily relies on fossil energy, especially coal, is the largest contributor to China’s carbon emissions. According to the International Energy Agency (IEA), China’s energy consumption accounts for nearly 90% of China’s total CO2 emissions in 2020. The carbon neutrality target poses a huge challenge to China’s energy system, causing energy transition to be the key to the overall decarbonization of China’s economy and society.

Environmental Protection and Sustainable Development in Madagascar
Located on the East coast of Africa, Madagascar is the world’s fourth-biggest island; Madagascar is host to 12,000 species of vascular plants (96% endemic). Over 90% of all its wildlife is found nowhere else on earth, and 5% of all of the earth’s biodiversity is found in Madagascar. A place where environmental degradation problems have created severe erosion and water quality problems. Despite its biological and cultural diversity, Madagascar is among the poorest countries in the world, with approximately 78% of the population living in extreme poverty with an average income of less than USD 2 per day, and more than three-quarters of the population in rural areas engaged in natural resources dependent livelihood activities.

Allelopathy of S. canadensis
Solidago canadensis L. is native to North America and have naturalized many other continents including Europa and Asia. Their species is an aggressive colonizer and forms thick monospecific stands. Allelopathy is the chemical interaction between donor plants and recipient plants through allelochemicals. Allelochemicals are produced in some plant parts and released into the vicinity of the donor plants, including their rhizosphere soil either by the root exudation, rainfall leachates, volatilization from the plant parts or decomposition processes of plant residues.

Soil Nanoremediation and Mushrooms
Soil pollution is a serious challenge facing the global community. This pollution is a direct and/or indirect harmful deterioration, which penetrates all aspects of our life, especially human health. Therefore, there is an urgent need to repair, remove, or decompose these pollutants according to various approaches. Concerning the relationship between soil nanoremediation and its mushrooms, this process can be called nano myco-remediation. The mechanism of this kind of remediation depends mainly on the enzymatic system of mushroom species and is involved in the bioremediation of organic environmental pollutants.

Driving Forces behind Climate Change
Climate change occurs through a complex set of interactive driving forces. According to the Intergovernmental Panel on Climate Change sixth assessment report (AR6; https://wg1.ipcc.ch/index.php/ar6/sixth-assessment-report-ar6; Accessed on 5 November 2022), human activity is the main driving force of climate change, whereas others contend that natural factors are also main causes.

Treatment Techniques of Urban Artificial Landscape Water Bodies
Throughout the literature, terminologies such as “urban artificial water bodies”, “landscape water bodies”, “scenic water bodies”, and “landscape water” are all used to refer to any body of water that is created artificially or organically to enhance the aesthetic of towns, cities, and tourist destinations. They are referred to as artificial landscape water bodies (ALWs). ALWs are among the many green strategies adopted to improve the biodiversity, aesthetics, and general environmental health of urban environments. The challenge of pollution control in ALWs has seen the implementation of physical, chemical, and bio-ecological techniques. Generally, chemical techniques have been credited with providing rapid and effective solution to ALWs eutrophication and algae bloom, however their use may result in secondary pollution and harm to the ecological integrity of these water bodies. Physical techniques have also achieved some success in the control and remedy of ALWs.

Carbon Materials as Cathode for Dual-Carbon Lithium-Ion Capacitors
Lithium-ion capacitors (LICs) have drawn increasing attention, due to their appealing potential for bridging the performance gap between lithium-ion batteries and supercapacitors. Especially, dual-carbon lithium-ion capacitors (DC-LICs) are even more attractive because of the low cost, high conductivity, and tunable nanostructure/surface chemistry/composition, as well as excellent chemical/electrochemical stability of carbon materials. Based on the well-matched capacity and rate between the cathode and anode, DC-LICs show superior electrochemical performances over traditional LICs and are considered to be one of the most promising alternatives to the current energy storage devices. The mismatch between the cathode and anode could be further suppressed by applying carbon nanomaterials.
