1. Rice Hull Wall Cladding and Decking
There are a lot of composite decking and siding options on the market these days, and recycled plastic is usually the dominant ingredient. Reusing plastic is an admirable sustainability mission, but composites have advanced past plastic. A newer composite called Acre by Modern Mill—that’s mostly made from rice hulls—more closely resembles wood in the performance of the material. Unlike mostly plastic composites, Acre dust is similar to wood sawdust, and it doesn’t create adhesive sticky snowflakes with a persistent static charge while being cut on a table saw. The lack of potential for little shocks and the absence of plastic composite dust that can attach to everything in its path combine to make working with Acre easier.
But the best part is that the rice hull composite decking, siding, and millwork takes paint and stain beautifully, maybe even better than standard lumber. Modern Mill says it’s also water-resistant, stain-resistant, pest-resistant, and guaranteed not to rot or crack.

I’ve worked with traditional composite decking before, and the static cling from cutting plastic-based materials can be a real hassle—dust sticking to tools, clothes, and even my dog who wandered too close to the workshop! What I love about rice hull composites like Acre is how they solve this problem. The material behaves more like wood, which makes it a dream for DIYers who want a clean workspace. Plus, rice hulls are a byproduct of rice production, so using them diverts agricultural waste from landfills. According to industry reports, over 100 million tons of rice hulls are produced globally each year, and repurposing even a fraction of that for building materials can significantly reduce environmental impact. If you’re considering this for an outdoor project, keep in mind that proper sealing can enhance its longevity, especially in humid climates. A quick tip: test your stain on a small piece first, as the material’s unique texture might absorb it differently than wood.
2. Bamboo Lumber
Another sustainable wood alternative is bamboo, which has the natural benefits of being insect- and rot-resistant. Plus, it’s a fast-growing and sustainable alternative to wood. Until about 20 years ago, sourcing it required an overseas order, but it was worth the trouble for ease of installation or durability in busy households. These days, Netherlands-based Moso makes bamboo decking, siding, square stock lumber, 2x beams, and tongue-and-groove boards for porch flooring, soffits, and fences. In North America, the products appear under the names Bamboo Outdoor Thermo and Bamboo Outdoor N-Durance. Thermo performs similarly to exotic hardwoods and is Class A fire-rated, and N-Durance is similar to IPE and Cumaru.

Bamboo’s rise in popularity isn’t just hype—it grows up to three feet a day in ideal conditions, making it one of the most renewable building materials out there. I installed bamboo flooring in my home office a few years back, and it’s held up amazingly well against daily wear, even with kids and pets running around. One thing to note: bamboo’s durability depends on proper treatment. For instance, Moso’s Thermo process heats the bamboo to enhance its strength, making it comparable to hardwoods like teak. If you’re eyeing bamboo for outdoor use, check the fire rating for your area’s building codes, as the Class A rating can be a big plus. Cost-wise, bamboo can be pricier than pine but often cheaper than exotic hardwoods—expect to pay around $3 to $7 per square foot for flooring, depending on quality. A pro tip: always acclimate bamboo to your home’s humidity before installation to avoid warping.
3. Paper Wall Studs
Recycled paper might just be a game changer when it comes to building stud walls. The company Wood Tube developed paper studs for use in non-load-bearing walls to reduce the construction industry’s impact on climate. Easy to cut with standard tools like a miter saw, the studs are lightweight and can be installed with standard fasteners to reach up to 13 feet tall. Since it’s made from paper, a Wood Tube stud must never come in contact with water. So, make sure you are ready to accept delivery and have a dry place to store the tubes while waiting to begin installation.

I was skeptical about paper studs at first—paper in construction? Really? But after seeing them in action at a friend’s renovation, I’m impressed by how lightweight yet sturdy they are for non-load-bearing walls. They’re made from tightly compressed recycled paper, which gives them surprising strength, and they’re about 30% lighter than wood studs, making them easier to handle. The catch is moisture—keep them dry at all costs, or they’ll lose integrity fast. For a small interior project, like a partition wall, they’re a budget-friendly option, often costing half as much as traditional lumber studs. If you’re eco-conscious, you’ll appreciate that they’re made from recycled materials, diverting tons of paper waste from landfills annually. My advice: double-check your storage setup and consider a dehumidifier if you’re in a damp climate.
4. Wood Composite Siding and Decking
Wood composites aren’t a new alternative, but they are becoming more advanced. Molded from real oak boards, Millboard actually looks and feels like real wood, so once you’ve found the right tint, you won’t have to repaint the surface. The maker hand-molds it into decking and siding that performs similarly to real wood with the high performance of a hybrid of polyurethane with a polymer resin core that’s reinforced with fiberglass for extra strength and material stability. The top layer is produced using the same pliable material as the soles of shoes, and it resists scratches and stains. Plus, it’s non-porous, rot-resistant, and lighter than wood, too, so it’s worth considering for shower walls, tub surrounds, backsplashes, pool decks, and outdoor furniture. There are a variety of decking and siding options, and the company offers free samples, so you can try the material before committing to a big project.

I’ve seen Millboard used on a neighbor’s pool deck, and it’s uncanny how much it looks like real oak—nobody could tell the difference! The fiberglass reinforcement makes it incredibly durable, and I like that it’s low-maintenance, especially for outdoor areas exposed to weather. Composites like these can last 25-30 years with minimal upkeep, compared to wood decking that might need refinishing every few years. The non-porous surface is a lifesaver for stain-prone areas like kitchens or patios. One thing to consider: while the upfront cost might be higher—around $8 to $12 per square foot—it saves money over time due to its longevity. My tip? Request those free samples to test how the material feels in your space, especially if you’re matching it with existing decor.
5. Hemp Trim, Cabinets, and Flooring
It seems like hemp has been showing up everywhere lately, from home goods to wellness products. Luckily, building products haven’t been overlooked by the hemp innovators. Made from fiber hemp stalks and a soy-based adhesive, HempWood is an engineered non-structural hardwood designed for interior flooring, cabinets, counters, trim, and furniture. Comparable to American white oak, these hemp panels consist of three layers of cross-laminated solid hemp and the flooring is 20 percent harder than hickory. As it’s a USDA-Certified BioBased Product, 1 pound of carbon is stored in every 2 feet of HempWood flooring so it helps reduce the overall environmental impact of a home makeover project.

HempWood’s durability blew me away when I checked out a sample at a local showroom—it’s tough as nails yet has a warm, natural look that rivals traditional hardwoods. The fact that it stores carbon is a big win for eco-minded folks like me; it’s like building sustainability right into your home. Hemp grows in just 120 days, compared to decades for oak, so it’s a no-brainer for reducing deforestation. Installation is straightforward, but I’d recommend using a high-quality underlayment for flooring to boost sound insulation. Cost-wise, expect to pay around $5 to $9 per square foot, which is competitive with mid-range hardwoods. One heads-up: check for VOC emissions in the adhesive to ensure good indoor air quality, especially if you’re sensitive to chemicals.
6. Cork Walls and Floors
Renewable and biodegradable, cork is another sustainable wood substitute that’s being used in homes as flooring, ceilings, and wall cladding. Made from the outer bark of an oak tree, the Thermacork’s cork insulation panels can be used on exteriors and help enhance the insulation value of a wall system with its R-4 per inch rating. For those who love the look of wood flooring and want to max out on sound absorption in a media room or busy open floor plan, the brand Cancork has a variety of wood-grain cork flooring options called iCorkfloor. They digitally print the wood grain on the 3-millimeter-top layer of cork to achieve the look. The brand also makes on-trend acoustic cork wall panels that fit in seamlessly with many modern and transitional interiors.

I put cork flooring in my home theater, and it’s been a game-changer for sound quality—those acoustic properties really shine in a media room. Cork’s natural insulation also keeps spaces cozy, which I noticed during a chilly winter. The R-4 rating means it adds decent thermal resistance, potentially cutting heating costs by 10-15% in well-insulated rooms, based on energy studies. It’s soft underfoot, too, which is great for families with kids. Installation is forgiving, but make sure your subfloor is perfectly level to avoid issues. Cork flooring runs about $4 to $8 per square foot, which is reasonable for its benefits. My advice: go for a sealed finish to protect against spills, especially in high-traffic areas like kitchens.
