The Sugarcane Bagasse Production, Storage, and Characteristics

How Bagasse is Extracted and Refined

Processing sugarcane bagasse into packaging requires several technical steps:

Step

Aspect

Details

Extraction

Raw Material

Sugarcane bagasse, 30–35% of the cane's biomass, is produced after juicing from stalks.

Moisture Content

Drying fresh bagasse before processing is necessary because it contains 40-50% moisture by weight.

Drying

Mechanical Drying

Bagasse is dried to below 10% moisture using rotary or belt dryers. Preventing microbial growth and ensuring storage stability is essential.

Pulping

Mechanical Pulping

Disc refiners or hammer mills separate bagasse fibres.

Chemical Pulping

Processes like soda or kraft can break down lignin and hemicellulose. The average chemical pulping yield is 45-55%.

Refining

Fibre treatment

The pulp is mechanically refined to improve fibre bonding and flexibility, often reaching 300-400 mL CSF.

Additives

Strength and water resistance can be improved with biodegradable binders or coatings.

Moulding and Forming

Process

The pulp is thermoformed at 180-200°C and 2-5 MPa.

Product Specifications

Typical products include plates, trays, and containers with 1-3 mm thickness and 300-500 kg/m³ density.

Maintaining Quality and Usability in Storage

  • Dry storage. Bagasse should be stored in a dry, well-ventilated area to avoid mould and fibre degradation. Keep moisture levels in check.
  • Manage temperature. They stay structurally intact when stored at a stable temperature. Extreme heat can warp or brittle.
  • Eliminating pests. Pest control protects stored bagasse from insects and rodents that could degrade it.
  • Packaging. Packaging finished bagasse products in moisture-resistant material protects them from humidity and physical damage during transport and storage.

Physical and Mechanical Packaging Properties

Sugarcane bagasse has significant physical and mechanical properties for packaging:

  • Durability and Strength. Has 10-20 MPa tensile strengths. Depending on thickness and density, compressive strength is 5-15 MPa.
  • Biodegradability. Industrial composting meets ASTM D6400 and EN 13432 compostability standards in 45-60 days.
  • Thermal Insulation. Have a thermal conductivity of 0.04 to 0.06 W/m·K, which makes them ideal for modulated food packaging insulation.
  • Moisture Resistance. PLA or beeswax coatings can reduce 24-hour water absorption to 10%.
  • Lightweight. Lighter bagasse-based packaging products (300-500 kg/m³) may shipping costs and improve handling efficiency compared to conventional supplies.

Sugarcane Bagasse: Chemical Makeup

Fibrous sugarcane bagasse is made of organic materials, mostly:

  1. Cellulose. 40-50% bagasse weight. This forms long glucose chains and is the main structural component.
  2. Hemicellulose. 20-30% of bagasse. The filler between cellulose fibres is hemicellulose, a complex carbohydrate of sugars.
  3. Lignin. 20-25% of bagasse. Glucose and hemicellulose are bound by lignin, a rigid, complex polymer that resists decomposition.
  4. Other Components. 5-10% proteins, ash, waxes, and extractives.

Effects on Biodegradability and Compostability

Because of its unique chemical composition, bagasse decomposes and returns to nature in different ways:

  • Cellulose. Bacteria and fungi use enzymes to break down cellulose into glucose. High cellulose content speeds composting because microbes can quickly eat it.
  • Hemicellulose. Hemicellulose breaks down more quickly than cellulose due to its flexibility. It accelerates microbial growth, aiding composting.
  • Lignin. Composting lignin is more complex and slower than cellulose and hemicellulose. Lignin bulks compost, improving structure and aeration but slowing composting.

Uses of Sugarcane in Product Packaging

Sugarcane bagasse packaging has various benefits in the retail and food service industries. These containers are entirely biodegradable and compostable, which aligns with environmental objectives.

They are well-built to withstand hot, cold, and oily foods. These packaging are also free from plastic packaging toxins and chemicals and meet the safe standards for food contact.

Sugarcane containers provide natural insulation that keeps food warm. This makes them ideal for hot and cold use. Growing consumer demand for eco-friendly packaging and showcasing environmental responsibility boosts brand image.

Frequently Asked Questions

Does food packaging with sugarcane bagasse have drawbacks? 

High-temperature sensitivity is a minor drawback of sugarcane bagasse packaging. Temperatures above 95 degrees Celsius weaken bagasse products. This limitation can hinder high-heat-resistant applications. 

It may also face issues like:

  • Hot Liquids. Extended exposure to hot liquids can weaken the material, causing leaks or deformations.
  • Grease Resistance. Bagasse has natural water resistance, but it may not work well with greasy or oily foods without coatings.

What are some ways to mitigate the drawbacks of bagasse packaging? 

Food packaging companies offer packaging solutions to mitigate these drawbacks:

  1. Coatings and Additives. Biodegradable coatings improve heat and grease resistance.
  2. Mixing Materials. Combining with other sustainable materials improves its performance, thus expanding its uses.
  3. Targeted Applications. Paying particular attention to uses where resistance to high temperatures is less important, like packaging for cold foods, one-time-use dishes, and medical storage needs.

What makes sugarcane containers different from other types of packaging?

Sugarcane fibre is an excellent alternative to paper, styrofoam, and plastic. Senior scientist Olga Naidenko says styrofoam has well-documented environmental and health risks. It takes 500 years to decompose and uses 30% of landfills. About 20% of all Styrofoam is not disposed of in landfills.

Sugarcane fibre food packaging products are cheaper and comparable in durability. These containers are porous and absorb excess moisture, which makes them breathable and drier for produce.
