Groundwater Remediation Technologies
Groundwater contamination is one of the most concerning issues from uranium mining activities. Radionuclides cannot be destroyed or degraded, unlike some organic contaminants (and similar to metals). Besides, sites, where radionuclides may be found, are mainly radioactive and mixed waste disposal areas, and therefore many other contaminants may also be present in groundwater.

Years of Living Dangerously
Years of Living Dangerously is an American documentary television series focusing on global warming. The first season was broadcast in the US in 2014 on Showtime. It won an Emmy Award as Outstanding Documentary or Nonfiction Series. The second season aired on the National Geographic Channel in 2016. Executive producers included James Cameron, Arnold Schwarzenegger, and series creators Joel Bach and David Gelber (formerly of 60 Minutes). Joseph Romm and Heidi Cullen were the chief science advisors. The weekly episodes featured celebrity hosts with a history of environmental activism and well-known journalists with a background in environmental reportage. These "correspondents" traveled the world and throughout the U.S. to interview experts and ordinary people affected by, and seeking solutions to, the effects of global warming. They acted as reporters and proxies for the audience, asking questions to find out people's opinions and to discover the scientific evidence. The final episode of season one featured an interview of President Barack Obama. Episodes explored the effects of rising sea levels, historic droughts and flooding, water scarcity, ocean acidification, deforestation and the rapidly increasing extinction rate of species, but also focused on "solutions that individuals, communities, companies and even governments can use to address worldwide climate change", including cheaper solar and wind energy, advancing battery technology and electric cars. Hosts included Cameron, Schwarzenegger, Harrison Ford, Ian Somerhalder, America Ferrera, David Letterman, Gisele Bündchen, Jack Black, Matt Damon, Jessica Alba, Sigourney Weaver, and various other actors and journalists. Schwarzenegger reflected on how the series tries to make the issue of climate change resonate with the public: "I think the environmental movement only can be successful if we are simple and clear and make it a human story. We will tell human stories in this project. The scientists would never get the kind of attention that someone in show business gets." Cameron elaborated: "We didn’t use our celebrities as talking head experts, because they’re not climate experts. They were concerned, intelligent, curious citizens who were out to find answers. They were functioning as journalists." Newsweek said that the celebrity hosts "lend sparks to an issue that sends most viewers for the exits".

Plant Growth in Altered Gravity/Microgravity
Understanding how plants respond and adapt to extraterrestrial conditions is essential for space exploration initiatives. Deleterious effects of the space environment on plant development have been reported, such as the unbalance of cell growth and proliferation in the root meristem, or gene expression reprogramming. However, plants are capable of surviving and completing the seed-to-seed life cycle under microgravity. A key research challenge is to identify environmental cues, such as light, which could compensate the negative effects of microgravity.

Green Jobs
Green jobs, described as those jobs generated around sustainability and European Green Deal (EGD), have become “the emblem of this sustainable economy” according to the United Nations Environment Programme (UNEP) report. Studies on green economy and green tourism have increased substantially in the last decade, but it is also true that there is a lack of studies that determine what green job opportunities exist in the Spanish hotel sector under the umbrella of Sustainable Development Goals (SDGs) and sustainability policies.

Olive Oil Wastewater Management
Olive oil production processes usually generate large amounts of high load polluted wastewater known as Olive Mill Wastewater (OMW), locally known as “Zibar”. Most of these olive oil-producing processes are found in the Mediterranean countries, where olive trees are planted to produce both olives and olive oil.

Macrophytes in Constructed wetlands
The vegetation in constructed wetlands (CWs) plays an important role in wastewater treatment. Popularly, the common emergent plants in CWs have been vegetation of natural wetlands. However, there are ornamental flowering plants that have some physiological characteristics similar to the plants of natural wetlands that can stimulate the removal of pollutants in wastewater treatments.

BIM, GPP for CDW Management
Information Modelling and Management (IMM) methods for Most Economically Advantageous Tender (MEAT) can promote the adoption of environmentally sustainable practices. Despite the wide regulatory framework and existing drivers, Construction and Demolition Waste (CDW) trend is still upward. The literature review regarding IMM and CDW management implementation during the design phases is mainly focused on studies and applications from the designer and contractor’s points of view, although few studies focused on Green Public Procurement (GPP) and CDW management integration from the Public Client’s point of view. This research aims at investigating the integration and efficiency of MEAT and IMM to promote the application of sustainable strategies focused on waste reduction and resource valorization. The study investigates the Public Client’s role in promoting sustainable practices, introducing digital material inventory and BIM during the design phases, and including environmental award criteria in the call for tender documents. A Design Build (DB) procurement model is considered in the case study of a brownfield renovation and the construction of a new school in northern Italy. The methodology provided the Public Client with a replicable method to evaluate the environmental impact of the bids, allowing for proper selective demolition planning, CDW decrease, and organization while promoting their integration in companies’ expertise and procedures.

Environmental Management Strategies in Mining Industry in Chile
Sustainable development in the mining industry is a critical concern for companies because it covers multiple environmental, social, and economic approaches. The principal aim of sustainable development is to find the equilibrium between environmental, social, and economic aspects to maintain the system’s stability. In this sense, defining mining sustainability is a complex task because of the multidimensional definition of sustainability. However, the primary concern of the environmental sustainability of the mining industry is to avoid and reduce environmental impact at different stages of the mining life cycle, where the mining industry needs to anticipate possible negative effects that its operations may generate. The mining industry faces diverse challenges to maintain sustainable production, particularly regarding critical water and energy supplies. As a significant player in the copper mining industry, Chile has become a global reference. The most prevailing strategies involved implementing Environmental Management Systems, which allow organisations to define, implement, and track their specific goals and standards.

List of Minerals I (Complete)
This list includes those recognised minerals beginning with the letter I. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). The list is divided into groups: The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'. The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).
