Life Cycle Assessment Analyzing With Gabi Software for Food Waste Management Using Windrow and Hybrid Composting Technologies

Abstract

The use of composting technologies to treat food waste (FW) now represents an environmentally friendly form of waste treatment, in which organic matter can decompose biologically. However, the damaging emissions of composting technologies for FW treatment vary, thus a life cycle assessment (LCA) approach is often used to certify the quality of the decision-making process. This study quantifies and compares the environmental impact of two scenarios in Malaysia: windrow and hybrid composting (windrow integrated with a landfill) technologies. The scenario modeling was performed via GaBi v6.0 software using 1 ton of pre-treated FW as a functional unit, with the analysis based on the ReCiPe (H) v1.07 characterization method. The midpoint results revealed that windrow composting technology has a lower environmental impact and is an environmentally friendly option compared to hybrid technology. Treating FW in a windrow scenario has relatively low power requirements for operation with the added advantageous properties of compost production, and a substantial reduction in the distances transferred by the road. The hybrid scenario had the largest negative environmental impact in all categories, such as climate change (1.45E+03 kg CO2 eq), and ozone depletion (4.39E-09kg CFC-11 eq) because of the energy-intensive waste collection and treatment activities it needs, and with no landfill gas filtration. Finally, based on the single score synthesis, windrow is considered as an appropriate treatment with the avoidance of Resource Depletion (6.61E+02 Pt).

Systematic Review and Meta-Analysis on the Use of LCA to Assess the Environmental Impacts of the Composting Process

“…Midpoint categories are based on unique environmental issues and are associated with problem-oriented methods. The endpoint categories are concerned with the characterization of the intensity and implications of midpoint impacts and are known by damage-oriented methods [78]. Some impact categories associated with the midpoint and endpoint are presented in Table 8 [86,87].…”

“…Some impact categories associated with the midpoint and endpoint are presented in Table 8 [86,87]. The LCA framework is often modelled using LCA software, which will quantify and evaluate the environmental loads of the entire system using characterization methods [78,85]. Table 9 presents the characterization methods used in the analysed studies for composting, which includes CML, EDIP 2003, ReCiPe, ILCD 2011, TRACI, IPCC 2013, and Eco-Indicator.…”

Assessing The Effects of Microorganisms (EM) and Bokashi on Okra (Abelmoschus esculentus L. Moench) Towards Plant Growth and Yield Performance

“…Bokashi production originated in East Asia but has spread to agricultural societies in South and Central America. Due to various environmental concerns, it consists of malodour control in composting, improved water quality, and heavy metal remediation from earth soils (Abu et al, 2021).…”
