Speech Title: Design and Construction of Hybrid Solar Farm Cooler for Preservation of Farm Perishables

Abstract: During the calendar year 2023 alone, the volume of Tomato production in India was estimated to have amounted to over 20 million metric tons. However, in India, due to a lack of proper storage and transportation facilities, about 20-40% of tomatoes are wasted (Statista Inc. Aug 24, 2023). Similarly India's flower production was estimated to amount to nearly 3 million metric tons in the year 2023. Here also the wastage was around 30-40% (Statista Inc. Aug 24, 2023) due to the same reasons. This research work aims to preserve and extend the shelf life of farm produce like Tomato, flowers, vegetables and other perishables when they are abundant but market price is lower. To achieve this, a Hybrid cold storage is built in the farm itself by running a Solar operated DC Inverter Vapour Compression Refrigeration system inside the red brick-sand structure which reduces the heat load on the storage unit by Evaporative cooling. As air in tropical regions are of lesser in humidity, the air flowing over the brick and sand structure continuously carry away the water vapour from the surface of the brick wall, which is permeable to water, which in return is poured periodically from the top of the wall gaps to achieve the optimum DBT and RH in the storage space. To achieve maximum permeability and hence the evaporation rate the gap between the inner and outer brick walls are filled with coarse river sand of permeability 1- 0.1×10-3ms-1. Generally, the ripened tomatoes can be stored in this type of cold storage for up to 2 to3 weeks at a temperature of 12°C- 16°C with a relative humidity of 85-90%. This results in significant reduction of wastage and also remunerative prices for farmers, when the market price is better. Thereby we can save about 9000 million Indian Rupees (112.5 million USD) per year as of 2023 Statistics when we take average Tomato price Rupees. 15.00 / kg results in significant saving of 0.01 % on India’s GDP( 1720 Lakh millions Rupees as of 2023-2024, National Statistical Office (NSO, India,12-04-2024).

Speech Title: Environmental Impact of Nuclear Plant: Exemplified in the Anti-Nuclear Movement in Taiwan

Abstract: This paper explores the dynamics between nuclear plants, political parties, and anti-nuclear movements in Taiwan. By analyzing the development of anti-nuclear movements in Taiwan, this research highlights the complex role of political parties in the anti-nuclear movements. The environmental impact of nuclear power plants is a multifaceted issue that involves considerations ranging from emissions to waste management and potential accidents. Consequently, politics plays a significant role in shaping the environmental impact of nuclear power. The politicization of anti-nuclear energy in Taiwan is a complex and multifaceted issue. Taiwan has experienced significant debate and division over the role of nuclear energy in its overall energy strategy. One major factor contributing to the resurgence of anti-nuclear power in Taiwan is the Fukushima Daiichi nuclear disaster in 2011. This event heightened public concerns about the safety of nuclear power, leading to increased opposition to nuclear energy and calls for its phase-out. Furthermore, Taiwan's unique political landscape, with its own domestic and international pressures, has also contributed to the politicization of this issue. In recent years, the Taiwanese government has navigated this complex landscape by outlining plans to gradually reduce its reliance on nuclear power while increasing investments in renewable energy sources. However, the issue remains politically charged and continues to be a subject of ongoing debate and activism. Overall, the politicization of anti-nuclear energy in Taiwan reflects larger societal concerns about environmental safety, energy independence, and the balance between economic development and sustainable practices.

Speech Title: Application of NMR spectroscopy on characterization of phosphorus speciation in sewage sludge

Abstract: Sewage sludge is a promising resource for the recovery of phosphorus (P), an essential nutrient for agricultural production but with finite phosphate rock reserves. To select the optimal P recovery practice, it is imperative to understand the detailed P speciation in sewage sludge. In this study, advanced liquid- and solid-state NMR spectroscopy were used in combination with conventional analytical techniques (e.g., powder X-ray diffraction, scanning electron microscopy, and sequential P extraction) to elucidate the P speciation in the sludge throughout three municipal wastewater treatment plants (WWTPs). Liquid-state 31P NMR analysis showed that organophosphate (organic-P, 37-45%) and inorganic orthophosphate (ortho-P, 53-61%) dominated in the primary sludge; a significant amount of polyphosphate (poly-P, 23-44%) was formed in the secondary sludge due to the function of poly-P accumulating organisms (PAOs). After anaerobic digestion, inorganic ortho-P became the dominant P species (90-95%) in the sludge since most poly-P and organic-P were hydrolysed. This variation of P speciation throughout the WWTPs was consistent with the solid-state 31P NMR analysis. Moreover, solid-state 27Al NMR spectra of the sludge after Al-based chemical P removal revealed that the Al-bound P existed in the form of phosphate adsorbed on Al (hydr)oxides. The NMR spectroscopy provides important information for P speciation in the sewage sludge, and this will facilitate the implementation of optimal P recovery technology in WWTPs.
