Consumable

Consumables are materials that become part of goods , goods and works .

According to this system, commodities are substances that are necessary for the production process but do not become part of the good, the goods or the work.

In construction , the consumables are called building materials . One example is “lost formwork”: after pouring, the formwork boards are left in place at certain points - it would be significantly more expensive to dismantle, clean and temporarily store them than to buy new formwork boards the next time they are needed.

Operating materials and auxiliary materials are largely regarded as synonymous.
