Abstract There is no clear direction in the management of electrical and electronic waste products (e-waste), as there are no regulations on ways to do so. This research attempts to understand the trade-off between economic value and environmental effects of the current disposal of e-waste to find ways to optimize waste management, focusing on cellphones, television CRTs, desktop computers, and air conditioners. A Life Cycle Assessment (LCA) is a tool that can analyze various influences, e.g., environmental, costs, and value added. Under the e-waste management status quo, most household e-wastes are kept in houses because owners do not know where to discard them. In addition, informal sectors, such as domestic farmers or workers, have been involved actively for more than a decade, leading to poor management standards for both health and the environment. The logistics are inefficient because the dismantling communities and recycling industry are far apart. Most e-waste is generated, and most recycling industries are located, in the Central region (the richest areas), while the dismantling communities are located in the Northeastern region (the poorest areas). Further, LCA and LCC of e-waste are sensitive to transportation, and not all e-waste parts can be recycled within the country. High-tech mineral extraction cannot be practiced in the country, and thus, circuit boards and batteries are exported for recycling. To promote a circular economy, e-waste management regulations should be implemented and a full recycling industry should be established in the country.

Environmental Assessments

The eco-efficiency can be defined by using the “economic value/environmental impacts” ratio. In this study the eco-efficiency of orange production in the Comunidad Valenciana was assessed. 24 scenarios of orange production were built regarding their agricultural practices. For every scenario the environmental impacts were assessed by means of Life Cycle Assessment (LCA) as well as the economic value added. The results have been referred to 1 kg oranges. The integration of the economic and environmental assessments was made through Data Envelopment Analysis (DEA). Among the scenarios scored as eco-efficient, those with organic production prevailed.

The United Nations Environment Program (UNEP) defines life cycle assessment is a tool that is used for systematic evaluation of the environmental aspects of either a product or service system in the entire stages of its lifecycle. In this research, second hand material research would be used to determine the current methods used for the disposal of the ELVs. Moreover, cost metrics will be used to determine the economic value of the network. This research will look into study background, the problem statement, hypothesis of the study, objectives of the study, literature review and methodology to outline possible research criteria to draw conclusion on the research topic. The research will be very resourceful to the scientific community because it will help to find the optimal location for the centralized processing facility that will minimize cost and avoid hazard in the environment. </span></p>

Garbage can be interpreted as a consequence of the activities of human life. It is undeniable, garbage will always be there as long as life activities continue to run. Every year, it can be ascertained that the volume of waste will always increase along with the increasing pattern of public consumerism. The landfill which is increasingly polluting the environment requires a technique and management to manage waste into something useful and of economic value, Bantas Village, Selemadeg Timur District, Tabanan Regency currently has a Waste Management Site (TPS3R) managed by Non-Governmental Organizations (KSM ) The source of waste comes from Households, Stalls, Restaurant Entrepreneurs, Schools, Offices and Ceremonies which are organic and inorganic waste. The waste management system at Bantas Lestari TPS with 3R system is Reduce (reduction of waste products starts from the source), Reuse (reuse for waste that can be reused) and Recycle (recycling waste) to date it is still running but not optimal. The method used in this research is descriptive quantitative with data analysis using SWOT analysis. This study produces a Waste Management Strategy which is the result of research from the management aspect, aspects of human resources and aspects of infrastructure facilities.

Pavement Structures

Rigid pavement structures are one of the costly components of the infrastructure development process. It consumes a huge quantity of ingredients necessary for concrete development. Hence, a newly introduced concept of circular economy in combination with waste management was introduced to solve this problem. In this study, three waste products (rice husk ash (RHA), wood sawdust (WSD), and processes waste tea (PWT)) was utilized to develop the concrete for rigid pavement structures by replacing the sand, i.e., a filler material at different percentages. During the testing procedure of compressive (CS), tensile (TS), and flexural strength (FS) properties, RHA and WSD at 5% replacement were found to be a good replacement of sand to develop required concrete. This study will help in the production of eco-friendly rigid pavement structures and a pathway of life cycle assessment in the future.

The environmental impacts of five waste management scenarios for polylactic acid (PLA)-based bioplastics and food waste were quantified using life cycle assessment. Laboratory experiments have demonstrated the potential for a pretreatment process to accelerate the degradation of bioplastics and were modeled in two of the five scenarios assessed. The five scenarios analyzed in this study were: (1a) Anaerobic digestion (1b) Anaerobic digestion with pretreatment; (2a) Compost; (2a) Compost with pretreatment; (3) Landfill. Results suggested that food waste and pretreated bioplastics disposed of with an anaerobic digester offers life cycle and environmental net total benefits (environmental advantages/offsets) in several areas: ecotoxicity (−81.38 CTUe), eutrophication (0 kg N eq), cumulative energy demand (−1.79 MJ), global warming potential (0.19 kg CO2), and human health non-carcinogenic (−2.52 CTuh). Normalized results across all impact categories show that anaerobically digesting food waste and bioplastics offer the most offsets for ecotoxicity, eutrophication, cumulative energy demand and non-carcinogenic. Implications from this study can lead to nutrient and energy recovery from an anaerobic digester that can diversify the types of fertilizers and decrease landfill waste while decreasing dependency on non-renewable technologies. Thus, using anaerobic digestion to manage bioplastics and food waste should be further explored as a viable and sustainable solution for waste management.
