Stone paper is made from stone which is crushed into powder form, mixed with a non-toxic and recyclable binder, i.e. HDPE [7]. Stone paper containing 80% limestone and 20% recycled polyethylene have been produced by a industry in Germany. The mixture of raw materials used are claimed environmentally friendly and can be used for several
The basic difference between stone paper and conventional paper is in terms of the raw materials used. Conventional paper uses plant fibers as raw material and a lot of water in the production process, while stone paper does not use plant fibers and water at all in its production process. In addition, stone paper production produces low

Within this review, the manufacture of stainless steel is considered to include the stages of stainless steel production from melting through to finishing. Stainless steel production gives rise to a mixture of airborne dusts and fumes, and thus presents the potential for inhalation exposure in the occupational setting. The airborne dusts and
Raw steel was produced by 50 companies at 101 minimills. Combined production capacity was about 106 million tons. Indiana accounted for an estimated 27% of total raw steel production, followed by Ohio, 11%; Pennsylvania, 5%; Illinois and Texas, 4% each; and Michigan, 3%; with no other State having more than 3% of total domestic raw steel ...
In general, pulp, which is the raw material of paper, can be manufactured using two methods: chemical pulping or mechanical pulping. The first one involves breaking down the chemical structure of lignin into a liquid using different chemicals, including sodium hydroxide and sodium sulfide. Cooking liquor is a by-product of the production, which ...
The steel industry is facing problems such as serious environmental pollution and high resource consumption. At the same time, it lacks effective methods to quantify potential environmental impacts. The purpose of this work is to conduct a specific environmental analysis of steelmaking production in steel plants. The ultimate goal is to …

Today, the manufacturing of steel is done by using one of these two methods : Blast furnace: The blast furnace process, also known as the basic oxygen process (BOP), combines raw iron ore with small amounts of steel scrap metal into a furnace. Then, pure oxygen is blown into the furnace, raising its temperature.
This paper deals with carbon steel and stainless steel clad-plate properties. Cladding is performed by the submerged-arc welding (SAW) overlay process. Due to element diffusion (Fe, Cr, Ni, and Mn ...

Paper for recycling is mixed with processed water and then stirred in a giant stainless steel vat, called a pulper, to make a fibre suspension. Impurities are removed using a series of screens, to ensure that we only produce high-quality paper that can be used to make high-performance packaging.
Typical mechanized paper production involves two main processes: the treatment of raw material, which includes converting chip into pulp, washing and bleaching, refining, beating, sizing, coloring of the fibers, and later to form paper sheet in a Fourdrinier machine.

70 per cent of all stainless steel is austenitic. It contains at least 16% chromium and 6% nickel. Austenitic stabilisers are elements that are added to prompt the formation of austenite microstructure. This stainless steel grade is a non-magnetic metal and unable to be hardened by heat treatment.
The use of co-products has contributed to a material efficiency rate in the steel industry of 96.3% worldwide (average of all steel industry efficiency rates). Our goal is the efficient use of raw materials and zero waste. Co-products can be used during the steelmaking process or sold for use by other industries.
