Sonali bag
- Plastic-like Jute material developed in Bangladesh
- The Sonali Bag or Golden Bag is a cellulose-based biodegradable bioplastic alternative to plastic bags, particularly polythene bags, developed in Bangladesh by Mubarak Ahmad Khan
- Mubarak Ahmad Khan invented the bag from jute in 2017
- The cellulose used in Sonali Bags is extracted from jute, a major fiber crop grown across the globe.
- Scientists in Bangladesh have developed a method to convert Jute fibre into low cost bio-degradable cellulose sheets named Sonali which can be used as wrapping material and carrying bags.
- Mubarak Ahmad Khan, scientific adviser to the state-run Bangladesh Jute Mills Corporation (BJMC) and leader of the team that developed the new ‘sonali’ says that the physical qualities of the invented jute fibre and plastic are quite similar.
- The bag not only looks and feels like plastic but is also compostable and completely biodegradable.
- The Eco-friendly jute poly bags made up of Sonali can be used in garments and food packaging work and they are not harmful to human health.
- Polythene bags were banned in Bangladesh in 2002 because of environmental concerns.
- Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass.
- Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all three
