15.1 Environmental Issues

Environmental Issues in Design and Manufacture

The Consumer Society

• Components interlinking the consumer society:

  • Mass production

  • Increased choice: Leads to more products available to consumers.

  • Consumer demand: The desire for new products fuels production.

  • Throw-away mentality: Societal tendency to discard rather than recycle or reuse products.

Sustainability

• Resource Consumption:

  • Since the 1970s, humanity has consumed more resources than the Earth can replenish.

• To develop sustainably, one must:

  • Rethink and regulate consumption: Evaluating current usage patterns.

  • Develop more sustainable practices: Emphasizing eco-friendly design and manufacturing.

  • Ensure future generations' needs are met: Focus on resource longevity.

• Role of Designers:

  • Designers can minimize environmental impact through eco-conscious design choices.

Designing the Future

• Focus Areas for Designers and Manufacturers

  • Environmental sustainability: Minimizing ecological impacts.

  • Economic sustainability: Ensuring the products are viable in the long term.

  • Social sustainability: Addressing community and social aspects.

• Impact of Increased Life Expectancy:

  • The design of products that cater to an aging population may change social sustainability dimensions.

Carbon Footprint

• Definition of Carbon Footprint:

  • A measurable impact of greenhouse gas emissions quantified from:

  • An individual.

  • A company.

  • A country.

• Calculation of Personal Carbon Footprint:

  • Sum of all emissions caused by an individual’s activities over one year.

Carbon Footprint of Products

• Measuring Environmental Impact:

  • The carbon footprint of a product serves as an indicator of its ecological effects.

  • Ways to Reduce Carbon Footprint:

  • Designers can develop lower-emission products.

  • Consumer choices, such as opting for products with lower carbon footprints, significantly affect overall emissions.

Carbon Offsetting

• Concept of Carbon Offsetting:

  • To counterbalance CO2 emissions, strategies include:

  • Planting trees.

  • Using electric vehicles.

  • Choosing renewable energy sources.

  • Donating to environmental charities.

Environmental Perspectives

• Influencing Decisions:

  • Environmental considerations impact product design, development, and manufacturing that include:

  • Energy consumption and generation.

  • Material sourcing and use.

  • Waste disposal practices

Pollution and Emissions

• Sources of Environmental Pollutants:

  • Activities such as farming, extraction, processing, and manufacturing contribute to emissions of:

  • Carbon dioxide (CO2).

  • Carbon monoxide (CO).

  • Nitrogen oxides (NOx).

  • Methane (CH4) and Volatile Organic Compounds (VOCs).

  • Particulates.

  • Petrochemicals and Biochemicals.

Deforestation

• Deforestation Facts:

  • Trees are renewable but are being harvested faster than they can regrow.

  • Forests function as carbon sinks and produce oxygen.

  • Deforestation accounts for 15% of total greenhouse gas emissions.

  • Consequences include

  • Displacement of communities.

  • Loss of crucial habitats.

  • Soil erosion leading to flooding.

Climate Change

• Far-reaching Effects on Ecosystems:

  • Includes phenomena such as:

  • Melting sea ice and glaciers.

  • Rising sea levels.

  • Desertification leading to habitat loss.

  • Increased frequency of extreme weather conditions.

Prolific Plastics

• Impact of Discarded Products:

  • Waste plastic has emerged as a significant environmental issue.

  • Usage of plastic has increased rapidly due to its affordability and resistance to degradation.

  • UK Plastic Consumption:

  • Over 5 million tonnes of plastic are used each year in the UK.

The Scale of the Problem

• Environmental Research Findings:

  • Studies indicate that approximately 40% of the world’s oceans exhibit patches of plastic waste.

  • Around 300 species, including seals and turtles, suffer from entanglement or ingestion of plastic waste.

  • Microplastics: They serve as carriers for other toxic compounds, resulting in further environmental damage.

Single Use Plastic

• Focus on Single-Use Plastics:

  • Single-use products represent about 20% of all litter.

  • Impact of Legislation:

  • In England, the introduction of a 5p charge on plastic bags resulted in a significant decline in their use.

  • Norway's deposit-return schemes achieved 96% return rates for plastic bottles.

  • Government Initiatives:

  • The UK is considering new recycling schemes and potential taxes on plastic packaging.
