Abstract

Background and Objectives:Nowadays vermicompost production of food wastes is posed as one of appropriate methods to food wastes. disposal, its production used in agriculture and gardening. Moreover this process has some by products beside useful fertilizer that one of them is the worms. we can use them in variety of products specially in production of poultry and fish food. So determination of optimal condition for operating vermicompost production process of food wastes and worms. growth in these wastes is important. The aim of this study was determination of optimal temperature and moisture range for process progression in vermicompost production of food wastes.
Materials and Methods: In this study we used Eisenia foetida species. Process performed in pots with 15 cm (h) and 12 cm (d) and in a mouth period of time. Three ranges of temperature including 5-15, 15-25, 25-35 oC and three ranges of moisture including 55-65%, 65-75%, 75-85% were applied in this study.
Results: Multivariate analysis was used for analyze of results and it showed that influence of temperature and moisture on C:N ratio is significant in vermicomposting process (p <0.05).
Conclusion: The results showed that the range of temperature 15-25 oC is more appropriate for operating of process. Due to these study.s results with increasing or reduction of ambient temperature, like summer and winter, conservation of moisture around the range of 65-75 %, is effective in better performance of the process. According to this study.s results, it seems that the temperature of 15- 25 oC and moisture of 65-75% are better conditions for worm.s growth.

Abstract

Background and Objective: Although cultural and educational challenges contribute to the rising levels of food waste, public participation plays a crucial role in its fundamental management. This study aims to investigate the significance of citizen engagement and to develop a behavioral model for sustainable household food waste management in Tehran.
Materials and Methods: This study adopts a quantitative research paradigm and was conducted using a survey method. The statistical population comprised 2,239,907 households in Tehran, from which a sample of 384 households was selected based on Krejcie and Morgan’s sampling table, using a stratified random sampling method with proportional allocation. Data were collected through a researcher-designed questionnaire, the content and face validity of which were confirmed by a panel of professors in agricultural extension and education, as well as experts in waste management. The reliability of the questionnaire was supported by Cronbach's alpha values ranging from 0.78 to 0.92. Path analysis using structural equation modeling (SEM) in LISREL software was employed to evaluate the predictive power of the independent variables on the dependent variable.
Results: According to the results of the path analysis and the R² statistic, the variables of citizens' intention toward sustainable food waste management, environmental attitude, environmental awareness and knowledge, place attachment, satisfaction, and social trust collectively explained 67% of the variance in citizens' participatory behavior related to sustainable food waste management.
Conclusion: The findings indicate that citizens' environmental awareness and attitudes play a significant role in their participation in sustainable food waste management. In other words, individuals with greater knowledge of the environmental consequences of food waste are more likely to adopt effective waste management practices. Therefore, the development and implementation of targeted educational programs aimed at enhancing public awareness and fostering positive environmental attitudes are essential. Such initiatives can significantly contribute to encouraging participatory behaviors in sustainable food waste management.
