Expand Your Composting System Effortlessly

🔁 Perfect for Compost Rotation

Upgrading to a multi-bay setup allows you to manage active waste and maturing compost simultaneously. Leave one side to decompose while filling the next—ensuring a continuous supply of rich organic soil food for your garden.

🧱 Scalable & Built to Grow

Whether you need double the space or an entire commercial-sized system, our modular layout grows with your garden. Simply attach additional 3-sided add-ons to expand into a triple-bay, quadruple-bay, or custom length system.

🧩 3-Side Seamless Attachment

Designed specifically as an extension module, this kit includes 3 side panels and 2 posts. It connects directly onto the existing frame of your original Tekplas bin—no need to buy a second full standalone unit.

♻️ Sustainable Recycled uPVC

Built with environmental responsibility in mind, this expansion unit incorporates recycled uPVC.

• Note: As part of our eco-friendly manufacturing process, minor surface blemishes or subtle color variations may occur naturally in the plastic—a badge of true sustainability!

🌡️ Thermal Insulation for Faster Results

Constructed using hollow uPVC extrusions with internal webbing. This rigid design traps air pockets, acting as an insulator to keep internal heat high for quicker organic breakdown.
