  • using Material Substance flow analysis to support sustainable development assessment a literature review and outlook
    Resources Conservation and Recycling, 2012
    Co-Authors: Chulong Huang, Jonathan Vause
    Abstract:

    Abstract The essence of sustainable development (SD) is to deliver social and economic development without compromising environmental quality. Material Flow Analysis or Substance Flow Analysis (M/SFA) is a well-established method to assess the sustainability of socioeconomic development and environmental change, particularly from the perspective of improving Material/Substance flow efficiency. A Material/Substance flow chart or accounting table makes SD assessment results comprehensive, comparable and verifiable by (1) providing systematic information and indicators for SD assessment, (2) identifying critical pathways, links and key Substances in the anthroposphere, and (3) allowing the dynamic interaction between Material flow and social, economic and/or environmental processes to be analyzed. However, the role of M/SFA in SD assessment could be expanded by strengthening simultaneous analysis of various features of Material/Substance flows, integrating M/SFA with other assessment methods, improving sustainability indicators, and further developing standardized methods for Material classification, data acquisition and processing, and measuring indirect flows and unused flows. It is anticipated that future improvements in monitoring Material/Substance flows in the anthroposphere will provide more systematic information, allowing M/SFA to play an even greater role in SD assessment.

  • Inventory and Substance flow analysis of polybrominated diphenyl ethers in the Nigerian transport sector—end-of-life vehicles policy and management
    Environmental Science and Pollution Research, 2018
    Co-Authors: J. O. Babayemi, O. Sindiku, Oladele Osibanjo, R Weber
    Abstract:

    Recently, certain polybrominated diphenyl ethers (PBDEs) have been listed as persistent organic pollutants (POPs) in the Stockholm Convention. In this study, a preliminary Material and Substance flow analysis of commercial pentabromodiphenyl ether (c-PentaBDE) was conducted for motor vehicles—a major use sector for POP-PBDE in polyurethane (PUR) foam—for Nigeria. The methodology of the Stockholm Convention PBDE inventory guidance was used for the calculation of c-PentaBDE. Material/Substance flow analysis was conducted applying the STAN software. The time frame for this analysis was 1980–2010, considering that this was the period when POP-PBDE-containing vehicles were largely imported into Nigeria. It is estimated that the approximately 19 million passenger cars imported from 1980 to 2010 contained ca. 270 t of POP-PBDEs in ca. 401,000 t of PUR foam. A major share of cars from the USA and only a small share of cars from Europe and Asia were impacted. This simplified Material and Substance flow of PUR foams and POP-PBDEs in motor vehicles demonstrated the potential for environmental/human contamination and pollution of recycling/reuse for Nigeria and other developing countries. The study developed the first preliminary inventory of end-of-life vehicles for Nigeria, following which the environment ministry has taken up the important issue of end-of-life vehicles management. Considering that a range of other pollutants are contained in vehicles (e.g. heavy metals, flame retardants, PCBs, chlorofluorocarbons, hydrofluorocarbons and waste oil), this initiated activity should finally lead to an integrated management of pollutants and resources from the transport sector.

  • Substance flow analysis of polybrominated diphenyl ethers in plastic from eee weee in nigeria in the frame of stockholm convention as a basis for policy advice
    Environmental Science and Pollution Research, 2015
    Co-Authors: J. O. Babayemi, O. Sindiku, Oladele Osibanjo, Roland Weber
    Abstract:

    This study investigated the Material/Substance flow of polybrominated diphenyl ethers listed in the Stockholm Convention (SC) as persistent organic pollutant (POP-PBDEs) in the most relevant plastic fractions in Nigeria. Considering the prohibition of production and the use of POP-PBDEs and knowing that these pollutants are still contained in electrical and electronic equipment (EEE) and associated wastes (WEEE), it is necessary to determine their flows, especially in developing countries with limited end-of-life management. Following the inventory approach of the SC Guidance and utilizing the existing national e-waste inventory together with monitoring data, a Material/Substance flow analysis was conducted using the STAN tool. Within the period of 2000 to 2010, the total import for EEE/WEEE in Category 3 and 4 was approximately 8 million tonnes (Mt) containing approximately 2.4 Mt of polymers. For the inventory year 2010, it was estimated that from these polymers, about 0.8 Mt was still in stock and 1.6 Mt has reached the end-of-life. It was also estimated that approximately 1.1 Mt has ended in dumpsites, 0.3 Mt was burned in the open, and 0.2 Mt was recycled. In the plastic fractions, 1,270 t of POP-PBDEs was contained with about 370 t still in use/stock and approximately 900 t has entered the end-of-life phase. All three major end-of-life treatments result in environmental pollution with associated exposure risk. The implementation of the Stockholm Convention represents an important opportunity to improve this management situation in Nigeria and other developing countries.
