Chemicals in the context of "Burn"

Petroleum products are materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. Most petroleum is converted into petroleum products, which include several classes of fuels.

According to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as "energy carriers", i.e. various grades of fuel oil and gasoline. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Since petroleum often contains a few percent sulfur-containing molecules, elemental sulfur is also often produced as a petroleum product. Carbon, in the form of petroleum coke, and hydrogen may also be produced as petroleum products. The hydrogen produced is often used as an intermediate product for other oil refinery processes such as hydrocracking and hydrodesulfurization.

Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It should not be confused with green chemistry, which seeks to reduce potential pollution at its source. It can be defined as the study of the sources, reactions, transport, effects, and fates of chemical species in the air, soil, and water environments; and the effect of human activity and biological activity on these. Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic and soil chemistry, as well as heavily relying on analytical chemistry and being related to environmental and other areas of science.

Environmental chemistry involves first understanding how the uncontaminated environment works, which chemicals in what concentrations are present naturally, and with what effects. Without this it would be impossible to accurately study the effects humans have on the environment through the release of chemicals.

The nation of Spain has a highly developed social market economy. It is the world's 12th largest by nominal GDP and the sixth-largest in Europe (fifth excluding Russia). Spain is a member of the European Union and the eurozone, as well as the Organization for Economic Co-operation and Development and the World Trade Organization. In 2024, Spain ranked as both the 17th-largest exporter and the 17th-largest importer in the world. Furthermore, Spain is listed 28th in the United Nations Human Development Index and 30th in GDP per capita by the International Monetary Fund. Some main areas of economic activity are the automotive industry, medical technology, chemicals, shipbuilding, tourism and the textile industry. Among OECD members, Spain has a highly efficient and strong social security system, which comprises roughly 23% of GDP.

During the Great Recession, Spain's economy was also in a recession. Compared to the EU and US averages, the Spanish economy entered recession later, but stayed there longer. The boom of the 2000s was reversed, leaving over a quarter of Spain's workforce unemployed by 2012. In aggregate, GDP contracted almost 9% during 2009–2013. In 2012, the government officially requested a credit from the European Stability Mechanism to restructure its banking sector in the face of the crisis. The ESM approved assistance and Spain drew €41 billion. The ESM programme for Spain ended with the full repayment of the credit drawn 18 months later.

Bulk material handling is an engineering field that is centered on the design of equipment used for the handling of dry materials. Bulk materials are those dry materials which are powdery, granular or lumpy in nature, and are stored in heaps. Examples of bulk materials are minerals, ores, coal, cereals, woodchips, sand, gravel, clay, cement, ash, salt, chemicals, grain, sugar, flour and stone in loose bulk form. It can also relate to the handling of mixed wastes. Bulk material handling is an essential part of all industries that process bulk ingredients, including: food, beverage, confectionery, pet food, animal feed, tobacco, chemical, agricultural, polymer, plastic, rubber, ceramic, electronics, metals, minerals, paint, paper, textiles and more.

Major characteristics of bulk materials, so far as their handling is concerned, are: lump size, bulk weight (density), moisture content, flowability (particle mobility), angle of repose, abrasiveness and corrosivity, among others.

Sustainable Development Goal 12 (SDG 12 or Global Goal 12), titled "responsible consumption and production", is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording of SDG 12 is "Ensure sustainable consumption and production patterns". SDG 12 is meant to ensure good use of resources, improve energy efficiency and sustainable infrastructure, provide access to basic services, create green and decent jobs, and ensure a better quality of life for all. SDG 12 has 11 targets to be achieved by at least 2030, and progress towards the targets is measured using 13 indicators.

Sustainable Development Goal 12 has 11 targets. The first 8 are outcome targets, which are: implement the 10‑Year Framework of Programs on Sustainable Consumption and Production Patterns; achieve the sustainable management and efficient use of natural resources; reducing by half the per capita global food waste at the retail and consumer levels and the reduction of food losses along production and supply chains, including post-harvest losses; achieving the environmentally sound management of chemicals and all wastes throughout their life cycle; reducing waste generation through prevention, reduction, recycling and reuse; encourage companies to adopt sustainable practices; promote public procurement practices that are sustainable; and ensure that people everywhere have the relevant information and awareness for sustainable development. The three means of implementation targets are: support developing countries to strengthen their scientific and technological capacity; develop and implement tools to monitor sustainable development impacts; and remove market distortions, like fossil fuel subsidies, that encourage wasteful consumption.

Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.

From 1930 to 2014 more than 3200 mutagenic plant varieties were released that have been derived either as direct mutants (70%) or from their progeny (30%). Crop plants account for 75% of released mutagenic species with the remaining 25% ornamentals or decorative plants. However, although the FAO/IAEA reported in 2014 that over 1,000 mutant varieties of major staple crops were being grown worldwide, it is unclear how many of these varieties are currently used in agriculture or horticulture around the world, as these seeds are not always identified or labeled as having a mutagenic provenance.
