3. OUTLINE Introduction Review of Existing Direct Analysis Studies in other Countries Direct Analysis Approach Waste Categories Sampling and Measurement Methods Data Analysis and Reporting 3

4. Introduction Waste Generation and landfilled in Mauritius - An acute problem 4 The process of collecting, treating, and disposing of waste materials. Importance: Ensures environmental protection, public health, and resource conservation.

5. Introduction The paramount requirement of waste characterisation Helps in planning recycling and composting programs by identifying the amounts of recyclables and organic material Helps in estimating waste transportation and separation costs using estimates of total municipal waste volume and weight Aids in sizing of WTE facilities based on the amount of wastes remaining in the waste stream after recycling and composting 5

6. Direct Analysis as Types of Waste in other countries Direct analysis in UK for residential waste compositions Aim of this study: Provide data that shall identify and implement waste diversion efforts Test the effectiveness of public education program Estimate the environmental impacts of solid waste system 6 Municipal Waste: Household and urban waste. Hazardous Waste: Industrial chemicals, batteries. Medical Waste: Hospital and biomedical waste. E-Waste: Old electronics and gadgets.

7. Direct Analysis as a waste characterisation approach in other countries Direct analysis in St Lucia This study focused on the composition of Municipal Solid Waste at 2 different landfills sites The St Lucia Authority aims to divert around 70% of waste according to the data obtained by the survey 7 Source: Waste characterisation Study, 2002

8. Direct Analysis Approach 8 Advantages Disadvantages Most common method of waste characterisation Time-consuming Can accurately determine amount of each waste category More applicable on small scale Expensive on national scale Source: Moore et al. 2014; Mirakovski et al. 2009

9. Methods of Waste Management 9 Landfills: Common but environmentally harmful. Incineration: Reduces volume but produces emissions. Recycling: Converts waste into reusable materials. Composting: Organic waste turned into fertilizer.

10. Recycling: A Key Practice 10 Perform Waste Sampling Sample selection needs to be random process : Collection, sorting, processing into new products. Benefits: Saves energy, reduces landfill, conserves natural resources.

11. C omposting Systems Composting is the biological decomposition of organic waste into nutrient-rich humus through controlled aerobic processes. There are various types of composting systems, including backyard/on-site, windrow composting, in-vessel composting, and vermicomposting. These systems help reduce landfill burden, recycle nutrients, and promote sustainability by enhancing carbon sequestration, reducing waste transport, and supporting a circular economy.

12. Waste-to-Energy (WTE) Methods Waste-to-Energy (WTE) methods are technologies that process waste to generate energy, such as electricity, heat, or fuel, while minimizing environmental impact. Two common WTE methods are incineration and biogas production . Explanation of WTE methods like incineration and biogas production.

13. Landfill Technologies Modern landfill technologies are designed to manage solid waste while minimizing environmental impact, improving efficiency, and protecting public health. Unlike traditional landfills, modern systems incorporate advanced engineering and environmental safeguards to address issues such as groundwater contamination, methane emissions, and land use. Overview of modern landfill technologies and their environmental impact.

14. Digital and Smart Systems Discussion of IoT, AI, and data-driven waste management solutions. The integration of IoT, AI, and data-driven waste management solutions has revolutionized the industry. IoT sensors monitor waste bins' fill levels, temperature, and weight in real-time, enabling smart bins to notify waste collection teams when they are nearly full. AI-powered robots sort recyclable materials automatically, and predictive analytics forecast waste generation patterns based on historical data. AI integrates with IoT to prioritize collection routes and identify operational inefficiencies.

15. Emerging Innovations Highlights of emerging technologies like plasma gasification and pyrolysis.
