“…Besides ethanol other value-added chemicals can be produced from renewable feedstocks [25]. Simultaneouly efficient processes were developed for the conversion of bagasse to methane [26] or hydrogen [27][28][29][30], or C 5 and C 6 sugars [31,32]. A new innovation showed that sweet sorgum fiber could be used to reinforce fly ash-based geopolymer [33] which is the latest potential use.…”

The development of sweet sorghum syrup producing technology for the juice of cultivar Sucrosorgho 506 was completed. The applicability of different existing syrup production technologies including sugar beet-based sugar production technology, and sugar cane processing technology was also tested. The new chemical-free syrup production technology was realized at laboratory-scale and large laboratory-scale. The proposed technology offers a chemical free separation and concentration of carbohydrates, and consists of centrifugal separation; ultrafiltration extended with an approved sterilization followed by nanofiltration to separate carbohydrates and inorganics, and finally a vacuum evaporation to reach syrup state. By using this technology the initial glucose:fructose:sucrose ratio could be preserved in the syrup, therefore not limiting its further use. The possible food application was established by sensory analysis. It was revealed that the syrup produced via the developed process obtained the most attractive character that enables the opportunity to use as natural sweetener.

“…According to the literature, the optimum pH range for lactose (or whey) acidogenesis is between 6 and 6.5 (Venetsaneas et al 2009). Antonopoulou et al (2008) reported, that high concentration of hydrogen (over 25% v/v) in the gas phase was when the pH in the reactor was maintained at 5.2 ± 0.1. Wang et al (2006) stated, that pH of 5.5 should be avoided in the biohydrogen fermentation process because at that level of pH, the propionic-acid type fermentation commonly occurred.…”

Methane is the main component of the basic conventional fuels used in modern energetics -natural gas, as well as an essential component of renewable fuel like biogas. As a result of technological processes, methane can be extracted from hydrogen fuel which is dedicated to low-temperature fuel cells, generators or electric current and heat. The article reviews the possibilities of using methane to produce electricity, practical solutions and the problems that inhibit the implementation of fuel cell technology.
