Baggasse preservation: a need for a biotechnological approach

Area of Science:

• Agricultural Science
• Biotechnology
• Materials Science

Background:

• Global paper consumption necessitates alternative fiber sources due to dwindling traditional cellulosic resources.
• Bagasse, a sugarcane industry byproduct, is an abundant, renewable, and cost-effective fiber source for paper manufacturing.
• Effective long-term storage (6-8 months) of bagasse is crucial for consistent supply but faces challenges like microbial degradation and physicochemical properties.

Purpose of the Study:

• To introduce a novel biotechnology-based approach for preserving bagasse for the pulp and paper industry.
• To address the limitations of conventional bagasse storage methods, including cost, energy, and environmental impact.
• To ensure a continuous and sustainable supply of high-quality bagasse fiber throughout the year.

Main Methods:

• Preservation of maximally depithed bagasse in piles using a single application of a preservative mist.
• The preservative formulation includes biodegradable and non-biodegradable chemicals targeting microbial enzyme activity.
• Optimized storage conditions include open, dry, windy, and moderately sunlit sites.

Main Results:

• The biotechnology approach effectively inhibits microbial growth, preserving bagasse quality for extended periods.
• This method is demonstrated to be simple, sustainable, and eco-friendly.
• The new method offers significant advantages over traditional, energy-intensive, and non-eco-friendly storage techniques.

Conclusions:

• Biotechnology provides a viable and superior alternative for bagasse preservation compared to existing methods.
• The proposed method is cost-effective, sustainable, and environmentally sound.
• There is potential for further optimization, automation, and economization of this biotechnological approach for industrial application.
