Although recycled polymers and reinforced polymer composites have been in use for many years there is little information available on their environmental impacts. The goal of the present study is to analyze the environmental impact of new composite materials obtained from the combination of recycled thermoplastics (polypropylene [PP] and polyethylene [PE]) with mineral fillers like talc and with glass fiber. The environmental impact of these composite materials is compared to the impact of virgin PP and PE. The recycled and virgin materials were compared using life cycle assessment method according to their environmental effects. Within the scope of the study, GaBi software was used for Life Cycle Assessment (LCA) analysis. From cradle-to-grave life cycle inventory studies were performed for 1 kg of each of the thermoplastics. Landfilling was considered as reference scenario and compared with filled recycled plastics. A quantitative impact assessment was performed for four environmental impact categories, global warming (GWP) over a hundred years, human toxicity (HTP), abiotic depletion (ADP) and acidification potential (AP) were taken into consideration during LCA. In the comparison of recycled and virgin polymers, it was seen that recycling has lower environmental effect for different impact assessment methods like acidification potential, abiotic depletion, human toxicity and global warming.

Abstract Tofu is one of the processed soybean foods that are very popular with Indonesian society. Despite the popularity of Tofu, Tofu production in Indonesia is generally small and medium, reaching 500 kg per day, as in the tofu factory in Semanan, West Jakarta. The purpose of this study is to analyze the environmental impact of tofu production in West Jakarta. The life cycle assessment (LCA) approach was used to achieve this goal with SimaPro software for impact calculations. This research applies the LCA cradle to gate, which consists of soybean cultivation, transportation, and tofu production processes. The environmental impacts of tofu production analyzed in this study include global warming, ozone depletion, acidification, and eutrophication. The impact analysis showed that the acquisition of soybeans, which consisted of soybean cultivation and transportation, had the most significant environmental impact with a global warming potential value of 0.882 kg CO2 eq out of a total of 0.978 CO2 eq for the whole process.

AbstractThe energy balance and life cycle assessment (LCA) of ohmic heating and appertization systems for processing of chopped tomatoes with juice (CTwJ) were evaluated. The data included in the study, such as processing conditions, energy consumption, and water use, were experimentally collected. The functional unit was considered to be 1 kg of packaged CTwJ. Six LCA impact assessment methodologies were evaluated for uncertainty analysis of selection of the impact assessment methodology. The energy requirement evaluation showed the highest energy consumption for appertization (156 kWh/t of product). The energy saving of the ohmic heating line compared to the appertization line is 102 kWh/t of the product (or 65% energy saving). The energy efficiencies of the appertization and ohmic heating lines are 25% and 77%, respectively. Regarding the environmental impact, CTwJ processing and packaging by appertization were higher than those of ohmic heating systems. In other words, CTwJ production by the ohmic heating system was more environmentally efficient. The tin production phase was the environmental hotspot in packaged CTwJ production by the appertization system; however, the agricultural phase of production was the hotspot in ohmic heating processing. The uncertainty analysis results indicated that the global warming potential for appertization of 1 kg of packaged CTwJ ranges from 4.13 to 4.44 kg CO2eq. In addition, the global warming potential of the ohmic heating system ranges from 2.50 to 2.54 kg CO2eq. This study highlights that ohmic heating presents a great alternative to conventional sterilization methods due to its low environmental impact and high energy efficiency.

Geothermal Power

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

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.

The Impact

Dumping of municipal solid waste into uncontrolled dumpsites is the most common method of waste disposal in most cities of India. These dumpsites are posing a serious challenge to environmental quality and sustainable development. Mumbai, which generates over 9000 t of municipal solid waste daily, also disposes of most of its waste in open dumps. It is important to analyse the impact of municipal solid waste disposal today and what would be the impact under integrated waste management schemes. In this study, life cycle assessment methodology was used to determine the impact of municipal solid waste management under different scenarios. Six different scenarios were developed as alternatives to the current practice of open dumping and partially bioreactor landfilling. The scenarios include landfill with biogas collection, incineration and different combinations of recycling, landfill, composting, anaerobic digestion and incineration. Global warming, acidification, eutrophication and human toxicity were assessed as environmental impact categories. The sensitivity analysis shows that if the recycling rate is increased from 10% to 90%, the environmental impacts as compared with present scenario would reduce from 998.43 kg CO2 eq t−1 of municipal solid waste, 0.124 kg SO2 eq t−1, 0.46 kg PO4−3 eq t−1, 0.44 kg 1,4-DB eq t−1 to 892.34 kg CO2 eq t−1, 0.121 kg SO2 eq t−1, 0.36 kg PO4−3 eq t−1, 0.40 kg 1,4-DB eq t−1, respectively. An integrated municipal solid waste management approach with a mix of recycling, composting, anaerobic digestion and landfill had the lowest overall environmental impact. The technologies, such as incineration, would reduce the global warming emission because of the highest avoided emissions, however, human toxicity would increase.

Use Of Resources

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.
