Manmade or natural catastrophes cause disruptions of the entire demandsupply chain. Generally, it takes longer to make up the demandsupply chain and ultimately there is a loss of revenue and reputation. The major purpose of this paper is to evaluate the costbenefit and reliability of a biocoal manufacturing plant with deviation in demand. Whenever demand deviates, it affects the ...
1. Introduction Global warming is reduced by the development of clean technology for future security such as bio coal. Biomass is considered greenhouse gas neutral.

Biocoal is ecofriendly, renewable energy fuel, economical cheaper contain high density. Government is providing tax benefit and incentives. It has easy mobility and transportation. Biocoal is solid fuel. The process of converting biomass to solid fuel is also nonpolluting. No addition of any binder/ chemical is required so it is natural.
This process is an alternate strategy for converting the waste biomass into valueadded products like biochar, syngas and biooil. During the process, the lignocellulosic components like cellulose, hemicellulose and lignin undergo reaction processes like depolymerization, fragmentation and crosslinking at specific temperatures resulting in a ...
