The modern manufacturing industry is facing a great number of challenges to establish green sustainability to lessen the threats formed by decadent civilization gradually for years, is the issue itself to solve with proposed solutions from all over the world can invite further unrec-ognized problems which may leave the situation unbearable. Jute is one of the bast fibers which has been proposed widely to accept and marketed as eco-friendly raw material for finished goods production, especially textiles.

In this study, the sequestration and storage capacity of carbon were quantified in canopy trees of Sundarbans - Sundari, Gewa, Baen, Keora, Golpata and Tiger fern- represent the largest part of the whole forest. Different parts of the trees such as branch, leaf, skin and wood were collected to measure carbon in the study area. They have also been selected according to their DBH≥ 10cm. The capacity of sequestration of C fluctuates in different components of a single species. C capture in Gewa, branches having diameter less than 5 cm, was 41.48% and for Sundari it was 41.3 %.

As a developing country, Bangladesh is undergoing a huge expansion in industrial and commercial infrastructures which is resulting in the acceleration of energy demand exponentially and it will continue in the same trend in the coming future. These growing demands have necessitated the approaches to generate energy from the sustainable resources, not only to meet the energy requirements but also to reduce GWP (Global Warming Potential), decrease CO2 emissions, and ensure cost effectiveness in the long run.

In tannery, fleshing is the unavoidable solid waste which has negative effect on the environment. Fleshing contains fat, and protein.In this work, fat extracted fleshing was used for composite fabrication. After collecting limed fleshing, fat was extracted in water bath.The fat extracted fleshing was dried, ground,passes through 80-mesh and homogenized.For proper adhesion and bonding with fleshing powder, epoxy resin and hardener were mixed at various ratios and poured onto an aluminum sheetfor 24 h curing. The mechanical properties of the composite were investigated by tensile strength, elongation at break, and Young’s modulus. The composite was characterized by Fourier Transform Infrared (FTIR) Spectroscopy and Scanning Electron Microscope (SEM) for related functional groups and surface analysis. The investigation provided satisfactory information on the proper bonding of the fleshing powder and resin/hardener. The approach explores the valorization of he waste for managing solid waste in the tannery. Bangladesh J. Sci. Ind. Res.56(3), 215-222, 2021
