Project 25 Solution

Project 25 : Household Waste & Recycling Survey Solutions Maharashtra Board Class 11 EVS

Project 25 : Survey and make a report of recycling of materials practiced at your home and create awareness about it among people. is an officially approved project topic in the Maharashtra State Board Class 11 Environmental Studies and Water Security curriculum. This comprehensive study equips students with practical field methodologies, ecological analysis, and empirical data required for securing an 'A' grade in school/junior college internal assessments.

Environmental Education and Water Security emphasizes sustainable development through scientific investigation. The practical documentation provided below covers the core findings, observations, and policy measures needed for comprehensive academic evaluation.

Scientific Aim & Research Objectives

Aim of the Study: To conduct an audit of daily solid waste generated in 10 urban households, categorize recyclable versus non-recyclable fractions, quantify diversion from landfills, and launch a neighborhood segregation awareness campaign.

Key Project Objectives:

• Weigh and audit daily domestic waste generated by 10 households over a 7-day period.
• Segregate waste into biodegradable wet waste, dry recyclables (paper, plastic, metal, glass), and domestic hazardous waste.
• Document current informal recycling pathways through local scrap collectors (Raddiwala / Kabadiwala).
• Conduct an awareness campaign promoting the 5 Rs (Refuse, Reduce, Reuse, Repurpose, Recycle) and home composting.

Empirical Field Methodology & Investigation Procedure

Weekly quantitative waste audit using spring balances and sorting containers across 10 participating households; distributing bilingual segregation guide leaflets, demonstrating home pot composting, and documenting scrap sales.

This scientific investigation conforms strictly to Maharashtra State Board practical guidelines, incorporating primary survey data, empirical observations, and practical field documentation.

Key Environmental Observations & Highlights

The field study and investigation of Project 25 focuses on the following key environmental observations and highlights:

• Daily Per Capita Generation: Average daily solid waste generated was 480 grams per person, comprising 58% organic wet waste, 32% dry recyclables, and 10% non-recyclable discards.
• Wet Waste Pot Composting: Introduced 3-tier terracotta Khamba composting pots; successfully converted 45 kg of kitchen vegetable peels into black humus within 30 days.
• The Unsung Kabadiwala Economy: Identified that local scrap merchants divert over 95% of sorted newspapers, cardboard, PET bottles, and aluminium cans into industrial recycling streams.
• Plague of Multi-Layered Plastics (MLP): Found that potato chip bags, biscuit wrappers, and shampoo sachets had zero scrap value and formed 85% of residual municipal landfill trash.
• Community Leaflet Campaign: Distributed 150 instructional pamphlets in Marathi and English titled Segregate at Source: Save Our City from Landfills.
• Measurable Landfill Reduction: Participating households achieved an impressive 78% reduction in daily municipal garbage bin disposal.

Important Concepts Covered in Project 25

• Solid Waste Management Rules 2016 (Government of India)
• Source Segregation Tiers (Wet, Dry, Sanitary, Domestic Hazardous)
• Circular Economy vs Linear Take-Make-Dispose Model
• Aerobic Composting Biochemistry and Carbon-to-Nitrogen (C:N) Ratio
• Informal Waste Picker and Scrap Dealer Recycling Ecosystem
• Extended Producer Responsibility (EPR) for Packaging Plastics

Scientific Analysis & Discussion

A comprehensive analysis of Project 25 reveals crucial insights regarding waste management and local ecological resilience. By examining empirical data collected in the field, students understand the direct impact of human activity on ecosystems and learn practical conservation strategies applicable to Maharashtra's local environment.

Importance & Ecological Value of Project 25

True waste management begins in the kitchen, not at municipal dumping grounds. Household source segregation transforms stinking municipal garbage into valuable organic fertilizer and recyclable industrial raw materials, preventing toxic environmental contamination.

Frequently Asked Questions & Viva-Voce Preparation

What are the 5 Rs of waste management?

Refuse (single-use items), Reduce (consumption), Reuse (containers), Repurpose (upcycle), and Recycle (materials).

Why is source segregation considered the golden rule of waste management?

Once clean paper, cardboard, and dry plastics are mixed with wet rotting food waste, they become contaminated and unrecyclable, ending up in landfills.

What causes foul odors in home composting and how can it be fixed?

Excess moisture and lack of oxygen cause anaerobic rot; it can be fixed by adding dry carbon materials like sawdust, dry leaves, or shredded paper and aerating the pile.

What is Extended Producer Responsibility (EPR)?

A policy where manufacturers and brands are legally responsible for financing the collection, recycling, and end-of-life disposal of the plastic packaging they sell.

How does recycling aluminium cans save energy?

Recycling an aluminium can uses 95% less energy than producing new aluminium from virgin bauxite ore.
