Durvela is designed for people who value performance, durability, reliability, and control and being part of an amazing natural process. Combining stainless steel construction, insulation, aeration, mechanical mixing, and sensor ports, Durvela helps transform composting from trial and error into a measurable and predictable process. Customers typically include homeowners, gardeners, food-focused households, vineyards, acreages, orchards, hobby farms, eco-resorts, retreat centres wineries, restaurants, schools, community gardens, landscape companies, and other small organizations and businesses that want a durable, high-performance composting system. See this composter benefit calculator to see how your composter benefits you and the world around you-->

The Durvela 120 is ideal for condos, patios and small households. The Durvela 300 is designed to handle a family's daily food waste. The Durvela 1000 is designed for large gardens, hobby farms, vineyards and cafe's. The Durvela 2000 is designed for restaurants, small breweries, farms, schools and businesses. Unlike many composters, Durvela systems are designed to be a long-term investment. Choosing a slightly larger model often provides the best experience by giving compost more room to aerate, mix, and process efficiently. What size of Durvela composter should I choose ->

Yes. You do not need prior composting experience to use a Durvela system. Durvela was developed to make composting more predictable by combining mixing, aeration, insulation, and monitoring into a structured system. The result is a cleaner, more controlled process that helps both beginners and experienced composters achieve consistent results. Our How Composting Works page provides an easy to understand overview of the composting process, and our Compost Mix Calculator tells you what to add.

If it was once living, there's a good chance it can be composted.

Durvela systems can process most common household and garden organic materials, including fruit and vegetable scraps, coffee grounds, eggshells, garden trimmings, dry leaves, shredded cardboard, sawdust, and suitable wood pellets. With the right balance of materials (carbon, nitrogen, water and oxygen), even more challenging inputs such as meat and dairy can be composted successfully.

The key isn't just what you compost—it's creating the right conditions. That's why Durvela combines insulation, aeration, and mechanical mixing to help support a healthy composting environment. Use our Compost Mix Calculator to create the perfect compost feedstock-->

Avoid plastics, glass, metal, treated wood, glossy packaging, chemicals, pet waste, high salt or very high fat foods or oily products and any materials that may introduce toxins or contaminants.

All Durvela composters come pre-assembled and ready to install on a flat and level surface that won't sink and can support the mass of the composter. For Durvela 300 and larger systems, a solid foundation such as concrete pad or paving stones are recommended. The composter can be secured to the ground with anchor bolts so the base won't move. And for the Durvela 300 and larger systems, but particularly for the Durvela 1000 and Durvela 2000 it is high recommended to have the unloading end oriented towards the sun (e.g. south in the northern hemisphere). The vents on the composter are sized to accommodate a solar powered fan to increase aeration so orienting the solar panel to most sunshine will ensure maximum air flow and sufficient oxygen for efficient composting. Why oxygen is important for composting -->

Yes, composting can save money, although the amount varies depending on your situation. By composting food scraps and yard waste, you can reduce the amount of waste sent to landfill, lower disposal costs where waste collection is volume-based, and produce a valuable soil amendment for gardens, landscaping, and growing food. Finished compost can help reduce purchases of bagged compost, soil amendments, and some fertilizers.

For many Durvela owners, the biggest benefits are not just financial. Composting can also reduce waste, improve soil health, support healthier plants, and provide the satisfaction of turning organic waste into a useful resource. While savings alone may not justify a composting system for every household, many users find the combination of waste reduction, compost production, convenience, and long-term durability makes composting a worthwhile investment.

Composting Cost Benefit Calculator -->

A common composting target is around 25:1 to 30:1 carbon to nitrogen. This helps microbes break down material efficiently while reducing odor risk. Durvela Compost Mix Calculator-->

Moisture supports microbial activity, but too much water can reduce airflow and cause odors. The compost should feel damp, not saturated. If more water is needed, add it into the composter and turn it several times to mix. If it is too wet, add some dry 'browns'. Wait a few days and check again. The Compost Mix Calculator can calculate if you should be adding water (and how much) along with the waste you are adding to the composter -->

Yes. Oxygen is essential for efficient composting.

The microorganisms responsible for breaking down organic matter require oxygen to thrive. When enough oxygen is available, composting remains 'aerobic' (meaning using air to live), allowing materials to decompose more quickly while producing less odor.

Without adequate airflow, compost can become ''anaerobic' (meaning without air). This slows decomposition, creates unpleasant odors, and can lead to a wet, compacted pile.

Durvela systems are designed to support aerobic composting through engineered aeration and mechanical mixing. By helping oxygen reach more of the compost mass, the system creates conditions that support active microbial activity and more consistent compost production.

Temperature is a useful indicator of microbial activity. Warmer compost generally means the process is active and materials are breaking down efficiently. If it is cooler, it is ok, decomposition will still occur, just at a slower rate. Learn more about hot composting-->

Temperatures vary depending on batch size, feedstock mix, moisture, airflow, and outdoor conditions. Larger, well-balanced batches are more likely to heat up. An ideal temperature for microbial decomposition is 55-65C (130-150F). If it is hotter, a Durvela solar fan can be added to push air through the composter and a bit of water can be added to cool it down (add dry 'browns' as well if it is getting too wet).

Composting time depends on input materials, particle size, moisture, temperature, and how often the drum is turned. At higher temperature (55-65C/130-150F) active composting typically takes 1-2 weeks, followed by curing stage of 2-3 weeks. At cooler temperatures it will take a bit longer.

Meat and dairy require careful management because they can increase odor and pest risk as they are higher in nitrogen. If added with appropriate amounts of 'browns' and temperature and moisture are regulated, meat and dairy will be decomposed within the same time period as other kitchen scraps.

If your compost cools down during cold weather, don't worry—this is normal. First, check that the compost has enough moisture and a good balance of nitrogen-rich materials (such as food scraps) and carbon-rich browns (such as sawdust or shredded cardboard). Mixing the contents can help redistribute moisture, oxygen, and active composting organisms throughout the pile.

Adding a larger batch of fresh material can also help generate more biological activity and heat. In very cold conditions, composting may slow temporarily, but Durvela's insulated drum, aeration system, and rotating design help create a more favorable environment for composting than ordinary bins, allowing the process to resume more quickly when conditions improve.

Yes. Insulation helps reduce heat loss, which can help the composting mass remain more biologically active in cool conditions. Durvela composters have 75mm/3" of insulation surrounding the compost. Learn more about cold weather composting-->

Yes. Composting can still occur in cold weather and climates, although decomposition naturally slows as temperatures drop. The key to maintaining activity is retaining heat while providing adequate aeration, moisture, volume, and mixing. Durvela is specifically designed to help manage these conditions, making it a more effective and reliable option for cold-weather composting than conventional bins and tumblers. Learn more about cold weather composting-->

Turning regularly helps mix materials and restore free air space (FAS) which enables aerobic decomposition. Turning once every 1-3 days is a practical starting point, but frequency can be adjusted based on the batch (if there is no fresh compost being added), season (decomposition is often slower in winter), and amount of feedstock being added (turn more frequently with more feedstock).

The composter should contain enough material to retain heat while still leaving room for tumbling, mixing, and airflow. Avoid overfilling the drum. The composter is ideally kept between 40-70% full.

The amount depends on the nitrogen and moisture content of the food scraps. Dry browns such as wood pellets, sawdust, leaves, or cardboard help balance wet kitchen scraps. See our Compost Mix Calculator-->

Yes. Wood pellets and sawdust can be useful high-carbon materials. They should be clean, untreated, and balanced with nitrogen-rich inputs and adequate moisture.

A good practical target is a damp, wrung-out sponge feel. The compost should hold moisture without dripping or becoming sludgy. Water can be added if compost is too dry, and dry browns can be added if the compost is too wet. Our Compost Moisture Calculator provides a suggestion on whether water should be added with your feedstock-->

Add water only when the mix is too dry. Wet kitchen scraps often provide enough moisture, especially when balanced with absorbent browns. Our Compost Mix Calculator provides a suggestion on how much water to add with your feedstock-->

This is most likely becasue compost has fallen between the door and the composter. Clean out any compost that is stuck there with a small brush.

This is because compost has not yet settled inside the composter. Turn the composter a little past where you want it to stop, then when you release the turn handle, it will settle back where you want it.

Yes. Untreated wood pellets can be a clean, consistent brown material providing a source of carbon. They absorb moisture and help balance wet food scraps. As noted in our Compost Mix Calculator, wood products contain large amounts of lignin and crystalline cellulose. Much of this carbon is structurally protected and does not become rapidly available to compost microbes.

For this reason, Durvela treats woody materials as slow-release carbon sources rather than instantly available microbial fuel.

In the calculator, wood pellets are modeled at approximately 30% first-week carbon availability during active hot composting.

Use clean, untreated sawdust. Avoid painted, stained, glued, pressure-treated, or chemically treated wood products.

Yes. Plain, uncoated cardboard can be shredded (large pieces will take longer to compost) and used as a carbon-rich brown material. Avoid glossy, waxed, or heavily printed packaging.

Cedar can be used but is more resistant to breakdown than some other wood materials. Use clean cedar in moderation and balance it with active, nitrogen-rich materials.

Only add compostable packaging if it is suitable for home composting (and break it into smaller pieces first). Many compostable products require industrial composting conditions (shredding and long periods of time). If uncertain, try adding a small amount of it and if breaks down, you know for the future.

Fruit and vegetable scraps, coffee grounds, tea leaves, grains, and plant-based leftovers are generally easier to manage than oily, salty, meat-heavy, or dairy-heavy scraps. See 'What can I compost?' for more-->

Odor usually means the mix is too wet, too nitrogen-rich, compacted, or lacking airflow. Add dry browns and turn the drum to rebalance the batch.

Wet compost often comes from too many food scraps and not enough absorbent browns. Add wood pellets, sawdust, shredded cardboard, or dry leaves.

The batch may be too dry, too cold, too carbon-heavy, or made of pieces that are too large. Add moisture if needed, include more nitrogen-rich material, and turn regularly.

Flies are often attracted to exposed food scraps. Bury fresh scraps under browns, keep the mix balanced, and avoid leaving wet food exposed.

Dry compost may contain too many browns or not enough fresh material. Add water gradually or include wetter nitrogen-rich inputs.

Cold compost may be too small, too dry, too carbon-heavy, or exposed to cool outdoor conditions. Larger, balanced batches are more likely to heat up.

A well-managed aerobic composting system should have minimal odor. Strong smells usually indicate excess moisture, insufficient browns, or poor airflow.

Durvela’s enclosed design eliminates access, but good composting habits still matter. Avoid exposed food scraps and manage high-risk materials carefully.

Cover fresh scraps with browns, avoid overly wet conditions, and keep the system clean around loading areas.

When properly managed, the system can be kept near the home or garden area. Choose a stable, accessible location with suitable drainage and ventilation.

The enclosed drum and controlled loading process are intended to make composting cleaner and more contained than open piles or basic bins.

Stainless steel provides strength, durability, cleanability, and long-term resistance to weather and corrosion. Learn more about the benefits of stainless steel-->

Confirm the exact stainless steel grade in the product specifications. This answer can be edited to match the final production model.

Durvela composters are constructed from high-quality stainless steel, which is specifically chosen for its excellent resistance to corrosion, moisture, and outdoor exposure. Under normal conditions, stainless steel will not rust like ordinary carbon steel.

However, stainless steel is not completely immune to surface staining. In certain environments—particularly coastal areas with salt spray, regions where road salt is used, or where iron particles from tools or grinding operations contact the surface—small spots of surface rust or discoloration can occasionally appear.

These spots are usually caused by contamination on the surface rather than corrosion of the stainless steel itself and are typically easy to remove.

If a rust spot appears:

1. Clean the area with warm water and mild soap.
2. Apply a stainless steel cleaner or a product such as Bar Keepers Friend®.
3. Gently rub with a soft cloth or non-abrasive pad, following the grain of the metal.
4. Rinse thoroughly and dry the surface.

Cleaning with products such as Bar Keepers Friend® helps remove contamination and restore the chromium-rich passive layer that protects stainless steel from corrosion.

Avoid using carbon-steel brushes, steel wool, or ordinary steel tools on stainless steel surfaces, as they can leave behind tiny iron particles that may later rust and create surface staining.

This is one reason Durvela offers a stainless steel compost rake. When unloading compost, a stainless steel tool helps avoid introducing carbon-steel contamination into the drum, reducing the likelihood of surface rust spots while also providing excellent durability in the composting environment.

With occasional cleaning and normal care, the stainless steel used in Durvela composters can provide decades of reliable service in outdoor environments.

Tip: If you live near the ocean, occasionally rinsing the exterior with fresh water can help remove salt deposits and keep the stainless steel looking its best. Minor surface discoloration or isolated rust spots are typically cosmetic only and do not affect the strength, safety, or longevity of the stainless steel.

Durvela composters are built from high-quality stainless steel for long-term durability and minimal maintenance. In most cases, rain and normal outdoor exposure are all the cleaning the exterior requires.

To keep your system looking its best:

• Rinse dirt, dust, or compost residue with water as needed.
• For heavier buildup, wash with mild soap and a soft cloth or sponge.
• Avoid steel wool, abrasive carbon-steel brushes, or harsh chemicals that can scratch the surface or contaminate the stainless steel.
• If you live near the ocean or in areas where road salt is common, occasionally rinse the exterior with fresh water to remove salt deposits.
• Remove any compost residue from door seals and moving components during routine use.

Stainless steel naturally resists corrosion and does not require painting, staining, or protective coatings. With basic care, a Durvela composter can provide decades of reliable service while maintaining its appearance and performance.

What if a rust spot appears?
In most cases, small rust spots on stainless steel are not caused by the stainless steel itself, but by tiny particles of carbon steel that have become embedded on the surface during manufacturing, installation, or contact with metal tools. These spots are usually easy to remove:

1. Clean the area with warm water and mild soap.
2. Apply a stainless-steel cleaner or a product such as Bar Keepers Friend®.
3. Gently rub with a soft cloth or a non-abrasive pad, following the grain of the metal.
4. Rinse thoroughly with clean water and dry the surface.

Products such as Bar Keepers Friend® contain mild acids that help remove contamination from the surface and restore the chromium-rich passive layer that gives stainless steel its corrosion resistance. This process, often called re-passivation, can help return the surface to its original appearance and protective condition.

Avoid using ordinary steel brushes or steel wool, as they can leave behind particles that may cause additional surface rust. If a stain does not come off with normal cleaning, contact Durvela for guidance.

Tip: Minor surface discoloration, tea staining, or isolated rust spots are typically cosmetic and do not affect the strength, safety, or longevity of the stainless steel. Regular cleaning is usually all that is required to keep the surface looking its best.

Durvela is designed as a long-term composting system with robust materials and serviceable components. With proper care and maintenance, your composter should last a lifetime. Learn more about the benefits of stainless steel-->

The system is designed for outdoor use, but placement, maintenance, and local climate conditions can affect long-term performance.

The lifespan depends on materials, use, care, and environment. Stainless steel construction is intended to support long service life.

Wheel-supported rotation helps the drum turn smoothly, making it easier to mix compost and maintain airflow.

Depending on the model, sensor ports may allow temperature probes to be inserted for monitoring compost activity.

Sanitary ferrules provide clean, durable access points for probes or monitoring equipment.

Moisture can be monitored manually or with suitable sensors if the system is configured for probe access.

Advanced monitoring and automation may be possible depending on the final configuration and accessories.

Data logging support depends on the monitoring equipment used. This answer can be updated once compatible accessories are finalized.

Finished compost is dark, crumbly, earthy-smelling, and no longer resembles the original food scraps. It may need curing before garden use.

Use finished compost as a soil amendment, mulch ingredient, or garden top dressing once it is mature and stable.

Yes, mature compost can be used in vegetable gardens. Make sure the compost is fully finished and properly cured before applying around edible crops.

Store finished compost in a breathable container or covered pile where it stays slightly moist but not saturated.

Output volume depends on the amount and type of material added. Composting reduces volume significantly as materials break down.
