Supply chain we control
Who we are now
A quality-led manufacturer, not a commodity supplier.
Biostock is a Mississippi manufacturer of natural bedding and wood pellets. We sit next to our fiber supply, mill it under one roof, and hold a single standard: clean, consistent, low-dust pine that's safe for the animals that live on it.
Most of our category competes on price alone — generic bags, no story, no accountability. We're built the other way: transparent process, controlled inputs, and a real place behind the product. Today that product reaches buyers from national farm-and-ranch retail to premier equestrian venues, and it's the foundation for where we're headed next in bedding, fuel pellets, and sustainable carbon.

Why bedding matters
Bedding is a health decision before it's a purchase.
Every bag we make leads with the outcome in the stall. Here's what clean, consistent, low-dust pine does for the animals that live on it.
Respiratory health
Dust extraction removes the fine particulate that irritates equine airways — the single biggest bedding-related health complaint.
Ammonia control
High-absorbency pine locks away moisture and urine, holding down the ammonia that damages lungs and hooves.
Moisture management
Kiln drying to a controlled moisture point means each bag wicks and dries predictably — a cleaner, drier bed for longer.
Hoof health
A dry, low-ammonia bed protects the hoof capsule and white line — the difference a good bedding makes over a season.
Joint & rest support
Consistent flake depth gives horses a cushioned, inviting surface — better lying time, better recovery.
Consistent quality
One species, one process, one standard. What you open this week is what you open next month — no surprises in the bag.
The Simplicity line
Three products. One clean-pine standard.
Kiln-dried and dust-extracted, securely wrapped and capped, weather-resistant for outdoor storage. Sized for the stall and palletized for the dealer.

Log to bag
Five steps we control, start to finish.
Because we sit next to our fiber and run every stage under one roof, quality isn't a promise we outsource — it's a process we own.
01
Premium pine sourcing
Local southern-yellow-pine residuals — one clean species, never hardwood.
02
Precision shaving
Milled to a consistent flake profile for absorbency and comfort.
03
Kiln drying
Dried to a controlled moisture point for predictable performance.
04
Multi-stage screening
Graded across multiple screens so each SKU is true to spec.
05
Dust extraction
Fines pulled out before bagging — cleaner air in every stall.
Where we're going
From clean bedding to clean energy and carbon.
The same fiber, the same discipline, a bigger mission. Biostock is scaling from premium bedding into fuel pellets and sustainable carbon — keeping the value in the Mississippi community that makes it.
Growth line
Fuel & specialty pellets
Bulk heating pellets and premium hardwood BBQ pellets, built on the same milling backbone — a higher-value home for every ton of fiber.
Sustainability
Residuals, not waste
We start from timber residuals and design out waste — recovering fines into product and keeping clean fiber in a circular, local loop.
The bigger vision
Sustainable carbon
With our partners across the CarbonScale network, we're developing low-carbon and biocarbon pathways that turn Mississippi fiber into durable climate value.
