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 that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.
Biotic material, natural material, or natural product, a material produced by a living organism; Biomass, living or dead biological matter, often plants grown as fuel; Biomass (ecology), the total mass of living matter in a given environment, or of a given species; Body fluid, any liquid originating from inside the bodies of living people
A journal entry is the act of keeping or making records of any transactions either economic or non-economic. Transactions are listed in an accounting journal that shows a company's debit and credit balances. The journal entry can consist of several recordings, each of which is either a debit or a credit.

The term biotechnology was first used by Károly Ereky in 1919 [2] to refer to the production of products from raw materials with the aid of living organisms. The core principle of biotechnology involves harnessing biological systems and organisms, such as bacteria, yeast , and plants, to perform specific tasks or produce valuable substances.
Direct materials cost the cost of direct materials which can be easily identified with the unit of production. For example, the cost of glass is a direct materials cost in light bulb manufacturing. [1] The manufacture of products or goods requires material as the prime element. In general, these materials are divided into two categories.
Material flow accounts provide information on the material inputs into, the changes in material stock within, and the material outputs in the form of exports to other economies or discharges to the environment of an economy. Material flow accounting can be used in national planning, especially for scarce resources, and also allows for forecasting.
In terms of molecular structure, one distinguishes first between low-molecular-weight (LMW) and high-molecular-weight (HMW) products. The generally accepted threshold between LMW and HMW is a molecular weight of about 700 g/mol. LMW fine chemicals, also designated as small molecules, are produced by traditional chemical synthesis, by microorganisms (fermentation or biotransformation), or by ...
Kline matrix. [4]Kline matrix was presented for the first time in 1970 by Charles Howard Kline. [5] It is a more detailed classification of the previous one, that distinguished chemical commodities into two subclasses, called respectively "true commodities" and "pseudocommodities".
