Green Elephant

We’re going to take a look at Green Elephant Biotech’s 96-well PLA microplates made from plant-based polylactic acid (PLA), produced by fermenting corn or sugar cane. Green Elephant Biotech claims to deliver a like-for-like 96-well plate with around 50% less embedded carbon than the virgin polystyrene plates most labs use today.

The products featured in this review were provided by Green Elephant Biotech for evaluation at no cost. No payment or other compensation was received. This is an independent review; Green Elephant Biotech had no editorial control over the content, and both strengths and limitations are discussed.

We have also recorded a full video review of this product, where we walk through what the product is, how it performs, and evaluate the sustainability claims in detail.

What do Green Elephant Biotech offer?

Green Elephant Biotech offers 96-well microplates made from polylactic acid (PLA), a plant-based, biodegradable polymer derived from the fermentation of corn or sugar cane. PLA has comparable mechanical properties to traditional polystyrene, but with reduced embedded carbon. The plates come in three optical formats, designed to match the assays you’d run on premium polystyrene plates today.

The three optical formats available are:

Clear — Optical tests and microscopy applications

Black — Fluorescence-based assays

White — Luminescence assays

The plates meet ANSI/SLAS 1-2004 through 4-2004 standards, so they share the standard 96-well footprint and work with the plate readers, liquid handlers and automation systems most labs already have. Green Elephant Biotech maintains a published list of compatible devices on their website, covering microplate readers, pipetting systems, robots, SPR systems and flow cytometers. If your instrument isn’t listed, you can request a free 3-pack trial and test it in your own lab.

Reasons to be impressed with Green Elephant Biotech

• The plates perform like a standard 96-well plate
  Theoretical volume of 372 μL/well with a working volume of 50–200 μL/well are well within the norms for any 96-well workflow. The plates stack cleanly, are clearly numbered and labelled, and from first impressions feel exactly like the plates you’d reach for today.

• The plates have ~50% lower embodied carbon
  The published LCA reports approximately 50% lower CO₂ per plate compared with virgin polystyrene equivalents. Even using the more conservative figure that doesn’t credit biogenic CO₂ uptake during corn growth, the reduction is still around 30%. The savings come from the raw material (plant-based PLA) and the disposal step (lower-carbon incineration of plant-based vs petroleum-based plastic).

• The plates are price-matched to premium polystyrene plates
  Green Elephant Biotech intentionally positions their plates at the premium end of the market but at the same price point as the established premium plate brands, so there is no “green premium” at procurement.

• The plates are a drop-in swap
  ANSI/SLAS compliance plus a published compatible-device list mean switching is a like-for-like swap on workflow rather than a process redesign.

Limitations and Trade-Offs

• Not autoclavable
  Autoclaving is not supported. If autoclaving is part of your standard workflow, the plates won’t be a drop-in fit without adjusting your process upstream.

• Upper temperature limit of 40°C
  The stated operating range is −80°C to +40°C. Heat-sealing has been validated separately at 160°C with 14-day storage performance, but anything above 40°C is outside spec for the plate itself.

• LCA is not third-party verified
  The Life Cycle Assessment is supplier-authored. The sources (EcoInvent, GEMIS) and methodology look as you’d expect, and the underlying data is available for inspection. But procurement teams that need verified Scope 3 data should treat the figures as supplier-reported for now.

• Freight and waste emissions excluded from the Net Zero plan
  Green Elephant Biotech’s current Net Zero plan excludes upstream and downstream freight as well as waste-related emissions due to data availability. They have confirmed this data is now being tracked through other certifications, and we hope to see it included in future Net Zero plan updates.

I also received feedback from someone I know in a lab who had tested an earlier generation of these plates against a premium polystyrene reference, and they noted a slight difference in background absorbance. The plates have evolved since that earlier batch, and the cleanest way to know how the current generation performs in your hands is to test them on your own assay, which is what the 3-pack trial is for.

Price

Prices below are taken directly from the Green Elephant Biotech website at the time of review.* The plates are sold in 25- or 100-plate packs.

White & Black: €173 (25 plates) – €478 (100 plates)

Clear: €87 (25 plates) – €282 (100 plates)

*Prices correct at the time of review

The plates are positioned at the premium end of the 96-well plate market, but matched on unit price with the established premium brands, so the carbon saving doesn’t come with a procurement cost.

Why this matters

96-well microplates are one of the highest-volume consumables in any lab, and almost all of them are virgin polystyrene derived from fossil fuels. That adds a quiet but meaningful contribution to a lab’s Scope 3 footprint, year after year, that most procurement reviews never look at.

Green Elephant Biotech addresses this directly with a plate that should perform like the polystyrene equivalent you use today. Same footprint, same automation compatibility, same volume specs, but with roughly 50% less embodied carbon. It’s a like-for-like swap that doesn’t require a change in workflow or budget.

For labs considering this product, I’d recommend watching the full video review and requesting the 3-pack trial from the Green Elephant Biotech website. Please mention you heard of Green Elephant Biotech through the Sustainable Steps review to help us track the impact of these reviews.

Frequently Asked Questions

What is a PLA microplate and how is it different from a polystyrene plate?

PLA microplates are made from polylactic acid. a plant-based, biodegradable polymer fermented from corn or sugar cane, rather than the petroleum-based polystyrene used in most 96-well plates today. PLA delivers comparable mechanical and optical performance for most assay types, but with around 50% less embodied carbon, primarily from the raw material and the disposal phase.

Do Green Elephant Biotech PLA microplates work with my existing plate reader and lab automation?

Yes. The plates meet ANSI/SLAS 1-2004 through 4-2004 standards, which means they share the standard 96-well footprint expected by most plate readers, liquid handlers and automation systems. Green Elephant Biotech maintains a published compatibledevice list on their website. If your specific instrument isn’t listed, the 3-pack trial is the cleanest way to validate compatibility in your own lab.

Can Green Elephant Biotech PLA microplates be autoclaved?

No. PLA microplates are not autoclavable, and the stated upper temperature limit is +40°C. If autoclaving is part of your standard workflow, you’ll need to handle sterilisation upstream of the plate. Heat sealing is supported separately at 160°C with 14-day storage performance.

How much carbon can a lab save by switching to PLA microplates?

The published LCA reports approximately 50% lower CO₂ per plate compared with virgin polystyrene. Using the more conservative figure that doesn’t credit biogenic CO₂ uptake during corn growth, the reduction is still around 30%. Savings come primarily from the raw material and the disposal phase. Packaging, freight and energy emissions are broadly comparable to a polystyrene equivalent.
