Raw material

Raw material is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Raw material rather than just read about it. In short: A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials / intermediate goods that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.

Key takeaways

  • Raw material belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Raw material to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Raw material from memory before moving on to harder problems.

Reference excerpt

A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials / intermediate goods that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products. The term raw material denotes materials in unprocessed or minimally processed states such as raw latex, crude oil, cotton, coal, raw biomass, iron ore, plastic, air, logs, and water. The term secondary raw material denotes waste material which has been recycled and injected back into use as productive material.

Raw materials in supply chains Supply chains typically begin with the acquisition or extraction of raw materials. For example, the European Commission notes that food supply chains commence in the agricultural phase of food production. Bob Heaney reported in 2014 that raw material deliveries in full/on time were among the least-tracked activities within supply chain operations, with only 43% of companies' supply chain senior staff surveyed by the Aberdeen Group reporting that they tracked raw material deliveries, and only 19% having this as an automated process. A 2022 report on changes affecting international trade noted that improving sourcing of raw materials has become one of the main objectives of companies reconfiguring their supply chains. In a 2022 survey conducted by SAP, wherein 400 US-based leaders in logistics and supply chain were interviewed, 44% of respondents cited a lack of raw materials as a reason for their supply chain issues. Forecasting for 2023, 50% of respondents expect a reduced availability of raw materials in the US to drive supply chain disruptions.

Raw materials markets Raw materials markets are affected by consumer behavior, supply chain uncertainty, manufacturing disruptions, and regulations, amongst other factors. This results in volatile raw materials markets that are difficult to optimize and manage. Companies can struggle when faced with raw material volatility due to a lack of understanding of market demands, poor or no visibility into the indirect supply chain, and the time lag of raw materials price changes. Volatility in the raw materials markets can also be driven by natural disasters and geopolitical conflict. The COVID-19 pandemic disrupted the steel industry, and once demand rebounded, prices increased 250% in the U.S. The Russian invasion of Ukraine caused the price of natural gas to increase by 50% in 2022. AI-based forecasting models can analyze historical prices and market variables to estimate raw-material price movements, supporting procurement timing and cost-risk management in industries such as construction and steel.

Raw material processing

Ceramic While pottery originated in many different points around the world, it is certain that it was brought to light mostly through the Neolithic Revolution. That is important because it was a way for the first agrarians to store and carry a surplus of supplies. While most jars and pots were fire-clay ceramics, Neolithic communities also created kilns that were able to fire such materials to remove most of the water to create very stable and hard materials. Without the presence of clay on the riverbanks of the Tigris and Euphrates in the Fertile Crescent, such kilns would have been impossible for people in the region to have produced. Using these kilns, the process of metallurgy was possible once the Bronze and Iron Ages came upon the people that lived there.

Metallic Many raw metallic materials used in industrial purposes must first be processed into a usable state. Metallic ores are first processed through a combination of crushing, roasting, magnetic separation, flotation, and leaching to make them suitable for use in a foundry. Foundries then smelt the ore into usable metal that may be alloyed with other materials to improve certain properties. One metallic raw material that is commonly found across the world is iron, and combined with nickel, this material makes up over 35% of the material in the Earth's inner and outer core. The iron that was initially used as early as 4000 BC was called meteoric iron and was found on the surface of the Earth. This type of iron came from the meteorites that struck the Earth before humans appeared, and was in very limited supply. This type is unlike most of the iron in the Earth, as the iron in the Earth was much deeper than the humans of that time period were able to excavate. The nickel content of the meteoric iron made it not necessary to be heated up, and instead, it was hammered and shaped into tools and weapons.

Iron ore

Iron ore can be found in a multitude of forms and sources. The primary forms of iron ore today are Hematite and Magnetite. While iron ore can be found throughout the world, only the deposits in the order of millions of tonnes are processed for industrial purposes. The top five exporters of Iron ore are Australia, Brazil, South Africa, Canada, and Ukraine. One of the first sources of iron ore is bog iron. Bog iron takes the form of pea-sized nodules that are created under peat bogs at the base of mountains.

Conflicts of raw materials Places with plentiful raw materials and little economic development often show a phenomenon known as "Dutch disease" or the "resource curse", which occurs when the economy of a country is mainly based upon its exports because of its method of governance.

Kolbert summarizes archeologist Colwell's review of the evolution of technology, which has ended up giving the Global North a superabundance of "stuff", at an unsustainable cost to the world's environment and reserves of raw materials.

Worked examples

Example 1 — a first encounter with Raw material

Start with the simplest possible case. Write down what Raw material claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Raw material before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Raw material ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Raw material

In research
Raw material appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Raw material in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Raw material is common in secondary-school and first-year university syllabi. It links to neighbouring topics Materials, Minerals, so understanding it makes those chapters shorter.
In everyday life
Look for Raw material outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
