Water Reuse
Wastewater treatment and reuse has passed through different development stages with time. Based on archeological evidence and time records, the awareness of the Greeks regarding land disposal, irrigation, and water reuse is highlighted. The latter has evolved into a plethora of applications, with Direct Potable Reuse (DPR) representing one of the last modern frontiers.

Mesoporous Materials for Metal-Laden Wastewater Treatment
Rapid technological, industrial and agricultural development has resulted in the release of large volumes of pollutants, including metal ions, into the environment. Heavy metals have become of great concern due to their toxicity, persistence, and adverse effects caused to the environment and population. In this regard, municipal and industrial effluents should be thoroughly treated before being discharged into natural water or used for irrigation. The physical, chemical, and biological techniques applied for wastewater treatment adsorption have a special place in enabling effective pollutant removal.

Impacts of Biowaste with Mitigation Efforts in Cities
In many cities, huge quantities of biowaste solid matterials are generated, making it a big challenge to keep our cities smart/clean without creating health issues. The second challenge is to mitigate solid biowastes from municipalities, and it needs systematic valorization/conversion approaches to transform/generate them into clean/least carbon-emitting fuel sources. This effort can help make smart cities with additional amounts of energy generation that can be used by each citizen for their daily energy needs. In the cities, biowastes are reported as food waste (from domestic kitchens and restaurant/hotel), green plant residues (from parks and other cleaning activities), and other miscellaneous sources.

Brush Management Using Fire in Grassland National Parks
The grasslands of North America are threatened by woody encroachment. Restoring historical fire regimes has been used to manage brush encroachment. However, fire management may be insufficient due to the nonlinear and hysteretic responses of vegetation recovery following encroachment and the social–political constraints affecting fire management.

Mobile Maps Using Eye Tracking
The use of mobile mapping applications is currently one of the most popular methods of navigating in urban spaces. Widespread access to smartphones and a wide range of mobile navigation applications allow each of us quick and easy access to geographic information. Mobile maps, like paper ones, allow the user to browse, search for points of interest and calculate routes, but their significant advantage, as indicated by users, is real-time information about the user’s current position.

Paludiculture in Latvia
Global climate change impact has increased in recent decades and put urgency on implementing effective climate change mitigation (CCM) activities. Rewetting of drained peatlands is an acknowledged measure to reduce GHG emissions from organic soils in the agriculture and land use sectors. Under waterlogged conditions, decomposition of organic matter in peat decreases, and emissions of CO2 are reduced. Thus, the soil carbon stock is saved, and wet management of the site reactivates carbon sequestration. To reach CCM targets, the first rewetting and paludiculture trials have been implemented in Latvia.

The Construction of Seaports in the Arctic
The Arctic zone of the Russian Federation is of strategic importance for the country. Considering the fragility of Arctic ecosystems, special attention needs to be paid to the sustainable development of transport and related infrastructure within the framework of the “blue economy” concept, which is relevant for Arctic waters. At the same time, it is necessary to identify the main factors and tasks of creating transport and port infrastructure, building a modern fleet, and organizing fisheries and tourism in an environmentally sound manner.

Respirable Coal Mine Dust Lung Deposition
Respirable Coal Mine Dust (RCMD), with a specific focus on examining particle deposition across different regions of the airway system and lungs. The interplay of several critical factors, including particle characteristics and an individual’s breathing patterns, plays a pivotal role in determining whether particles settle in the lungs or are exhaled.

Vine and Wine Sustainability in a Cooperative Ecosystem
The world is changing, and climate change has become a serious issue. Organizations, governments, companies, and consumers are becoming more conscious of this impact and are combining their forces to minimize it. Cooperatives have a business model that differs from those in the private or public sector. They operate according to their own principles of cooperation, which makes it difficult to obtain results that are in harmony with the objectives of the organization and the cooperative members.
