The hierarchy of waste refers to the “3 Rs” i.e. Reduce, Reuse and Recycle, which implements the strategies of waste management according to their specifications in terms of waste minimisation. The power of solar was exposed to people when Jawaharlal Nehru National Solar Mission (JNNSM) was introduced in the country in the year 2010.From then on people started to install and set up the solar as they came to know that the end life of it is around to be 2035. But none of them thought about future, i.e. what would happen to the solar panels when they are not able to generate power. Now the main issue is how will India be able to discard nearly 90 GW worth solar panel in the next 20 years? Where an average solar panel sized 250 watts, 90GW will amount to almost 7.7 million tonnes of E- waste at the end of a lifetime of a solar plant [1]. This paper mainly focuses on how these E-wastes produced can be reused and recycled.

Water Cooling System

Sun-oriented energy is a resource of energy on earth. Sun-based energy can be gotten as warmth to create power or it is additionally conceivable to change over sun-based energy straightforwardly into power. The main objective of this project is to catch maximum solar radiation from the sun and increase the overall efficiency of solar panels. To design a cleaning mechanism that runs across the length of the panel. To avoid dust-associated problems on the solar panels. The temperature in case of water cooling system was lowered down to 410C from the ambient temperature 440C at 14:00 in the morning of 21/09/2020. The power output was 4.789W and in case of set up having dust on the surface of the solar panel the temperature rose to 490C with power reduced to 4.00185W. The temperature in case of water cooling system was lowered down to 400C from the ambient temperature 430C at 14:00 in the morning of 22/09/2020. The power output was 4.89W and in case of set up having dust on the surface of the solar panel the temperature rose to 490C with power reduced to 4.00185W. The outcomes for day 3 of the experimentation were also recorded on 23/09/2020 and the setup with a cooling system produces a maximum power of 5.20 W by lowering the temperature to 370C from the maximum ambient temperature of the day 410C

Waste Classification

The use of hazardous metals like lead, cadmium in solar photovoltaics (PVs) are rapidly increasing which poses the risk to the environment due to potential release of these constituents. The main purpose of this review is to highlight the updated information on solar PV waste along with the present condition of efforts for recovery, country-wise regulatory approach or strategy on solar PV management and recycling. A brief literature review is assessed based on recently published articles and reports, which provides the readers a general overview on the solar PV waste management and regulations made by world leader countries in solar panels. This study discussed on the risk of hazardous chemical species releasing from PV modules and criteria of PV panel waste classification. Furthermore, the estimation of solar waste PV, its categorization, management approaches, country guidelines and recycling of waste PV panels, were mainly focused in this study. Apart from this, the major leaching tests carried out for waste classification and PV waste recycling in different countries are also discussed. Solar PV waste generally categorized as a general waste by the regulatory aspect, except in the EU, since PV panels in these countries are described as e-waste as stated in the Waste Electrical and Electronic Equipment (WEEE) Directive. To reinforce the recycling option, currently only Europe has mandated a strong regulatory guideline, however, other nations are preparing to set up particular system for solar panel waste management. In particular, this paper focuses on the potential risk caused by solar panels, data collection for PV waste and management approach like recycling. Besides, this review believes the basics of PV panel installation, management and recycling process which could recommend upcoming guidance for the public policymakers.

Phase Out

Nuclear phase-out policies and the European obligation to liberalise electricity markets could put the French nuclear option dramatically at risk by influencing social preferences or by constraining power producers' investment choices in the future. So far, the particular institutional set-up which has allowed the efficient build-up and operation of several series of standardised reactors preserves the stability of the main elements of the option. However, important adaptations to the evolving industrial and political environment occur and contribute to changing the option. Some institutional changes (such as local public inquiry, creation of a Parliamentary committee, independence of safety authorities) and divergence between industrial interests already allow debates on internal options such as reprocessing, type of waste management deposits, ordering of an advanced PWR. These changes improve the cost transparency, even if internalisation of nuclear externalities (cost of insurance, provisions for waste management) is still incomplete. However, when effective, this internalisation would not affect definitively the competitive position of the nuclear production because of the parallel internalisation of CO2 externalities from fossil fuel power generation in the official rationale. Consequently the real issue for the future of the nuclear option in France remains the preservation of social acceptability in the perception of nuclear risks.

Waste Pickers

This article presents the informal recycling sector’s (IRS) social, economic driving factors in five cities in Indonesia and their contribution to waste management in the cities. An on-field analysis was conducted by random and incidental sampling method of questionnaire administration followed by observation. Among the respondents ( n = 178), 79% of individuals were waste pickers, 15% were small-scale waste collectors, and 6% were medium-scale waste collectors. The majority of the waste pickers sampled are male (79%). The amount of waste collected by individual waste pickers is 43.87 kg person−1 day−1, a corresponding recycling rate of approximately 12%, and an average monthly income of US$91.7. Gender differences are apparent as the male waste pickers generated higher incomes than those earned by their female counterparts (US$128.3 for men and US$69.7 for women) even as their average work hours are similar to that of the men (7.8 and 7.6 hours day−1, respectively). Economic motives are the respondents’ primary driving factors as moving to large cities accompanied by their family members. The study concluded that the IRS plays substantial contribution to waste management; further integrating them into the waste management system via IRS association, additional investment, formulation of law and policies and efforts by municipalities can give various benefits for involved stakeholders, the community and the environment. The results can serve as a significant reference for improving the solid waste recycling system and informal sector management in Indonesian cities and other developing countries.

The construction industry consumes a substantial amount of raw materials in its processes and the output is obviously the product and most importantly the waste material. Other than that, the construction industry is well known as one of the worst environmental polluters. This study is to determine the use of waste minimisation technique in creating sustainable waste management in order to identify the technique which has the most capabilities to reduce on-site waste. The objective of this study is to assess the waste minimization techniques taken from the 4R concept (which includes reduce, reuse, recycle and recovery techniques) in minimizing the waste in construction waste management. The most used waste minimization technique found in the 4R concept would be waste reduction. This shows that the local construction industry has the knowledge necessary to plan out the waste management processes but the implementation is still far from satisfying. Additionally, the findings reveal that because the industry is profit-driven, construction practitioners are motivated by profit to adapt to this techniques.

<div>We assessed several state-of-the-art deep learning algorithms and computer vision techniques for estimating the particle size of mixed commercial waste from images. In waste management, the first step is often coarse shredding, using the particle size to set up the shredder machine. The difficulty is separating the waste particles in an image, which can not be performed well. This work focused on estimating size by using the texture from the input image, captured at a fixed height from the camera lens to the ground. We found that EfficientNet achieved the best performance of 0.72 on F1-Score and 75.89% on accuracy.<br></div>

Discussion in the process of teaching refers to a more sophisticated form of conversation, which is more frequently applied working with senior school learners. Problems rather than facts or phenomena are discussed. The question rises if the method of discussion is relevant in lessons of surrounding world learn-ing and whether it enables school learners to acquire knowledge, facilitates its memorisation or allows to ar-rive at solutions to urgent problems. The research involved 18 second formers, 15 school learners of fourth form and 13 students. All the groups of respondents discussed the same problem. Different roles were assigned to the participants in the discussion (a number of respondents represented heads of waste management company, whereas the rest assumed roles of residents of area where waste dump was being set up) and they involved in discussions of issues related to waste management and waste dump establishment. A considerable difference in the results of questionnaires provided to the participants before and after the discussion was observed. It is obvious that the respondents not only gained knowledge but also acquired a different perception and understanding of the problems analysed in the discussion. However, the compari-son of all the results of the survey revealed a stronger educational role of the discussion teaching fourth for-mers. This confirms theoretical statements that this method is more effective with senior school learners. The group of students also found the discussion useful. Key words: primary education, teaching of surrounding world learning, teaching methods, discussion.

Module Performance

The use of renewable energy as a source of electrical energyincreases every year. Unfortunately, Indonesia does not have manypower plants that utilize renewable energy sources. The mostpotential renewable energy in Indonesia is the sunlight with the helpof solar panels that converts solar energy into electrical energy.However, the environment could affect the solar panel module andin turn, affect the performance of solar panels or the generatedelectric energy. This research calculated the performance of solarpanels with a single-diode model using the Five Parameters methodthat required solar panel module specification data, the totalradiation absorbed by the solar panel module, and the temperatureof the environment. The Five Parameters method is a methodmodeled after solar panel module performance in the form of thesingle-diode equivalent circuit. The Five Parameters method isreliable in predicting the energy produced by the solar panels whenthe input data is limited. The results for using the Five Parametersin monocrystalline solar panels were Isc = 1.827 A, Imp = 0.662 A,Voc = 18.221 V, Vmp = 15.019 V, Pmp = 9.955 W. And the results inpolycrystalline solar panels were Isc = 1.926 A, Imp = 0.686 A, Voc =17.594 V, Vmp = 14.166 V, Pmp = 9.722 W. Based on the results; itwas concluded that the most efficient and optimised types of solarpanels on natural conditions in Sendang Biru Beach was themonocrystalline solar panel because it produced electrical outputpower of 9.955 W. Therefore, there could be a manufacturer ofsolar energy power plants to reduce the cost of electricity in thecoastal area, such as in Sendang Biru Beach.
