Acacia: Tannin for Tanning and Charcoal — A Reforestation with Guaranteed Industrial Market

The black acacia (Acacia mearnsii) is one of the forest species with the highest economic security in Southern Brazil — with a guaranteed market for tannin for tanneries and wood for charcoal. Rio Grande do Sul concentrates more than 200 thousand hectares of acacia and is the world's largest producer of acacia tannin extract, with exports to tanneries in Italy, Germany, and China.

The acacia has a short cycle of 7 to 8 years, grows in low fertility soils, and the rural producer is guaranteed a purchase by Tanac (from the Ledesma group). It is one of the few reforestations with a guaranteed purchase contract before planting — minimal risk for the family producer. When acacia is planted with quality genetic material and integrated into the tannin industrial chain, excellent economic growth can be achieved. This segment can contribute significantly to job and income generation in Brazil.

Join our strategic actions for the implementation of the best solutions in the Brazilian agribusiness sector. Our activities, studies, and advanced research encompass 20 chains and the 255 segments of national agriculture — from the grain chain to sustainable extraction, through horticulture, fruit production, livestock, and much more.

The Innovation for Brazil to Produce More series was developed precisely to identify and implement the best solutions available in Brazil and around the world across the 255 segments of the agribusiness sector — with accessible technical language, updated data, and a focus on practical results for producers, suppliers, governments, and marketers.

1. Opportunities for Small Rural Producers

How to produce quality acacia for the tannin and wood market

Quality acacia for tannin requires bark with a high tannin content — selected genetic material and proper fertilization. The bark represents 20 to 25% of the weight of the trunk and is the most valuable product of acacia.

✔ Selected genetic material from Tanac — clones with high tannin content

✔ Spacing 2×2m to 2×1.5m — high density for greater bark production

✔ Fostering contract with Tanac — seedlings, assistance, and guaranteed purchase

✔ Wood for charcoal: high-value co-product for steelmaking and barbecues

✔ PRONAF Forest and BRDE for acacia from Rio Grande do Sul

The E-Book 01 — Strategic Manual for the Small Rural Producer presents, in detail, the best solutions for this segment and another 254 in Brazilian agribusiness — focusing on method, cost reduction, and progressive growth from Agro 1.0 to Agro 6.0. Access now for BRL 99.00 →

4. Opportunities for Small Agricultural Product Merchants

How acacia generates business for tanneries, carbonizers, and the tannin market

The acacia tannin extract is exported to tanneries in 50 countries — with Tanac being one of the largest tannin companies in the world. The integrated producer has a purchase contract and reference price before planting — security nonexistent in other crops.

The premium acacia charcoal for the artisanal barbecue market reaches R$ 8 to R$ 15/kg in premium packaging, vs. R$ 2 to R$ 3/kg for bulk charcoal. Identified origin and artisanal packaging triple the value.

Products with high commercial potential

The main products derived from this segment for local retail and foodservice:

Tannin extract for tanneries — guaranteed export;

Premium acacia charcoal — artisanal barbecue; high value;

Acacia wood for sawmills — co-product of increasing value;

Acacia biomass — bioenergy;

Forestry fostering with acacia — low-risk income;

Certified acacia charcoal — growing premium market.

Merchant profiles and their specific opportunities

✔ Integrated producers: acacia with Tanac contract

✔ Artisan carbonizers: premium acacia charcoal

✔ Tanneries: tannin extract for bovine leather

✔ Charcoal distributors: premium for barbecue

✔ Sawmills: solid acacia wood

✔ Forestry consultants: management and fostering of acacia

Growth strategies for the local merchant

The acacia producer who carbonizes wood in an artisanal oven and packages with a premium brand transforms charcoal from R$ 2/kg into a product at R$ 12/kg with an investment of R$ 3,000 to R$ 8,000 in oven and packaging.

The PRONAF Forest and BRDE cover plantings. The Pronampe finances carbonizers and distributors.
