1. Smart Indoor Decomposer unit to transport kitchen waste into fertilizer. GROUP NO:B07 MEMBERS OF GROUP: 1) SHREYA SHINDE. 2)SHARMEEN SHAIKH. 3)VAISHNAVI DOKE. Name of guide:MS.s.d.pujari. Name of Co-Guide: A.P.Kene . Department of electronics and telecommunication engineering

2. INTRODUCTION Smart Indoor Decomposer Unit: An innovative solution designed to transform kitchen waste into nutrient-rich fertilizer effortlessly. This cutting-edge appliance integrates seamlessly into your kitchen environment, providing an eco-friendly way to manage organic waste while reducing your carbon footprint . The Smart Indoor Decomposer Unit utilizes advanced composting technology to break down food scraps, including fruits, vegetables, coffee grounds, and more, into high-quality compost. Unlike traditional composting methods, this unit operates indoors with minimal odor and noise, making it ideal for urban dwellers or those with limited outdoor space. Equipped with smart sensors the unit monitors moisture levels, temperature, and microbial activity to optimize the decomposition process. Using powder like Tricoderma it ensure that your kitchen waste is transformed into compost efficiently, typically within a few weeks.

4. Objectives of Research Efficient Waste Decomposition Objective : Accelerate the natural decomposition process of organic kitchen waste, converting it into nutrient-rich fertilizer in a shorter time frame compared to traditional composting methods. Outcome : Produce high-quality compost within weeks, rather than months, optimizing the use of kitchen waste. User-Friendly Operation Objective : Provide an intuitive and easy-to-use system that requires minimal user intervention. Outcome : Design a unit with automated processes, clear instructions, and simple controls, allowing users to effortlessly manage their kitchen waste and compost production. Environmental Sustainability Objective : Reduce the amount of organic waste sent to landfills, lowering greenhouse gas emissions and promoting eco-friendly waste management practices. Outcome : Encourage sustainable living by providing a practical solution for reducing household waste and recycling it into valuable fertilizer

5. Literature Review Name of Author Methodology Gap Identified Zhou Chen (Jan 2023) High moisture content in KW results in the generation of significant leachate (kitchen waste composting leachate (KWCL)) during the composting process. It has posed a potential risk of groundwater pollution and can have a severe environmental impact  Shenghua Zhang (Aug 2023) Demonstrated that KWL was a more suitable liquid supplement than KWCL. It ensured proper compost maturation and effectively mitigated N 2 O emissions. Bacterial and fungal communities exhibited higher diversity and abundance in the CK, with the fungal community showing lower diversity and abundance than the bacterial W. Wang (2024) construct a novel object detection method named KWDet for the automatic detection of kitchen waste. In this only same type of waste can be accepted by the model.

6. Gaps Identified from Literature. Inspiration Gaps KWL is more suitable as a liquid supplement offers a path forward. KWL appears to ensure proper compost maturation, likely by maintaining a balanced nutrient profile and moisture content, and effectively mitigating harmful N₂O emissions. KWCL generated from high-moisture kitchen waste during composting, may not be ideal as a liquid supplement. This could be due to its potential to negatively impact the composting process or contribute to environmental issues like increased nitrogen emissions, particularly N₂O. Development of optimized composting processes that prioritize the use of KWL over KWCL. This might involve refining the pre-composting treatment of kitchen waste to generate KWL or directly utilizing KWL as a supplement in composting systems. KWCL might hinder proper compost maturation, possibly due to imbalances in nutrients or the introduction of excess moisture and organic acids that could slow down or disrupt the composting process. The ability of KWL to mitigate N₂O emissions could lead to more sustainable composting practices, reducing the environmental impact of waste management processes. The use of KWCL could lead to increased emissions of greenhouse gases like nitrous oxide (N₂O), which is a potent contributor to climate change. This underscores the need for a more environmentally friendly alternative.
