Abstract

Composting, a crucial process in sustainable waste management, transforms organic matter into nutrient-rich compost, which is an organic byproduct of the decomposition process known as composting. Compost serves as a sustainable means of recycling various organic materials into a nutrient-rich soil conditioner, finding applications in gardens, landscaping, horticulture, urban agriculture, and organic farming. This paper investigated the complex factors affecting the maturity of compost, focusing on parameters such as temperature, pH, and moisture content. The breakdown rates of eight carefully regulated combinations were compared to a sample that had not been altered. The analytic results showed the volume loss over time was a critical component in determining the maturity of compost. Combinations two (Temperature=High, Moisture Content=High, pH=Low), three (Temperature=High, Moisture Content=Low, pH=High), and four (Temperature=High, Moisture Content=Low, pH=Low) showed the most percentage volume loss by day 46, indicating faster maturation compared to the uncontrolled group. In this volume loss comparison, the circular truncated cone formula played a crucial role in revealing the ideal combinations for compost maturation. This comprehensive study not only contributed valuable insights into optimizing composting conditions but also highlighted the diverse applications of compost. By examining the complex interactions between pH, moisture content, and temperature, this study enhanced our knowledge of sustainable waste-to-resource operations and effective composting techniques.

Abstract

This paper presents a study on household waste management and recycling awareness. Residential areas are the major sources of solid waste as that is where people live. The waste that is usually disposed of from residential areas includes food waste, plastic waste, paper, glass, tin, and others. The increasing trend in waste generated from homes has become a major concern. This study aimed to assess household waste management and recycling awareness in two residential areas located in Padang Terap District, Kuala Nerang, Kedah, Malaysia. Recently, Padang Terap district showed an increase in waste generated compared to another district, Kedah. An open-ended questionnaire was distributed to approximately 32 respondents, and an interview was conducted to study household waste management and recycling awareness in two residential areas—Taman Jati and Taman Pelangi. The research shows that household waste management to segregate the waste remains a problem, despite most respondents being aware of this issue through different media. Furthermore, the lack of household waste management and recycling programs and facilities by the local authorities caused residents to be reluctant to practice these activities.
