Abstract

This paper aims to explore whether seaweeds from the Bay of Bengal are available for commercial biofuel production. Seaweeds provide various ecosystem services from marine ecosystems that can be utilized as food, cosmetics, fertilizers, industrial chemical, or biofuel. Other than diversified usefulness, seaweeds could be used in a running vehicle. It can be used as an alternative source of non-renewable energy along with a high potential to produce environment-friendly fuel for the next generations. Developed countries are utilizing seaweeds as essential resources of biofuel with advanced technology, machinery, and skilled manpower. From the physiography of the ocean of Bangladesh, it can be found that seaweeds have a high potential to produce biofuel from the coast and offshore areas. Among different types of seaweeds, biofuel can be produced from lipid & fatty acid, carbohydrate, or protein in them. Therefore, a sustainable SWOT analysis has been conducted to explore the availability and potential of seaweeds for biofuel production. To produce biofuel in Bangladesh due to the lack of investment, advanced technology, well-equipped machinery, and skilled manpower are still in shade. However, if investment and technical equipment are embraced for producing raw material (such as specific species of seaweeds) for the biofuel production those could be exported to the nearest market.

Highlights

  • Seaweeds are the kind of macroalgae or microalgae, which grow in every ocean

  • Eight available seaweeds are found in Bangladesh, which can be used to produce Biodiesel, Bioethanol, Biomethane and Biohydrogen

  • India and Australia are contributing for the preservation of environment by producing biofuel through the low carbon development movement since 2016

Summary

Introduction

Seaweeds are the kind of macroalgae or microalgae, which grow in every ocean. Being located in the tropical area in Indian Ocean, where more than 732 verities of seaweed species are found (Ganesan et al, 2019). Bangladesh is surrounded by the Bay of Bengal in the south, which is a part of the Indian Ocean, has a coastline of 710 km along his southern portion. It is rich in various forms of seaweeds (around 200 variety of species) having huge nutriatious elements (i.e., lipid, protein and carbohydrate) (Ahmed, 2019; Sarkar et al, 2016; Nehal, 2014). Productions of bio-energy from seaweeds are becoming popular day by day in the Asian countries. Seaweeds of this region can be used as a new and alternative source of energy that can enhance solar energy conservation and environment friendly fuel production for various vehicles in near future (Hamouda, 2015)
