Indonesia introduced new policies, like PROPER, that require companies to develop LCA capacity. Currently, LCA expertise is still developing. Therefore, the question arises how the development of LCA expertise and a growth of LCA Practitioners can be achieved. In this article learnings and key success factors from global best practices are identified and illustrated based on case studies. The key success factors are 1) harmonization and guidance, 2) capacity building, 3) focus on business value and 4) ease of use. These Key Success Factors can give Indonesia and its LCA practitioners a head start in implementing and embedding LCA in policy implementation and compliance by private companies. Developing a program that provides the following six elements a) Introduction to LCA training, b) Training for managers and policy makers, c) Learning by doing with screening LCAs, d) Facilitate easy to use tools, e) Develop Product Category Rules (PCR) and f) Create a label or other verified report/certificate can accelerate the development of LCA expertise and the implementation of LCA practices.

Life Cycle Assessment Approach on Food Packaging to Build Sustainable Consumption Awareness in Developing Countries NiLuh Widyaningsih

Household consumption is the value of products bought by the household. Consumption takes the biggest part in our lives to support our basic needs on food, clothe, and shelter. The products packaging do not come from natural anymore but from the man-made, such as paper, plastic, glass or metal. Most of the packaging become waste into the environment. There are organic and inorganic waste. The increasing number of population will increase the demand on the products and it will create more waste. Indonesia is the 4th most populated country in the world and it has still waste management problems in urban and rural area. In 2014 from my research, Jakarta has higher percentage on non-food than on food consumption but the contribution from food products into the local economy gets higher every year. We can see this phenomena almost in every place. This research used qualitative approach to gather data and information regarding people’s perception about household solid waste from their consumption behavior. The data do not available on the lower level adminitration. From the focus group discussion in Setia Asih Village (Bekasi) showed that local people and government have less knowledge on household solid waste, especially the life cycle via food packaging and how to treat the waste. So, I build a concept to solve the mind-set issue on the sustainable consumption awareness through the life cycle assessment approach. Local people and government can used it to improve their quality of life (social and economy) and environmental condition.

Geothermal potential in Indonesia estimate can produced renewable energy 29 GW, and until 2016 it still used 5% or about 1643 MW in. From that result, about 227 MW produced by Wayang Windu geothermal power plant. The Input were raw material, energy and water. These input produced electricity as main product, by product, and also other output that related to environment i.e. emission, solid waste and waste water. All environmental impacts should be controlled to comply with environmental standard, and even go beyond compliance and perform continual improvement. This research will use Life Cycle Assessment method based on ISO 14040 and use cradle to gate concept with boundary from liquid steam production until electricity produced, and Megawatt Hours as the functional unit. Life Cycle Inventory has been done with direct input and output in the boundary and resulted that subsystem of Non Condensable Gas and condensate production have the largest environmental impact. LCI also show that every MWh electricity produced, it needed 6.87 Ton dry steam or 8.16 Ton liquid steam. Global Warming Potential (GWP) value is 0.155 Ton CO2eq./MWh, Acidification Potential (AP) 1.69 kg SO2eq./MWh, Eutrophication Potential (EP) 5.36 gPO4 eq./MWh and land use impacts 0.000024 PDF/m2. Life Cycle Impact Assessment resulted that AP contribute 78% of environmental impact and 98% resulted from H2S Non Condensable Gas. Comparison results with another dry steam geothermal power plant show that impact potential result of the company in good position and there’s a strong relation between gross production, GWP and AP value.Keywords: Life cycle assessment; Geothermal; Continual Improvement; Global Warming Potential; Acidification Potential

AbstractIndonesia is a country with the largest number of tempeh producers in the world. However, the practice of tempeh production by most entrepreneurs has not paid enough attention to environmental aspects. In this study, Life Cycle Assessment (LCA) was used as a method to assess the environmental impact of tempeh labeled as hygienic, produced by Rumah Tempeh Indonesia (RTI) located in Bogor, West Java. The hygienic tempeh consists of two types, namely one made of local soybean (Tempeh Sehat) and the other made of imported soybean (Tempeh Kita). The extent of the environmental impact, in the form of GHG emissions and energy efficiency, throughout the life cycle of tempeh is calculated, analyzed and some improvement scenarios are proposed. The life cycle of tempeh is limited to soybean cultivation, raw material transportation and tempeh processing at RTI. The results show that Tempeh Sehat generates GHG emissions of 0.323 kg CO2-eq, while Tempeh Kita is 0.555 kg CO2-eq per kg of product. The hotspots that contribute to GHG impacts are identified as originating from the stages of soybeans transportation and tempeh processing. Energy efficiency is indicated by the Net Energy Value (NEV) and the Net Energy Ratio (NER) of both types of products. Tempeh Sehat has NEV of 2.064 MJ, while Tempeh Kita is 0.318 MJ. Both types of products show the value of NER>1. Further analysis of existing production practices has led to several scenarios of improvement and their environmental effects have been discussed. Keywords: Tempeh; LCA; GHG emission; energy efficiency

Life Cycle Assessment of Silicon-Based Tandem Solar Photovoltaics and their End-of-Life Marina Moneiro Lunardi; Juan Pablo Alvarez-Gaitan; Jose Bilbao; Richard Paul Corkish

The rapid global uptake of solar photovoltaics (PV) promises the hope of affordable low-carbon electricity. Most production of PV modules so far, and for the foreseeable future, has been based on silicon wafer cells and while there are further R&D outcomes still to be fully transferred to the silicon cell industry, the next major technology change is likely to be the addition of a thin-film top cell to form an efficient tandem device. The authors have applied life cycle assessment (LCA) to several of the current and potential mass manufactured solar cell technology choices, including different silicon wafer styles and silicon/thin-film tandems. We have demonstrated that the environmental benefits of some paths for efficiency improvements, particularly of the incorporation of atomic hydrogen into silicon wafers, more than compensate for the additional inputs required. Furthermore, we have shown that the stability of top-cell materials for tandems is paramount, to avoid the premature demise of the underlying silicon bottom cell.The end-of-life has been assumed to be landfill in most preceding LCA studies but there is a growing global need for PV recycling due to the rapid rise in uptake of photovoltaics, which will result in a significant future waste stream. Europe is leading the world in requiring industry stewardship for photovoltaics (and batteries, inverters and other system components) and other jurisdictions, including Australia, are following. However, photovoltaic modules are difficult to dismantle or deconstruct for materials recovery by methods that are both financially and environmentally sustainable. We will use LCA to guide our research on module recycling by chemical, thermal and mechanical methods and their combinations, with an aim to maximize the value of the recovered materials.
