This study explores the socioeconomic impacts of recycling in Rio de Janeiro, demonstrating its economic feasibility and social benefits through greenhouse gas reduction and energy savings. The research highlights how recycled materials re-enter production, decreasing reliance on virgin resources.

Area of Science:

  • Environmental Economics
  • Waste Management Science
  • Socioeconomic Analysis

Background:

  • Solid waste management presents significant socioeconomic challenges in urban areas.
  • Recycling is a key component of sustainable waste management, but its economic and social impacts require detailed analysis.
  • Understanding the reintegration of recycled materials into the economy is crucial for resource efficiency.

Purpose of the Study:

  • To analyze the socioeconomic aspects of solid waste management in Rio de Janeiro.
  • To evaluate the economic feasibility and social benefits of recycling within the state.
  • To quantify the environmental impacts, including energy savings and greenhouse gas emission reductions, associated with recycling.

Main Methods:

  • Utilized an input-output methodology to model the reintroduction of secondary products from recycling into the productive process.

Related Experiment Videos

  • Developed a comparative profile of recycling against other solid waste management strategies.
  • Analyzed greenhouse gas emissions and energy consumption data specific to the State of Rio de Janeiro's input-output matrix.

    • Main Results:

    • Recycling demonstrates economic feasibility and provides social benefits within Rio de Janeiro's waste management system.
    • The reintroduction of recycled raw materials reduces the demand for virgin raw materials.
    • Significant energy savings and reductions in greenhouse gas emissions were quantified.

    Conclusions:

    • Recycling is an economically viable and socially beneficial strategy for solid waste management in Rio de Janeiro.
    • The integration of recycled materials into the production cycle contributes to resource conservation and environmental protection.
    • The study provides a quantitative basis for promoting recycling initiatives and policies in the region.
