Calcium, an important mineral in bones, is widely available the form of calcium carbonate (CaCO₃) eggshells. However, tonnes eggshells have been wasted every year all around globe. The current work was aimed at valorizing eggshell waste and incorporating it as alternative Ca source for deficient people. Soup mixes (named 1-5) were formulated by varying ratio starch (4-12 g) vegetables (2-10 alo...

Cultivation of OYSTER MUSHROOM (Pleurotus tuber-regium) on selected organic waste was carried out in the Microbiology Laboratory, Faculty of Science of the University of Port Harcourt. The study evaluated the effect of selected organic wastes on the growth and yield of Pleurotus tuber-regium (Fr. Singer). The organic wastes (Dry Substrates which include Maize cob, Cassava peelings, Plantain pee...

Pleurotus ostreatus (P. ostreatus) is considered a high-quality food, rich in proteins and bioactive compounds important for maintaining human health. Lately, commonly used substrate oyster mushroom cultivation—wheat straw, more often replaced by alternative cellulose substrates originated from the agricultural food industry. Utilization of wastes cultivation has its added value: sustainable wa...

It is estimated that there are over 5,000 species of mushrooms worldwide. Some of them are edible and some are poisonous due to containing significant toxins. In more than 95% of mushroom toxicity cases, poisoning occurs as a result of misidentification of the mushroom by an amateur mushroom hunter. The severity of mushroom poisoning may vary, depending on the geographic location where the mush...

Our paper analyzes the strengths and weaknesses of a subfield of industrial ecology called integrated bio-systems (IBS). Consistent with the principles of industrial ecology, the goal of an IBS is to reduce pollution by transforming linear material flows into closed, cyclical processes that produce value-added product. The presence of large, concentrated quantities of compost, generated as a re...
