| Parameter | IS Value | International | Source |
|---|---|---|---|
| Landfill Liner System | Recommends an 'impervious clayey soil' layer of about 60 cm. | Mandates a composite liner: a ≥1.5 mm HDPE geomembrane over a ≥60 cm compacted clay layer (k ≤ 1x10⁻⁷ cm/s). | 40 CFR Part 258 |
| Daily Cover at Landfill | Recommends 15 cm of earth cover at the end of each day's operation. | Mandates 15 cm (6 inches) of earthen material; alternative materials can be used if they control disease vectors, fires, odors, etc. | 40 CFR Part 258 |
| Waste Hierarchy Principle | Not formally defined; focuses on collection and disposal with some mention of processing. | Legally mandated 5-step hierarchy: 1. Prevention, 2. Preparing for re-use, 3. Recycling, 4. Other recovery (e.g. energy), 5. Disposal. | Directive 2008/98/EC |
| Landfill Gas Management | Recommends simple passive gas venting trenches filled with stones. | Requires an active gas collection and control system (e.g., flaring or energy recovery) for large landfills. | 40 CFR Part 258 |
| Leachate Management | Recommends collection drains but lacks detailed specifications for treatment. | Mandates a leachate collection system above the liner and requires collected leachate to be treated to meet environmental standards. | 40 CFR Part 258 |
| Responsibility for Waste | Implied to be a municipal responsibility. | Shared responsibility, including 'Extended Producer Responsibility' (EPR) for certain waste streams like packaging, electronics, and batteries. | Directive 2008/98/EC |
| Collection Frequency (Residential) | Recommends daily collection from households/bins. | Varies by stream; typically weekly for putrescible waste and bi-weekly for dry recyclables. | General EU/UK Practice |
