Raw material is a material intended for further processing in production. In fact, it is with him that the release of any product begins. It is difficult to overestimate the role of the source material, since the quality of the product depends on it. Today there are a huge number of different groups, subgroups and types of raw materials. Let's try to understand this diversity.
What are raw materials for production
Collected or mined materials are usually processed to give them the necessary commercial qualities. Then they either go on sale or continue to participate in subsequent production cycles until they reach the stage of the final product.
Types of raw materials
Classification of raw materials is a very conditional concept. It is customary to distinguish two main groups: industrial and agricultural. The industrial sector includes minerals and energy resources. Agricultural raw materials are cereals, dairy products, meat, medicinal plants. All types of raw materials can be divided into two more groups: it can be primary (directly mined or collected) and secondary (in the form of a by-product or production waste). The secondary group of materials is widely used in industry,which can significantly reduce costs. By origin, all types of raw materials can be divided into 4 subgroups:
- Plant origin (cereals, fruits and vegetables, herbs).
- Animal origin (dairy products, animal excrement).
- Mineral origin (natural gas, coal).
- Biosphere (water and air).
Use of raw materials in production
Today there are a huge number of industries. The list of traditional industries is replenished daily with new names, which means that new raw materials are being developed and used. This is due both to growing global demand and to developing technologies. The most relevant direction today is the development of energy carriers. If a hundred years ago a person was able to obtain energy from oil and coal, today other sources are being actively developed, for example, natural gas. There is an alternative technology for generating electricity, based on natural fermentation processes, when cow dung acts as an energy carrier. But such production as the production of cotton fabric has practically not changed over many centuries. The process itself has been improved and mechanized, but the raw materials are cotton bolls - just as it was 3-4 centuries ago. And the food industry is constantly changing. The desire of the manufacturer to reduce costs turns into a search for new types of the original product. Natural raw materials are the best option. However, unfortunately, in order to save money, it is oftenreplaced by an artificial one. Thus, today one can observe a situation in which some manufacturing industries continue to use any raw materials for centuries, while others develop technologies and develop new types of raw materials.

Absolute alcohol. Industrial production of alcohol from biological raw materials
Absolute ethyl alcohol has found its application in industry. This substance is necessary to ensure the reaction of organic synthesis. Such a liquid is now often used in laboratories. For the first time, the technical specifications dedicated to this substance were published in the 37th year. Currently, there are specialized GOSTs and standards that regulate the quality of the liquid and the nuances of its preparation
Kvass production: necessary equipment, raw materials and recipes
Features of the production and marketing of live kvass. Home or industrial production. The choice of premises and basic equipment, depending on the expected scale of the production of the drink. Technological process of production at the plant. Examples of recipes for home or small production
Materials released to production (posting). Accounting for the disposal of materials. accounting entries
Most of all existing enterprises can not do without inventories used to produce products, provide services or perform work. Since inventories are the most liquid assets of the enterprise, their correct accounting is extremely important
Production of polyurethane foam: technology, raw materials, equipment
Mounting foam from the usual means of sealing window openings has long passed into the status of a full-fledged building material, which is widely used in a variety of types of work. The variety of applications of this product also determines the need for a differentiated approach to the technologies of its manufacture. However, the differences in foam production methods are more of a cosmetic nature, without affecting the basic technological processes
PVC pipe production: technology, raw materials and equipment
Tubular products based on polyvinyl chloride (PVC) are widely used today in a variety of areas and industries from the private sector to large oil and gas enterprises. But the process of their consolidation on the market was gradual, since the physical and technical properties of the polymer material are inferior to traditional metal counterparts in a number of criteria. However, the modern production of PVC pipes, due to the introduction of advanced technologies, has significantly increased the performance of products
