Cementation of Bioproducts Generated from Biodegradation of Radioactive Cellulosic-Based Waste Simulates by Mushroom

Abstract

The current work was devoted to study the solidification of bioproducts originated from the bioremediation of mixture of solid cellulose-based radioactive waste simulates using a mushroom (Pleurotus pulmonarius), in Portland cement. The obtained solidified waste form was subjected to mechanical integrity qualification after curing periods of 28 and 90 days. Chemical performance of the cement-waste form was also evaluated in different leachant media during 540 days. The results obtained gave useful information about the mechanical, physical, and chemical performances of the final cement-waste form incorporated the radioactive bioproducts. Moreover, it indicated that cement can provide a highly durable form that ensures a long-term stability of the solidified waste material and can act as a first barrier against the release of radiocontaminants from radioactive wastes to the surrounding environment.

Unveiling the Nutritional, Therapeutic, and Environmental Impact of Oyster Mushrooms (Pleurotus species): A Review

“…Pleurotus pulmonarius is identified as an effective fungus in degrading crude oil, offering a natural solution to oil spill remediation efforts [65]. Moreover, the efficacy of Pleurotus pulmonarius is successfully confirmed in combating radioactive cellulosebased waste, signifying its worth in nuclear waste management [66]. Spent Mushroom Compost (SMC) has arisen as a treasured resource in myco-remediation, with studies by Law et al revealing the capacity of Pleurotus pulmonarius SMC to significantly reduce pentachlorophenol (PCP) levels [67].…”

It is the process by which a material is broken down into its constituent parts by the activity of microorganisms, such as bacteria, in a biochemical reaction 40 . Biodeterioration, bio fragmentation, and assimilation are the three primary steps of the biodegradation mechanism 41 .…”
