Waste Reduction Methods - AP Environmental Science
- Identify a benefit of upcycling.
- Reduces the need for raw materials. Conserves virgin materials by utilizing existing waste streams.
- What is the primary goal of waste reduction?
- To reduce the volume and toxicity of waste. Addresses both quantity and harmful properties of waste streams.
- What is the waste hierarchy?
- A ranking of waste management options by environmental impact. Prioritizes prevention, reuse, recycling, and disposal in order.
- What is the role of government in waste reduction?
- Regulating and incentivizing reduction practices. Creates policies and enforcement mechanisms for waste reduction.
- Identify a method to reduce paper waste.
- Using digital documents. Electronic alternatives eliminate physical paper consumption.
- Name a waste reduction method in agriculture.
- Crop rotation. Maintains soil health while reducing synthetic fertilizer waste.
- Identify a disadvantage of landfill use.
- Potential for groundwater contamination. Leachate from landfills can pollute underground water sources.
- What is 'precycling'?
- Choosing products with minimal packaging to reduce waste. Consumer decisions made before purchase to minimize future waste.
- What is composting?
- Decomposing organic waste into soil conditioner. Biological process that creates valuable soil amendment from organic waste.
- List a benefit of waste reduction.
- Conservation of natural resources. Reduces extraction pressure on natural ecosystems and raw materials.
- Identify a common household waste reduction practice.
- Composting kitchen scraps. Diverts organic waste from landfills into useful soil amendment.
- What is the purpose of a waste management plan?
- To outline strategies for handling waste effectively. Systematic approach coordinates reduction, reuse, and disposal activities.
- What is the purpose of a material recovery facility?
- Sorting and processing recyclables. Separates recyclables for reprocessing into new materials.
- Which material is commonly downcycled?
- Plastic. Recycling into lower-quality products due to material degradation.
- Which type of waste is most beneficial to compost?
- Organic waste. High carbon content decomposes efficiently into valuable compost.
- Which process converts waste to energy?
- Incineration. Thermal treatment generates electricity while reducing waste volume.
- What is a common use for recycled glass?
- Making new glass containers. Glass recycling maintains material quality through multiple cycles.
- Identify a cultural factor affecting waste production.
- Consumerism. Cultural emphasis on acquisition increases overall waste generation.
- Which international agreement focuses on waste management?
- The Basel Convention. Controls international movement of hazardous waste materials.
- What is the definition of waste reduction?
- Minimizing waste generation at the source. Prevents waste from being created rather than managing it after production.
- What is e-waste?
- Discarded electronic devices and components. Contains toxic materials requiring specialized disposal methods.
- Name a policy tool for encouraging waste reduction.
- Pay-as-you-throw programs. Economic incentive where waste generation costs increase with volume.
- Identify a key challenge in waste reduction.
- Lack of consumer awareness. Education gaps limit participation in reduction programs.
- Identify a benefit of employing recycling.
- Reduction in landfill use. Diverts materials from landfills, extending their operational lifespan.
- Name an advantage of a circular economy.
- Increased resource efficiency. Maximizes material value while minimizing resource extraction needs.
- What is 'waste diversion'?
- Redirecting waste from landfills to recycling. Channels waste toward beneficial uses instead of disposal.
- Identify a benefit of reducing industrial waste.
- Lower production costs. Less material input reduces manufacturing expenses and resource costs.
- What is a waste audit?
- An examination of waste stream to identify reduction opportunities. Analyzes waste composition to target specific reduction strategies.
- What does 'upcycling' mean?
- Converting waste into new materials or products. Creates higher-value products from waste materials than original.
- Which waste reduction method involves reusing materials?
- Recycling. Recycling processes used materials into new products instead of disposal.
- What is a circular economy?
- An economic system aimed at eliminating waste. Materials continuously cycle through production without becoming waste.
- Which strategy involves using products multiple times?
- Reuse. Extends product lifespan without reprocessing into new materials.
- What is the environmental impact of plastic waste?
- Pollution of oceans and harm to marine life. Persistent plastic accumulates in ecosystems, harming wildlife.
- Name a strategy for reducing food waste.
- Meal planning. Advance planning reduces overbuying and subsequent food disposal.
- Identify a method of source reduction in manufacturing.
- Redesigning products to use fewer resources. Source reduction focuses on using fewer materials during manufacturing.
- Identify a practice to reduce e-waste.
- Refurbishing old electronics. Extends electronic lifespan rather than immediate replacement.
