| dredged material Unconsolidated material removed from rivers, streams, and shallow seas with machines such as the bucket-ladder dredge, dragline dredge, or suction dredge | مخلفات تطهير المجاري المائية |
| electronic material No definition needed | مادة إلكترونية |
| energy source material Sources from which energy can be obtained to provide heat, light, and power. Energy resources, including fossil and nuclear fuels as well as solar, water, tidal and geothermal energy, may be captured or recovered and converted into other energy forms for a variety of household, commercial, transportation, and industrial applications | مادة مصدر للطاقة |
| filling material Any substance used to fill the holes and irregularities in planed or sanded surfaces so as to decrease the porosity of the surface for finish coatings | مادة الحشو |
| hazardous working material A poison, corrosive agent, flammable substance, explosive, radioactive chemical, or any other material which can endanger human health or well-being if handled improperly | مادة خطرة في التعامل معها |
| industrial material No definition needed | مادة صناعية |
| insulating material Material that prevents or reduces the transmission of electricity, heat, or sound to or from a body, device or region | مادة عازلة |
| liner material A layer of synthetic or natural materials, on the sides of or beneath a landfill, landfill cell or surface impoundment, that restricts the downward or lateral escape of liquids carrying leachate into the surrounding environment | مادة مبطنة |
| local building material | مواد بناء محلية |
| material life cycle All the stages involved in the manufacturing, distribution and retail, use and re-use and maintenance, recycling and waste management of materials | دورة حياة المادة |
| natural material No definition needed | مادة طبيعية |
| new material Novel high-performance materials obtained through the interdisciplinary research of chemistry, applied chemistry, chemical engineering, and mechanical engineering | مادة جديدة |
| oxidizable material Substance that can undergo a chemical reaction with oxygen | مادة قابلة للأكسدة |
| putrescent material | مادة عفنة أو متعفنة |
| raw material A crude, unprocessed or partially processed material used as feedstock for a processing operation | مادة خام |
| raw material consumption The developed countries depend on a stable supply of raw materials for their industries. Total resource requirements are increasing rapidly over the entire world. In developed countries, although population is increasing slowly, per capita use is increasing rapidly, while the opposite is happening in developing countries. Traditionally raw materials have been classified as non-renewable resources, but a distinction may be important between "loosable" resources, such as oil and coal, and "non-loosable" resources, such as metals, which can be used several times over by recycling processes | استهلاك المواد الخام |
| raw material securing Measures used to ensure the provision of or the access to crude, unprocessed or partially processed materials used as feedstock for processing or manufacturing | تأمين المواد الخام |
| recycled material Waste materials that are transformed into new products in such a manner that the original products may lose their identity | مادة معاد تدويرها |
| renewable raw material Resources that have a natural rate of availability and yield a continual flow of services which may be consumed in any time period without endangering future consumption possibilities as long as current use does not exceed net renewal during the period under consideration | مادة أولية متجددة |
| road construction material The aggregation of components used for building streets, highways and other routes, such as asphalt, concrete, brick, sand and gravel | مواد بناء الطرق |
| scrap material Recyclable material from any manufacturing process or discarded consumer products | المهملات |
| scrap material market The trade or traffic in discarded or leftover materials that can be reused in some way | سوق المهملات |
| scrap material price The amount of money or the monetary rate at which materials discarded from manufacturing operations can be bought or sold | سعر المهملات |
| sound insulation material Material used to reduce the transmission of sound to or from a body, device, room, etc. | مادة عازلة للصوت |
| synthetic material Material made artificially by chemical reaction | مواد مركبة |
| teaching material An article or device used to facilitate the learning process in an instructional setting | مواد تعليمية |
| trace material 1. Both metals and non-metals, essential for the metabolic processes of algae, invertebrates and vertebrates. Organisms that derive nearly all their energy via photosynthesis are especially dependent upon dissolved trace substances. 2. Impurities that are present at small but detectable levels | آثار بقايا مادة |
| trickle of radioactive material | نضيض أو تسرب المادة المشعة |
| use of waste as material | استخدام المخلفات كمواد |
