Inventory Analysis

Life cycle assessment (LCA) is used frequently as a decision support tool for evaluating different design choices of products based on their environmental impacts. A life cycle usually comprises several phases of varying timespan. The amount of emissions generated from different life cycle phases of a product could be significantly different from one another. In conventional LCA, the emissions generated from the life cycle phases of a product are aggregated at the inventory analysis stage, which is then used as an input for life cycle impact assessment. However, when the emissions are aggregated, the temporal variability of inventory data is ignored, which may result in inaccurate environmental impact assessment. Besides, the conventional LCA does not consider the environmental impact of circular products with multiple use cycles. It poses difficulties in identifying the hotspots of emission-intensive activities with the potential to mislead conclusions and implications for both practice and policy. To address this issue and to analyse the embedded temporal variations in inventory data in a CE context, the paper proposes to calculate the emission intensity for each life cycle phase. It is argued that calculating and comparing emission intensity, based on the timespan and amount of emissions for individual life cycle phases, at the inventory analysis stage of LCA offers a complementary approach to the traditional aggregate emission-based LCA approach. In a circular scenario, it helps to identify significant issues during different life cycle phases and the relevant environmental performance improvement opportunities through product, business model and supply chain design.

The Impact

Coffee is one of Indonesia's leading commodity that has the potential to be developed for agro-industry. High coffee production has encouraged the establishment of a small and medium coffee industry. The purpose of this study is to analyze possible strategies for implementing cleaner production and evaluate the impact on the environment using Life Cycle Assessment (LCA) method with a gate to gate scope. The stages of cleaner production research used quick scan techniques, source identification, cause evaluation and option generation implementation. LCA research stages with the determination of the objectives and scope of research, inventory analysis, environmental impact assessment and implementation of improvements. Greenhouse gases (GHG) emission was assessed as an environmental impact parameter. The results showed the alternative potential for cleaner production that was applied the manufacture of drying domes (Payback Period/PBP) 3.18 months with an investment ofRp. 2,285,000), procurement of generator machines (PBP 1.16 months with an investment of Rp. 5,860,000), making air circulation in roasting room (PBP 0.07 months with an investment of Rp. 1,268,000), making of solid waste composting reactor (PBP 2.18 months with an investment of Rp. 3,440,000) and addition packing equipment (PBP 0.45 month with an investment of Rp. 3.057 .000). The results of the LCA analysis show that 1,000 Kg of dry-processed coffee requires energy of 869.92 MJ and produces GHG emissions of 95.58 Kg CO₂eq / ton coffee fruits or 0.42Kg CO₂eq / Kg coffee powder equal to 2.389Kg CO₂eq/month and 28.674Kg CO₂eq/year.Key words : environmental impact assessment, life cycle assessment, small coffee industries

Analysis Tool

Planning urban expansion under the interconnected Sustainable Development Goals requires a systemic analysis of its environmental impacts. The benefits of integrating the widely used system analysis tool life cycle assessment (LCA) into the planning process tool environmental impact assessment (EIA) are described in the literature. However, not many applications of such an integration have been conducted. The aim of this study is to refine the framework for integrating LCA into the process of EIA and to apply this framework to an example of urban expansion: Masdar City in Abu Dhabi. The integrated framework builds on the complementarity between the scope and assessment steps of the tools and assesses the impacts for the areas of protection: human health, ecosystem, and resources. The framework is then applied to the vehicles, buildings, and infrastructure in the city’s first development phase (DP1). Major environmental stressors include the loss of existing desert ecosystem and the utilization of non-renewable sources of energy at various development stages of DP1. Substituting natural gas-based electricity with solar power could potentially save 46% of current carbon emissions. To mitigate the land transformation impacts, construction of “close-to-nature” artificial habitats, and increased use of low-carbon fuels is suggested.

There is a major international effort to improve the availability of data for life cycle assessment (LCA), as these assessments have become one of the main pillars driving European policy with respect to the sustainable use of resources. However, there is still a lack of data even for Europe. This study presents a cradle-to-farm gate assessment, or LCA, of winter and spring rapeseed produced in the northern European country of Latvia. The LCA model is based on an in-depth and up-to-date agricultural practice used in the region and covers the time span of 2008–2016. An LCA of rapeseed oil produced by cold pressing was carried out. The environmental impact assessment was calculated with the ReCiPe impact assessment method version 1.03, a hierarchical (H) perspective, along with the cumulative energy demand method v1.11. Cultivation of winter rapeseed has a lower environmental impact than cultivation of spring rapeseed due to higher agricultural inputs and higher yield. The greatest impact is on human health. Mineral fertilizers (production and application) and agricultural machinery are responsible for the greatest environmental impact. The results for the mill stage of rapeseed oil demonstrated that the choice of the allocation method has a significant impact on the environmental performance results.

The Impact

Kenaf fiber from the kenaf plant is the excellent raw material for industry because of the various diversified products it produces. To develop sustainable kenaf fiber, information is needed on the strengths and weaknesses of kenaf cultivation systems with respect to productivity and environmental impact. Therefore, a comprehensive environmental and economic impact assessment was conducted from cultivating kenaf to kenaf fiber. The environmental impact assessment uses the Life Cycle Assessment (LCA) method and economic calculations from the life cycle of kenaf to kenaf fiber to collectors use the Life Cycle Cost (LCC) method. The calculation of environmental impacts is in accordance with the stages of ISO 14040, using a single score assessment. The LCA results show that the treatment stage is the highest contributor of the three groups of impact categories. The highest to the lowest in the impact category group that was influenced by the treatment stage were resources with a value of 21.4 mPt, human health with a value of 8.76 mPt, and ecosystem quality with a value of 1.91 mPt. The cost identified through the LCC is Rp. 6,088,468,333, NVP and B/Cnet are positive. The results of the sensitivity analysis if there is a reduction in production> 6%, the business is still profitable and can be run.
