Eco-Friendly Soil Remediation: MGDA & GLDA vs EDTA

Soil contamination with heavy metals is no longer just an environmental concern; it’s a global challenge affecting agricultural productivity and human health. While traditional solutions like EDTA have been the industry standard for decades, the shift toward Green Chemistry is non-negotiable in 2026.

At Yuanlian Chemical, we are leading this transition by providing high-performance, biodegradable alternatives: MGDA (Methylglycine diacetic acid) and GLDA (Tetrasodium glutamate diacetate).

The EDTA Dilemma: Why the Industry is Shifting

For years, Ethylenediaminetetraacetic acid (EDTA) was favored for its high removal efficiency. However, its persistence in the environment and poor biodegradability pose significant ecological risks.

The Power Duo: GLDA & MGDA from Yuanlian Chemical

1. MGDA: The High-Efficiency All-Rounder

If your remediation project faces fluctuating soil conditions, MGDA is the superior choice.

• Broadest pH Range: MGDA remains stable and effective across a massive pH spectrum (2 to 13.5), making it ideal for diverse soil types, from acidic industrial sites to alkaline terrains.

• Comparable Performance: Studies show MGDA matches EDTA in heavy metal elimination rates while being significantly more eco-friendly.

2. GLDA: The Eco-Conscious Powerhouse

Derived largely from plant-based materials, GLDA is the go-to for projects prioritizing a low carbon footprint.

• High Solubility: It works exceptionally well in aqueous soil washing processes.

• Safety Profile: It is non-toxic and non-sensitizing, ensuring safety for both the technicians and the local ecosystem.
