Abstract

The life cycle assessment is conducted in order to assess the impact of mangrove woodchip production in Bintuni bay, West Papua Indonesia on the environment. Study includes the analysis of non-renewable energy use (MJ), global warming potential or carbon footprint (kg CO2), acidification potential (kg SO2) and ozone creation potential (kg O3) of mangrove logging, processing and shipment. Mangrove woodchip production consumes 960 MJ of non-renewable energy and gives out 59.59 kg CO2, .383 kg SO2 and 30.39 kg O3, which is the lowest in comparison with other wood products. Mangrove processing incur less fuel because it is delivered in bulk to the processing area via barges in comparison to other wood products The current shipping of mangrove woodchips to customers has the greatest environmental impact because of the use of bunker fuel. The processing of mangrove woodchips used diesel exclusively for fuel in its power sources. Forest residues from logging can be a source of renewable fuel and may also be another source of new products.

Highlights

  • Mangrove forests are among the world’s most productive ecosystem

  • Gasoline contributes to 18% of non-renewable energy (NRE) use which is used exclusively on logging operations.About 49% of the NRE used is from the processing of woodchips while 33% is used on transport.Result shows that49% of the NRE use is forprocessing woodchips, 21% forhauling

  • The use of less NRE on the harvesting and processing may attribute to low fuel consumption. via barges and incur less fuel in comparison to Logs are delivered in bulk to the processing area harvested logs that are delivered by trucks
