Assessment Results

Using environmentally friendly materials in the technological process of bottle production fits perfectly into the idea of sustainable development. The use of natural raw materials as well as conscious energy consumption are strategic aspects that should be considered in order to improve the effectiveness of the bottle moulding process. This paper presents a new and structured approach to the analysis of uncertainty and sensitivity in life cycle assessment, one developed in order to support the design process of environmentally friendly food packaging materials. With regard to this “probabilistic” approach to life cycle assessment, results are expressed as ranges of environmental impacts, and alternative solutions are developed while offering the concept of input uncertainty and the effect thereof on the final result. This approach includes: (1) the evaluation of the quality of inputs (represented by the origin matrix); (2) the reliability of results and (3) the uncertainty of results (the Monte Carlo method). The use of the methodology is illustrated based on an experiment conducted with real data from the technological process of bottle production. The results provide insight into the uncertainty of life cycle assessment indicators regarding global warming, acidification and the use of arable fields and farmland.

Wine Bottle

Natural stoppers are a magnificent closure for the production of aging wines and unique wines, whose application is limited by the availability of raw materials and more specifically of cork sheets of different thickness and quality. The growing demand for quality wine bottle closures leads to the search for alternative stopper production. The two-piece stopper is an alternative since it uses non-usable plates in a conventional way for the production of quality caps. The present study has analyzed the impact of the manufacture of these two-piece stoppers using different methodologies and for different dimensions by developing an LCA (Life Cycle Assessment), concluding that the process phases of the plate, its boiling, and its stabilization, are the phases with the greatest impact. Likewise, it is detected that the impacts in all phases are relatively similar (for one kg of net cork produced), although the volumetric difference between these stoppers represents a significant difference in impacts for each unit produced.

Assessment Approach

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.

The Impact

Firstly global warming issue caused by greenhouse gas emissions (CO2) which comes from human activities. Along with increasing of daily need, that humans of activities food produce is also increase, include of tofu. Tofu is a traditional Indonesian specialty made from soybeans and used as a side dish. The purpose of this study was to determine the impact of global warming from tofu products on Mampang Prapatan's Small Tofu and Medium Enterprises. The method used in this study is the Life Cycle Assessment (LCA) method with the help of Simapro 8.4 software with a 1 kg tofu functional unit. The data collected in this study is the average data of tofu production for 3 months, namely January - March 2018. The LCA data in this study include the process of soybean cultivation, transportation processes for shipping soybeans, water, fuel wood, and electricity use. The limitations of this study are from cradle (soybean cultivation) to gate (tofu products).The results showed that UKM Mampang Prapatan has the potential impact of global warming with a value of 3.84 kg CO2-eq, while the value of global warming in the production process knows the scenario of wastewater treatment and the use of Liquefied Petroleum Gas (LPG) as fuel for boiling pulp 4.49 kg CO2-eq soybeans. Based on the results of this study, greenhouse gas (CO2) emissions are issued; the intervention that can be done is to optimize the use of raw materials for production to reduce the impact of CO2-eq kg global warming.

Reflective Foil

In the last twenty years, the exploitation of non-renewable resources and the effects of their applications on environment and human health were considered central topics in political and scientific debate on European and worldwide scale. This kind of resources have been used in different sectors, as energy systems, technological research, but also in private/public buildings and production of consumer goods, involving significantly domestic and ordinary life of every human being. Studies about the effect of this exploitation carried out discouraging results, in terms of climate changes and energy sustenance; this determined a progressive approach process to a new concept of development, able to couple the qualitative standard of modern life with the respect of planet and its inhabitants. Starting from this reflection, scientific community moved towards research on alternative resources and developed a new way to conceive planning process and technical innovations, in order to exploit renewable energies and recycled materials, promote energy savings and reduce environmental pollution. In this context the present paper aims at evaluating benefits relating to different solutions of thermal insulation in building envelope. In fact a high grade of insulation ensures better comfort conditions in inner spaces, reducing energy consumptions due to heating and cooling conditioning. The paper presents the results of a detailed Life Cycle Assessment (LCA) of the reflective foil ISOLIVING, conceived and produced by an Italian company. The Life Cycle Assessment methodology allows to consider all stages of the life cycle, from the extraction of raw materials to the product’s disposal, in an optics “from cradle to grave.” In particular, the study takes into account the production phase of the reflective foil ISOLIVING, the installation phase, the transport of all components to the production site and also the end of life scenario of the material. The possibility to collect many detailed information about the production phase adds value to the study. The analysis is carried out according to UNI EN ISO 14040 and UNI EN ISO 14044, which regulate the LCA procedure. The LCA modeling was performed using SimaPro software application. The results of the analysis allow to make an important comparison concerning the environmental performances, between the reflective foil ISOLIVING and other types of insulating materials.

The life cycle of a polypropylene stacking chair is assessed in order to represent the environmental impact of a plastic product. The analysis is categorized into two phases, manufacturing and disposing. The manufacturing process of a chair concerns a prime material, polypropylene (PP) granulate, an injection molding process and a resource, electricity. According to the assessment, the PP granulate seems to contribute the highest impact on the environment in term of the fossil fuel used. Afterwards, the landfill method is used in the disposal scenario of waste, and the analysis shows that the highest impact comes in the form of carcinogens followed by ecotoxicity.
