The coal cake density plays an a very important role for the coke strength and mechanical strength. There  are  possibilities  to influence these parameters in industrial conditions with mechanical treatment ( parzial briquetting or stamping).
It must be also considered that the stamp technology find a renewed interest both in Asia then in  Europe.

The coking plants production processes involves production of products as  coke, coke-oven gas, tar, benzol, ammonium sulphate, sulphuric acidand/or sulphur.
Unintended result of coking plant production process are non-products, in the past treated as a waste and disposed of by landfilling: nowadays, non-products after proper preparation are used as raw materials for preparation of coal charge and for production of carbon derivatives.

Coking plants do not generate process waste material and  the environmental requirements for the  waste management are satisfied in coking plant process.

The petroleum coke, used as  an additive in coal blends to produce metallurgical coke of acceptable quality, has been tested at JSW.

 

The ability of petroleum coke to interact with coal during plastic stage to impart good
bonding between components and maintain the coke quality  required by  the Blast Furnace,
is well established through laboratory studies.
 
The performance of coke produced from coking coal blends containing petroleum coke was successfully tested in Blast furnaces.
