“…It is worth noting that, the physicochemical treatments could convert the macromolecules in food waste into utilizable forms when performing co‐digestion of food waste and sludge, but various inhibitory products (such as furfural) could also be produced. According to our previous researches, enzymatic hydrolysis could be a promising pretreatment, which could release the nutrients (glucose and free amino nitrogen) from food waste. Therefore, the Aspergillus awamori and Aspergillus oryzae could be used to hydrolyze the food waste to get the glucose and free amino nitrogen‐rich hydrolysate for hydrogen production.…”

Summary The amount of sewage sludge has increased remarkably with the acceleration of urbanization and the promotion of municipal wastewater treatment. Hydrogen is a promising clean fuel, considering the emerging global energy crisis and the growing demand for environmental protection. Producing hydrogen from sewage sludge through anaerobic fermentation is an economical and environmentally sustainable technology. Therefore, in this work, the mechanism of hydrogen production from sludge is critically reviewed and clarified. Current researches including sludge pretreatment and key factors affecting hydrogen production were investigated as well. Some challenges still remain, such as almost all studies feature experiments in batch cultures, and the hydrogen yields were not large. Further studies are needed in this arena, such as inhibiting hydrogen‐consuming bacteria, culturing, and screening high‐efficiency bacteria. The mechanism of hydrogen production from anaerobic co‐digestion, their factors, and techno‐economic evaluation need be further studied as well.

“…For example, every year, nearly 1.3 billion ton of food waste is produced, which accounts for 40% of the total municipal solid waste. For this reason, novel bioprocess for biofuels production from food waste which could not only solve the problem of food waste pollution, but also produce the sustainable and clean energy are developed . However, landfilling, incineration and composting are still three basic technologies for municipal solid waste disposal.…”

In this study four incineration residues (bottom ash), classified as hazardous wastes on the basis of a leaching test, have been investigated. Analysis of the chemical composition proved to have high contents of heavy metals that during storage could potentially be released into the environment. Therefore, the waste has been subjected to solidification/stabilization (i.e., one of the methods of immobilization of heavy metals) in two ways: with Portland cement and alkali‐activated granulated blast furnace slag. It was assumed that bottom ashes will constitute 30% by weight of the dry ingredients. It has been found that although the amount of heavy metals introduced into a matrix along with the mineral waste is significant, the increase in elution of heavy metal ions in the environment is not a consequence. The use of bottom ash from the incineration of hazardous waste may even limit the release of heavy metal ions from cementitious materials. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1074–1082, 2017
