Hydroponic Cultivation
The increasing demand for food, the lack of natural resources and arable land, and the recent restrictions on energy consumption require an immediate solution in terms of agricultural activities. The soil loss, the crop/soil contamination, and the greenhouse gas emissions were the criteria for the environmental comparison of conventional agriculture and hydroponics. As for resource consumption, the water consumption rates (L/kg), energy consumption rates (kWh), and energy required (kW) were the criteria for comparing conventional agriculture with hydroponics.

Importance of Greenery in Hot Areas
Global warming and climate change are critical issues that raise attention on a global level. Worldwide, some cities are warming twice as fast as the surrounding rural areas. Greenery is one of the most influential factors in reducing the outdoor air temperature and enhancing the microclimate in hot areas.

Packaging Based on Design for Life Cycle
Though solutions are needed across all sectors, a material considered to have one of the highest potentials and needs for improvement is plastic. The problems resulting from incorrect handling of plastic waste have been identified to be threatening the environment in a variety of ways. Insufficient collection and waste treatment following the disposal lead to leakage directly into the environment, incineration, or landfilling of the ubiquitous material. The topic of plastic pollution and other end-of-life issues have also been picked up by the public since many products made from this material are used by private households. An example in this context is plastic packaging. With packaging having the largest share amongst plastic production and it being a fast-rotating consumer good, a societal focus has been set on plastic packaging as an environmental threat. Despite the immense benefits of plastic packaging to society, the accumulation and treatment of end-of-life plastics are creating a global environmental challenge. To reduce plastic debris in the environment, for example, in the oceans, it has become clear that a focus on design for life and end-of-life is a priority. This concept, also called Design for Life Cycle (DfLC), has been identified to play a major role in minimizing environmental impacts of all kinds of consumer products.

Integrated Design Process for Building Climate Responsiveness
Increasingly prominent energy and environmental problems have pushed for higher requirements for buildings’ energy saving. According to the conventional energy-saving design method, the cooperative operation between architects, structural and equipment engineers and other professionals cannot run smoothly, so the energy-saving and emission reduction efficiency of the whole building cannot be improved effectively. The integrated design process (IDP) is a systematic method, which is applied in the scheme design stage and according to which the multi-level design factors of cities and buildings are considered comprehensively. It provides a concrete path of multi-specialty collaborative operation for the building’s climate responsive design.

Isolation of Bioactive Molecules from Waste Streams
Waste is a heterogeneous and complex matrix, the selective isolation of, for example, polyphenolic compounds, is challenging due to its energy efficiency and at least partially its selectivity. Extraction is handled as an emerging technology in biorefinery approaches. Conventional solid liquid extraction with organic solvents is hazardous and environmentally unfriendly. New extraction methods and green solvents open a wider scope of applications.

Enhancement of Anaerobic Digestion with Nanomaterials
The number of research reporting the addition of nanomaterials to enhance the process of anaerobic digestion has exponentially increased. The benefits of this addition can be observed from different aspects: an increase in biogas production, enrichment of methane in biogas, elimination of foaming problems, a more stable and robust operation, absence of inhibition problems, etc. Several hypotheses have been formulated, with the effect on the redox potential caused by nanoparticles probably being the most accepted, although supplementation with trace materials coming from nanomaterials and the changes in microbial populations have been also highlighted. The types of nanomaterials tested for the improvement of anaerobic digestion is very diverse, although metallic and, especially, iron-based nanoparticles, are the most frequently used.

Underground Plastic Recharge Chambers in Stormwater Management
Land development typically requires stormwater control measures (SCMs) to limit runoff volume, reduce peak flow, delay discharge to streams, and reduce pollutant loads to receiving waters, with the ideal goal of mimicking the natural hydrologic system. Life cycle assessment is used to systematically evaluate the environmental impact of underground plastic recharge chambers (RCs) used for stormwater management. Using cradle-to-gate life cycle assessment and a functional unit of 1 m3 stormwater capacity, different RC structure types, manufacturing processes and materials are considered. The inventory is based on various commercially available RCs, including injection-molded or extruded polypropylene and polyvinylchloride polymers and typical installation materials and methods. A new dataset is developed to estimate the manufacture and use of recycled polypropylene granulate. TRACI 2.1 is used to investigate the midpoint life cycle impact assessment metrics, acidification, eutrophication, global warming, and fossil fuel resources.

Wetland-Microbial Fuel Cell Systems
Water, energy, and food are indispensable for sustainable economic development. Despite nutrients, especially phosphorus and nitrogen, being essential for plant growth and thus food supplies, those present in wastewater are considered an environmental burden. While microbial fuel cells (MFCs) are receiving much interest, combining wastewater treatment with an MFC has emerged as an option for low-cost wastewater treatment. Among others, a constructed wetland (CW) coupled with an MFC (CW-MFC) has the potential to provide a low carbon footprint and low-energy wastewater treatment, as well as nutrient and energy recovery from wastewater. The organic and nutrient removal and power generation by the integrated CW-MFC systems are affected by a number of factors including the organic loading rate, hydraulic retention time, system design, plant species, dissolved oxygen, substrate/media type, influent feeding mode, electrode materials and spacing, and external resistance.

Recent Advances of Perovskite Solar Cells
Perovskite solar cells (PSC) have been identified as a game-changer in the world of photovoltaics. This is owing to their rapid development in performance efficiency, increasing from 3.5% to 25.8% in a decade. Further advantages of PSCs include low fabrication costs and high tunability compared to conventional silicon-based solar cells.
