Green ICT and E-Waste Management

Definition and Goals of Green ICT

• Green ICT: The study and practice of designing, manufacturing, using, and disposing of computers, servers, and subsystems (monitors, printers, storage) to reduce environmental harm.
• Core Objectives: Reduction of carbon footprint, encouraging a circular economy, prevention of pollution, chemical substances management, biodiversity conservation, and promoting energy efficiency.
• Life Cycle Management: Focuses on environmentally friendly practices from design through to disposal to save energy and protect nature.

Environmental Impact and Local Context

• Global Impact: ICT contributes approximately $4\%$ of global carbon emissions, with data centers consuming $1\%$ of global electricity.
• The Philippines: Generates over $700,000$ tons of e-waste annually and ranks as a top e-waste generator in Southeast Asia.
• Pollutants: Discarded electronics release toxic substances such as lead, mercury, and cadmium into soil and water.

Device Energy Consumption

Understanding power usage helps in making smarter choices to lower energy costs:

• Laptop: $\sim 50\,W$ average ($\approx 219\,kWh/year$ if on $12$ hours/day).
• Monitor: $20-80\,W$ ($\approx 88-350\,kWh/year$ if left on).
• Smartphone: $2-6\,W$ ($\approx 5-11\,kWh/year$ for daily charging).
• Printer: $30-500\,W$ ($3-5\,W$ on standby).

Sustainable Management and Practices

• E-Waste Management Strategies: Includes sustainable design for longevity, refurbishing and reuse, remanufacturing waste into new products, and responsible recycling to recover valuable materials.
• Responsible Habits:
  • Power down devices and unplug chargers when not in use.
  • Reduce screen brightness and use power-saving modes.
  • Stream in standard definition and delete unnecessary cloud files/emails.
  • Avoid unnecessary printing and prefer digital communication.
• Benefits: Practicing Green ICT can reduce household electricity bills by up to $30\%$.

ICT as Problem vs. Solution

• The Problem: High energy consumption, paper waste from excessive printing, and improper disposal of hazardous gadgets in landfills.
• The Solution: Paperless communication, digital attendance systems, online meetings (replacing travel), and using ICT tools for environmental monitoring.

Philippine Legal Framework for E-Waste

• RA 6969: The "Toxic Substances and Hazardous and Nuclear Waste Control Act of 1990" and its Implementing Rules (DENR Administrative Order No. 1992-29).
• Hazardous Classification: E-waste (WEEE) is legally classified as hazardous due to components like lead, mercury, and hexavalent chromium.
• Handling Requirements: Disposal must involve the Online Hazardous Waste Manifest System, DENR-accredited transporters, and TSD Facilities.
