From Nature,
With Precision

Suzhou Everwell Biotechnology Co., Ltd. supplies premium-grade compound amino acid powders to B2B fertilizer formulators, importers, and distributors worldwide — 4,000 tons of monthly capacity from a 20,000 m² facility.

A Renewable Source,
Engineered for Consistency

Our powders are produced from high-quality duck feathers through controlled hydrolysis, purification, concentration, and spray drying — delivering consistent quality across 35%, 45%, and 80% amino acid grades plus Protein Powder for foliar fertilizers, fertigation systems, water-soluble blends, and biostimulant formulations.

Every batch begins as natural keratin protein — an abundant, renewable raw material. Through our four-stage process it becomes a fully water-soluble powder that feeds crops, restores soil, and supports sustainable agriculture in more than 20 countries.

Each shipment is verified against agreed specifications and supplied with batch-specific COA documentation. We support OEM and private-label packaging, offering flexibility to meet your brand and market requirements.

Precision at Every Stage

From raw feather protein to premium-grade amino acid powder — a four-stage process engineered for consistency and purity.

Hydrolysis processing facility — controlled temperature tanks
01

Controlled Hydrolysis

High-quality duck feathers undergo precisely controlled hydrolysis to break down protein into individual amino acid chains.

Purification line — filtration and impurity removal
02

Purification

Advanced purification technology removes impurities, ensuring bioavailability and consistent amino acid profiles.

Concentration stage — evaporation and density control
03

Concentration

The purified solution is concentrated to the target amino acid density for each product grade specification.

Final amino acid powder — white, free-flowing
04

Spray Drying

Instant spray drying technology preserves nutritional components, producing a free-flowing, fully water-soluble powder.

Independently Verified
by Eurofins

Every production lot is tested by Eurofins, a CNAS-accredited laboratory, using national standard GB/T 18246-2019 amino acid analysis. Reports issued April 2026.
