摘要

The global community faces an energy crisis and environmental issues, which are exacerbated by the use of biomass in traditional cookstoves (TCS), particularly in rural and slum areas. TCS inefficiently burn biomass, emitting harmful pollutants and carbon, posing health and environmental risks. Elemental analysis of PM10 and PM2.5 was conducted using inductively coupled plasma mass spectrometry (5110 ICP-OES) to assess inhalation risks. Evaluating carbon emission reduction and cost-benefit analysis for transitioning to improved cook stoves (ICS) involved site surveys, interviews, questionnaires, and the Verified Carbon Standard (VCS) methodology from the CDM and UNFCCC. Results showed higher PM concentrations with TCS, emphasising varied health implications. Transitioning to ICS, particularly the locally manufactured rocket biomass model, could save 0.139 tonnes of fuelwood per capita annually, resulting in a reduction of 0.27380 tonnes of CO2 equivalent per person per year. TCS incur a higher operational fuel cost of 237,952 PKR/year and requires an annual wood consumption of 3536 kg. In contrast, the Rocket Biomass Cook stove has a reduced overall fuel cost of 153,709 PKR/year and an annual wood consumption of 2279.8 kg. Moreover, the Rocket Biomass Cook stove consistently demonstrates a lower NPV over the 5-year project life cycle compared to TCS. These findings underscore the economic and environmental benefits of transitioning from TCS to ICS, emphasizing significant fuelwood savings and reduced carbon emissions.
