India becomes 3rd largest steel producer in the world during 2015. But per capita consumption of steel in India continues to be as low as 60.6 kg only, against that of world average of around 208.6 kg. There are potential for growth and vast domestic demand. It is likely to increase 95 kg by 2020 and 150 kg by 2030. India's goal is 300 million tonnes (Mt) steel …
Binders, such as bentonite, clay, hydrated lime or an organic binder, are generally used to raise the wet strength of green balls to more acceptable levels for handling. Bentonite consumption at the rate of 6.3–10 kg per ton of feed is a significant cost element and adds to the silica content of the final product.
typical binder is bentonite or organic binder. Adding lime and/or dolomite to the ore adjusts the pellets so as to have the target chemical composition3). 1.3 Balling process In this process, balling equipment produces green balls from the pre-wetted material prepared in the previous process. The green balls are produced either
Conventional pellets using bentonite as the binder need to be indurated at ~1300 °C to achieve a compression strength of ~2.3 kN. But bentonite add to the slag burden and increase energy and fuel consumption. Organic binders like carboxymethyl cellulose (CMC), starch and dextrin are burnt out at low temperatures (< 250 °C).
Semi-coke powder is generally an industrial by-product, made from low-rank coal by a low-temperature coal carbonization process (500 °C–700 °C) in …
Pyrogenic carbon (PyC; includes soot, char, black carbon, and biochar) is produced by the incomplete combustion of organic matter accompanying biomass burning and fossil fuel consumption. PyC is pervasive in the environment, distributed throughout the atmosphere as well as soils, sediments, and water in both the marine and terrestrial environment. The …

Hence organic binders were developed. Use of pellets increases the productivity in blast furnace and reduces coke consumption. By using pre-reduced pellets an increase in production of at least 25 to 30% can be obtained in the existing blast furnace. ... a decrease in the porosity with increasing binder percentage.
Organic binders are more promising than inorganic binders, because they increase the heating value of biomass pellets and reduce the introduction or emission of metal elements. Starch is a cheap and available natural binder, the bonding mechanism of which is mainly attributable to gelatinization.
During the coke quenching, handling, and screening operation, coke breeze is produced. It is either reused on site (e.g., in the sinter plant) or sold off site as a by-product. Waste Characteristics The coke oven is a major source of fugitive air emissions. The coking process emits particulate matter (PM); volatile organic compounds

A small decrease in arsenic (As) level was also detected in the organic fertilizer treatment group, but the difference was not statistically significant. Similar trends were observed in non-rhizosphere soil samples. Our results also showed that treatment with organic fertilizer significantly decreased contents of Cd, Pb and As in tea leaves ...

The global no/low alcohol market is projected to continue growing as consumers seek to reduce their alcohol consumption. "What we're seeing is a moderation trend that's sweeping across key global markets, and that's bringing with it increased demand for reduced alcohol, or alcohol-free drinks," says IWSR.
