Surplus Bagasse: From Sugar Mill Boiler By-Product to Global Biomass, Paper, and Substrate Markets<\/p>\n

How mills in Brazil, India, Thailand, and Guangxi are finding commercial buyers for surplus bagasse \u2014 drying logistics, bale moisture specs, and the three industries competing for the same material.<\/p>\n<\/div>\n<\/div>\n

Bagasse: The By-Product That Powers Sugar Mills \u2014 and Increasingly, Much Else<\/h2>\n

Sugarcane bagasse is the fibrous residue remaining after the cane stalk has been crushed to extract juice for sugar or ethanol production. At 48 to 52% moisture immediately after extraction, fresh bagasse retains approximately 50% of the original stalk’s calorific energy \u2014 energy that sugar mills have captured for their own process power since the earliest days of industrial sugar manufacturing. A modern mill burning its own bagasse in high-pressure steam boilers can generate 250 to 280 kWh of electricity per tonne of cane processed \u2014 sufficient to power the mill and export 80 to 150 kWh to the national grid per tonne.<\/p>\n

The introduction of high-efficiency 90-bar boilers at modern Brazilian, Indian, and Thai mills has created surplus bagasse at some operations \u2014 10 to 20% of production without an on-site combustion outlet. This surplus must either be stored for the inter-harvest period or sold to external buyers. External demand has grown significantly since 2015 across three industries: biomass power, paper and fibre board manufacturing, and mushroom cultivation substrate. Baling converts a bulky, wet, loose material into a transportable, storable product with consistent density and format that makes external sale logistically viable. Our guide on how to prevent silage bale spoilage<\/a> covers the storage management principles applicable to bagasse bales during the drying and staging phase.<\/p>\n<\/div>\n

The Drying Challenge: 50% Mill-Exit to Bale-Ready<\/h2>\n

Why Fresh Bagasse Cannot Be Directly Baled for Commercial Delivery<\/h3>\n

Bagasse at 48 to 52% moisture is too wet for any of its three external markets. Biomass combustion buyers specify maximum 20 to 25%; paper mills specify 15 to 20%; mushroom substrate buyers specify 12 to 16%. The most cost-effective drying method at mill scale is spreading bagasse on concrete or compacted earth drying pads in layers 20 to 30 cm deep and turning once or twice daily with a front loader. In Brazil’s S\u00e3o Paulo state dry season (April to September), bagasse reaches 18 to 22% moisture within 3 to 5 days. In India’s monsoon season, pad drying to below 20% may take 7 to 14 days or require active drying tunnels.<\/p>\n

\n
\u274c Deep Piles Without Turning \u2014 Spontaneous Combustion Risk<\/div>\n

Bagasse piles above 40% moisture generate heat through microbial and chemical oxidation at a rate that can raise internal temperatures to 55 to 70\u00b0C within 3 to 5 days. Above 65\u00b0C, slow smouldering combustion begins in the anaerobic pile interior \u2014 a documented fire hazard at sugar mills across Brazil, India, and the Philippines. Limit pad pile depth to 30 to 40 cm and turn every 24 to 48 hours without exception.<\/p>\n<\/div>\n

Three Market Channels and Bale Specifications<\/h2>\n

Channel 1: Biomass Combustion<\/h3>\n

Industrial biomass users \u2014 district heating plants, food processing operations with biomass boilers, co-generation facilities \u2014 are the most accessible external bagasse market. At current Brazilian and Thai prices (USD 18 to 35 per tonne DM), bagasse competes primarily on cost and proximity. Its advantage is volume and logistics simplicity near sugar mills; its disadvantage is moderate ash content (5 to 9% DM) that limits acceptance in low-ash-tolerance combustion systems.<\/p>\n

Channel 2: Paper and Pulp Manufacturing<\/h3>\n

Bagasse pulp is used in paper manufacturing as a non-wood fibre source, producing newsprint, tissue, and packaging paper. Paper mills in China, India, and Thailand specify baled bagasse at 15 to 20% moisture with pith content below 25% (pith produces short, weak paper fibres; the fibrous rind fraction is preferred) and consistent bale weight for automated handling.<\/p>\n

Channel 3: Mushroom Cultivation Substrate<\/h3>\n

Bagasse at 12 to 16% moisture in round bales is used for oyster mushroom cultivation across Southeast Asia and China’s Guangxi and Guangdong provinces. Substrate buyers specify zero visible mould, consistent weight, soil-free pickup protocol, and delivery within 30 days of baling \u2014 the same specification as rice and wheat straw substrate bales. The price premium over biomass (substrate at \u00a5150 to \u00a5220 per bale versus \u00a560 to \u00a5100 for biomass) makes substrate the priority channel. The 9YG-1.0 round baler<\/a> is standard for substrate-spec bagasse bales in Guangxi; the 9YG-1.25A variable-chamber round baler<\/a> serves larger-volume biomass and paper mill supply.<\/p>\n<\/div>\n

\n
\u274c Baling Above 25% Moisture for External Delivery<\/div>\n

Bagasse above 25% moisture in sealed round bales continues self-heating through microbial respiration. Core temperatures above 55\u00b0C within 72 hours are common. Resulting degraded material has lower calorific value (biomass rejection), altered fibre structure (paper quality concerns), and mould development (substrate rejection). Dry to below 20% before baling for any external delivery.<\/p>\n<\/div>\n

\n
\u26a0 Pith Contamination in Paper Mill Supply<\/div>\n

Paper mills penalise or reject deliveries with high pith content because pith cells produce short, weak fibres that reduce paper quality. Source bagasse from mature cane harvested at peak fibre development, and avoid mixing bagasse from immature or stressed cane that produces higher pith ratios.<\/p>\n<\/div>\n

\nWhat is the calorific value of dried bagasse versus coal?<\/span>+<\/span><\/summary>\n
Dried sugarcane bagasse at 15% moisture has a net calorific value of approximately 15 to 17 MJ\/kg \u2014 about 40 to 50% of thermal coal (28 to 32 MJ\/kg). Sugar mills converting from coal to bagasse combustion typically require 2.5 to 3 kg of dry bagasse to substitute for 1 kg of coal. The environmental advantage \u2014 zero fossil carbon from bagasse combustion \u2014 is significant regardless of the energy density penalty.<\/div>\n<\/details>\n
\nIs there a global market for baled sugarcane bagasse?<\/span>+<\/span><\/summary>\n
Limited international trade exists \u2014 primarily from Thailand and Brazil to Asian paper mills and some European biomass facilities. The trade volume is constrained by shipping economics: at per-tonne values of USD 20 to 50, intercontinental shipping cost (USD 60 to 120 per tonne) frequently exceeds commodity value. Regional trade within 100 to 300 km of production \u2014 the economically viable range \u2014 is significantly more active.<\/div>\n<\/details>\n
\nCan bagasse be ensiled for cattle feed?<\/span>+<\/span><\/summary>\n
Bagasse at 48 to 52% mill-exit moisture can be baled and film-wrapped for fermented preservation. The resulting silage has crude protein of 1 to 2% DM and NDF of 60 to 70% \u2014 very low nutritional quality. With supplemental urea treatment and LAB inoculant, the feeding value improves modestly. This is practised at some Brazilian and Indian feedlot operations as a cost-minimisation strategy during periods of expensive purchased roughage but is not the primary application.<\/div>\n<\/details>\n
\nWhat is the price for mushroom substrate bagasse in Guangxi?<\/span>+<\/span><\/summary>\n
In Guangxi’s Nanning and Guigang regions at 2024\/2025 prices, substrate-grade bagasse bales (1.0 m diameter, 12 to 15% moisture, zero mould, 150 to 200 kg) sell for \u00a5100 to \u00a5160 per bale \u2014 approximately \u00a5500 to \u00a5900 per tonne DM. Biomass-grade bagasse at equivalent weight sells for \u00a560 to \u00a5100 per bale. The substrate premium covers the additional drying management and quality confirmation discipline.<\/div>\n<\/details>\n
\nHow does Guangxi’s anti-burning regulation affect bagasse management?<\/span>+<\/span><\/summary>\n
Guangxi’s provincial regulations, aligned with the national 2014 framework, prohibit open burning of sugarcane field trash and bagasse. Enforcement has increased since 2018 with satellite monitoring of burning incidents. The anti-burning regulation has been the primary driver of commercial bagasse baling infrastructure development in Guangxi over the past 5 years \u2014 mills and cane farmers who previously burned field trash now have both regulatory incentive and commercial opportunity to bale and sell.<\/div>\n<\/details>\n<\/div>\n
