Food Waste Recycling

Food waste recycling attracts people's attention recently. Fiber such as vegetable stem vegetable is main ingredient of food waste. How to use this resource becomes an important topic. In this manuscript, six ethanol-producing yeasts were isolated from sewage sludge, soil and rotten fruits, then examined using PDA medium, TTC screening, and Duchenne tube fermentation experiments. After screeing on D-xylose medium, an ethanol-producing yeast Y9, Saccharomyces cerevisiae, was isolated. Ethanol production over time by strain Y9 indicated that 12 days is the screened strain's optimal fermentation time. The screened strain's specific growth rate is 0.12 h–1, and its ethanol productivity is higher than that of store-bought Angel Yeast or its co-culture, which indicated inhibition existing among the strains. Moreover, the ethanol productivity in shaken samples was higher than that in static samples, indicating that slight oxygen conditions benefited the screened strain's ethanol production. The results may have implications in ethanol production and the treatment of sewage sludge and food waste.

The Impact

Hotels face many issues related to food waste management, which is considered a serious environmental and socioeconomic issue in the 21st century. The improper disposal of food waste causes greenhouse gases emissions, consequently badly affecting the environment. This research aims to measure the impact of customer trends in changing the pattern of food waste disposal and recycling into bioenergy relating to hotel purposes and contributing to reducing hotel energy costs in Egypt. Two survey questionnaires were designed for hotel managers and guests, with 25 and 300 forms, respectively. The results indicated that hotel managers are highly willing to recycle food waste to produce bioenergy and hence play an effective role in environmental preservation. Such alternative energy sources are less expensive than conventional ones. This study revealed guests’ intentions to participate in the process of preserving the surrounding environment, as well as their preferences to stay in hotels that are practicing food waste recycling operations. Limitations can be seen in the lack of advertising for such hotels as well the high cost of staying in green and ecological hotels.
