The manufacturing industry and its relationship with sustainable development simply cannot be separated. Especially, when the government started to show their attention by giving various obligations for the manufacturing industry to implement sustainable development principles, such as the obligation of the company to conduct a social and environmental responsibility by making sustainability report, the environmental impact assessment (AMDAL) report, to participate in various sustainability programs such as Corporate Performance Rating Program (PROPER) and Green Industry Award. There are so many indicators and data that need to be collected in order to fulfill these obligations. It certainly may charge the company in terms of time, yet the number of indicators and the data required were similar between one report to another. There is still no particular design to be able to resolve the issue. Therefore, the aim of this study is to design an integrated data management system for sustainability reporting needs and sustainability programs which has the end result of an application prototype of a system that can help companies, especially in the manufacturing industry to create reporting even more efficient. Data management is done by combining all four types of reporting and program which are Global Report Initiative sustainability report, the AMDAL report, Green Industry program, and PROPER. The prototype is made based on the results of data management using Microsoft Access to store data and to produce four types of summary reports. In the end of the study, it can be concluded that, overall, the system can be implemented and by the withdrawal of three respondents review, the system can improve the efficiency of the company in preparing sustainability reporting. In the evaluation phase, it is found a related method that can be used as the basis to do before making reporting in order to make them more easily 40.98%, that is Life Cycle Assessment.

Sri Lanka has been renowned for its top quality natural rubber products. Among the locally manufactured raw rubber types, ribbed smoked sheets (RSS) hold a significant position as it entails ca. 50% of total natural rubber production in island. With no sufficient information on effectiveness in the use of materials and finance and then environmental impacts of RSS manufacture, this study aimed at assessing RSS manufacturing process adopting Material flow analysis, Material flow cost accounting and environmental Life cycle assessment in three factories in view of providing effective suggestions for making the system to be more cost efficient and environmentally friendly. Results indicated that manufacture cost, financial loss and GHG emissions generated by processing 1 MT of RSS were LKR 104,004 ± 6,336, LKR 1,007 ± 44 and 38.0 ± 2.1 kg CO2e, respectively (mean ± standard error). As an improvement option, installing single-day smoke dryers was proposed. This option could reduce firewood consumption per 1 MT of RSS by ca. 30% resulting in 0.1% and 14% of reductions in manufacture cost and GHG emissions, respectively. Implications of these findings are also discussed.

Dairy processing industry is one of the industries that give positive contribution to the economic growth, however it also contributes in many impacts on the environment, as well as milk powder product manufactured by PT X. The main objective of this study was to determine the most significant environmental impact caused by production and transportation of milk powder in bag 250 gram (Product X) using Life Cycle Assessment (LCA) methodology. The boundary of the LCA study is “cradle to gate”, including: materials production, materials transportation from supplier to the PT X factory, manufacture of milk powder in PT X, and distribution of the products from factory to distributor. Four impact categories will be calculated on this study: global warming potential (GWP), eutrophication potential (EP), acidification potential (AP), and photochemical oxidant creation potential (POCP). The impact assessment was calculated by software SimaPro v.8.3.2 faculty license, and the calculation result validated manually by Microsoft Excel. The result of environmental impact calculation showed the GWP, EP, AP, and POCP of 1 kg milk powder is 1.3245 kg CO2 eq/kg, 0.0033 kg PO43- eq/kg, 0.0066 kg SO2 eq/kg and 0.0020 kg C2H4 eq/kg. The material production subsystem has the highest environmental impact on GWP, POCP, AP and EP categories. In particular, production activity in PT X also contributes to GWP. An environmental impact reduction strategy can focus on reducing GWP with electricity usage efficiency and developing a material supplier selection plan with environmental impacts of material production as one of criteria.

Life cycle assessment (LCA) refuse derived fuel (RDF) waste in pusat inovasi agro teknologi (PIAT) Universitas Gadjah Mada as alternative waste management for energy Titi Tiara Anasstasia; Muhammad Mufti Azis; Imam Haryanto; Rio Arya Pratama

Pusat Inovasi Agroteknologi (PIAT) handles institutional waste generated from Universitas Gadjah Mada (UGM). Waste from UGM is called Institutional Solid Waste (ISW) reaches 1,427.27 kg / week. In this study, Life Cycle Assessment (LCA) analysis was used as a tool to calculate and evaluate the environmental impact of potential ISW conversion to densified Refused Derived Fuel (dRDF) with gate to gate framework system. For simulation, OpenLCA software equipped with Ecoinvent database was used in this work. The results showed that conversion of combustible inorganic waste into densified Refuse Derived Fuel (dRDF) along with conversion of organic waste into compost gave following environmental impacts: global warming potential of 1.3E+00 kg CO2 eq, acidification 3.9E-03kg SO4 eq., eutrophication 7.1E-01 kg P eq., human toxicity 1.2E+00 kg 1.4-dichlorobenzene and terrestrial ecotoxicity 6.1E-02 kg 1.4-dichlorobenzene. By separating combustible from non-combustible inorganic waste may significantly improve the quality of dRDF as well as the quantity of compost. The substitution of coal using dRDF combined with the selling of compost is a feasible option. In addition, our results also showed that installation of exhaust gas emission control could further reduce the environmental impact of dRDF production. An economic evaluation was also conducted to evaluate the scenario of converting ISW into dRDF and compost. This option appeared to be profitable, provided that no restrictions to the processed waste, steady flow of dRDF product to the end-users, and the presence of standard price for dRDF.

Water footprint evaluates impacts associated with the water use along a product’s life cycle. In order to quantify impacts resulting from water pollution in a comprehensive manner, impact categories, such as human toxicity, were developed in the context of Life Cycle Assessment (LCA). Nevertheless, methods addressing human health impacts often have a low spatial resolution and, thus, are not able to model impacts on a local scale. To address this issue, we develop a region-specific model for the human toxicity impacts for the cotton-textile industry in Punjab, Pakistan. We analysed local cause-effect chains and created a region “Punjab” in the USEtox model using local climate, landscape, and population data. Finally, we calculated human health impacts for the emissions of pesticides from the cotton cultivation and heavy metals from the textile production. The results were compared to that obtained for the region India+ (where Pakistan belongs) provided by USEtox. The overall result obtained for Punjab is higher than that for India+. In Punjab, the dominant pathway is ingestion via drinking water, which contributes to two-thirds of the total impacts. Nevertheless, the USEtox model does not reflect the local cause-effect chains completely due to absence of the groundwater compartment. Since groundwater is the main source for drinking in Punjab, a more detailed analysis of the fate of and exposure to the pollutants is needed. This study demonstrates that a region-specific assessment of the water quality aspects is essential to provide a more robust evaluation of the human health impacts within water footprinting.
