Ï 2.1 Waste production Ë Renewable resourceResources naturally replenished within a human timescale. Ë Examples of renewable resources Sunlight Plantation timber Wind Water Waves Geothermal heat. Ë Inexhaustible renewables Wind Solar Tidal energies. Ë Wind powerEnergy generated from wind using turbines to convert kinetic energy into electricity. Ë Solar energyEnergy harnessed from sunlight using solar cells to generate electricity or heat water. Ë HydropowerElectricity generated using fast-moving water in rivers, harnessing its kinetic energy through turbines in dams. Ë Tidal energyEnergy generated by the movement of water caused by tides, using dams or turbines to convert kinetic energy into electricity. Ë Biomass & BiofuelBiological materials, such as wood and waste, converted into energy by burning or producing biofuels. Lifespan: At least 30 years. Ë Geothermal energyThermal energy from the Earth's interior, used for electricity or heating. Lifespan: 25 years. Ë CoalElectricity generated by burning coal in power stations, a major source of global electricity. Ë Natural gasElectricity produced by burning natural gas in power plants, generating about 1/4 of global electricity. Ë OilElectricity generated from burning oil, similar to coal and gas operations. Ë Nuclear energyEnergy from nuclear fission, known for high output and low emissions. Ë ReservesStocks of materials available, divided into proven reserves (economically recoverable) and probable reserves (with future potential). Proven reservesResources that can be extracted economically. Probable reservesResources not currently viable, like gold in seawater. Ë RenewabilityAbility of a resource to renew itself faster or at a rate equal to its consumption; excessive use can reduce renewability, as seen in water and deforestation. Depletion riskOveruse of renewable resources can lead to desertification and species extinction. PollutionPollution can make resources like water non-renewable in some areas. Ë Waste Mitigation StrategiesStrategies to reduce or eliminate landfill disposal volume. Ë Waste Mitigation Principles Re-use Recycle Repair Recondition Re-engineer Pollution/Waste reduction methodologies Dematerialization Product recovery strategies Circular economy: Using waste as a resource in a closed-loop system. Ë Circular EconomyKeeping resources in use as long as possible by regenerating products and materials, contrasting the linear economy of "make, use, dispose." Ë Re-use in Waste MitigationUsing a product multiple times in the same or different context, like glass bottles for storage. Ë Repair in Waste MitigationRenewing or reconstructing parts of existing products, such as mending clothes, though repair is often less common due to replacement cost-effectiveness. Ë Pollution/WasteProduction processes create pollution and waste from extraction to packaging, resulting in excess heat, exhaust, chemical discharges, and leftover packaging. Ë DematerializationUsing fewer materials and energy throughout a product's lifecycle, including lighter products and reducing disposal waste. Ï 2.2 Waste mitigation strategies Ë Waste mitigation strategiesReduce/eliminate landfill waste through reuse, recycling, and sustainable practices. Ë Re-useUsing a product multiple times without altering its structure, e.g., reusing glass bottles. Ë RecyclingConvert materials from waste into new products, reducing raw material use and pollution. Ë RepairRenew parts of an existing product, extending its life rather than discarding it. Ë Re-engineeringImprove products by adding new functions and tech, e.g., more efficient car aerodynamics. Ë Waste streamsAll waste generated during a products lifecycle; recycling reduces waste flow. Ë Pollution and wasteProduced during manufacturing, transportation, and disposal, causing environmental harm. Ë Waste management hierarchy Prevention Minimization Reuse Recycling Energy Recovery Disposal Ë DematerializationReduce material/energy in products by making them lighter or using eco-friendly alternatives. Ë ELV DirectiveRequires 95% of vehicle parts to be recovered or reused. Ë WEEE DirectiveManufacturers must set up recycling systems to reduce electronic waste in landfills.
