Reencle Electric Composter: 20 Questions Answered Before You Buy

If you're researching the Reencle electric composter, you probably have a list of questions — about smell, noise, what you can put in it, what you get out of it, and whether it's meaningfully different from the other electric composters on the market. This guide answers the 20 questions we hear most often, with straightforward, honest answers backed by how the machine actually works. No marketing language. Just what you need to know before you decide.

Q1. What exactly is Reencle, and how is it different from other electric composters?

Reencle is a countertop electric composter designed for continuous indoor use. It processes household food waste — including meat, fish, dairy, and cooked leftovers — using a resident population of living microorganisms maintained inside the machine.

The key distinction from most other electric composters on the market is the biological mechanism. Most competing devices are primarily dehydrators: they use heat and sometimes grinding to reduce food scraps to a dry, shelf-stable material. That material looks like compost but has not undergone biological decomposition. It is dried and reduced in volume, but it has not been transformed by microorganisms.

Reencle uses actual aerobic biological composting — the same process that happens in an outdoor compost pile, but accelerated by a controlled environment. The microorganisms in the machine consume and metabolize organic matter, breaking it down into stabilized organic compounds. The output is biologically active in a way that dehydrated material is not.

Q2. How does Reencle actually work?

The machine maintains three conditions that keep its resident microbial community active and productive:

Heat. The interior is warmed to approximately 35–45°C (95–113°F) — the optimal temperature range for mesophilic composting microorganisms. This is warm enough to accelerate biological activity significantly above room temperature, but not so hot that it sterilizes the microbial culture.

Aeration. A mixing mechanism turns the contents continuously or at intervals, ensuring oxygen reaches the entire mass. Aerobic decomposition (with oxygen) is faster, more complete, and odor-suppressed compared to anaerobic decomposition (without oxygen).

Moisture regulation. The machine manages moisture passively, maintaining the balance that keeps microorganisms active without creating waterlogged, anaerobic pockets.

You add food scraps throughout the day as you generate them. The microbial community processes the material continuously. Periodically — typically every few weeks to a few months depending on how much you add — you remove a portion of the mature output from the bottom of the machine and the cycle continues without interruption.

Q3. Does it really make compost, or just dried food scraps?

It makes real compost output — but with a distinction worth understanding.

What you remove from the Reencle is technically pre-compost or immature compost. The microorganisms have already done the primary work of breaking down organic matter, but the material benefits from a short additional curing period before being applied to plants.

The difference from dehydrators is significant:

• Dehydrator output is dried food material. The organic compounds are intact; they have not been broken down by microorganisms. Applied directly to soil, it continues to decompose there — drawing nitrogen from the soil in the process, which can temporarily stress plants.
• Reencle output has already been biologically processed. The microbial community has consumed and metabolized the organic material. Applied to soil after a curing period, it adds stable organic matter and beneficial microorganisms rather than competing with plants for soil nitrogen.

Allow the Reencle output to cure in an open container or small pile for 3 weeks or more before applying it to plants. After curing, it is safe to mix directly into potting soil, raised beds, or garden beds.

Q4. How long does it take to process food waste?

Most kitchen food scraps — vegetable peels, fruit scraps, cooked grains, bread, eggs — process within 2 to 24 hours. Denser inputs like meat and fish take longer, typically 24 to 48 hours.

This timeline is for the primary breakdown phase. The material continues to be worked by the microbial community after it has been initially processed, becoming progressively more stable over time. The output you remove from the machine has typically been in the system for days to weeks — which is what makes it more mature than fresh additions.

For practical purposes: add food waste when you generate it, and check the fill level periodically. When the machine is about 80% full, remove a portion of the output from the bottom and set it aside to cure.

Q5. Does Reencle smell?

Under normal operating conditions, no — the Reencle does not produce a noticeable smell.

The aerobic biological process it uses produces carbon dioxide and water vapor, not the hydrogen sulfide and ammonia compounds responsible for the foul odor of rotting food or poorly managed compost. The machine's carbon filter additionally captures any volatiles before they reach the room air.

When you might notice an odor:

• Immediately after adding a large quantity of strong-smelling food (fish, highly fermented items). This dissipates quickly as the material is processed.
• If the filter is overdue for replacement and has lost its absorption capacity.
• If you add too much liquid at once, creating temporary anaerobic conditions. Drain excess liquid from wet foods before adding.
• If the microbial culture is stressed by an unusual input (large amounts of strongly acidic food, for example).

In a well-maintained Reencle with a fresh filter, most users report no detectable odor from across the room.

Q6. How loud is it?

Reencle operates at approximately 35–45 dB during mixing cycles — roughly equivalent to a quiet library or a low-volume conversation. The mixing mechanism runs periodically, not continuously, so the machine is not constantly producing sound.

For comparison: a typical refrigerator operates at 35–45 dB. Most users find the Reencle's operating sound comparable to or quieter than standard kitchen appliances.

The machine is quiet enough to use in a kitchen, pantry, or utility room without being disruptive during normal household activity. It would be noticeable in a very quiet bedroom at night if placed close to a sleeping area.

Q7. How much food waste can it handle per day?

The Reencle is designed for a typical household generating 1–2 kg of food scraps per day (2–4 lbs). This covers the food waste generated by a 2–4 person household.

Processing capacity depends on the balance of what you add. A steady input of varied kitchen scraps — a mix of vegetables, some protein, some grains — processes efficiently. Large single additions of very dense or liquid-heavy food can temporarily slow the system.

Practical guidance:

• Add food scraps throughout the day as you generate them rather than all at once
• Chop or break dense items into smaller pieces to increase surface area and accelerate breakdown
• Drain excess liquid from soups, sauces, or very wet produce before adding

Q8. Can I put meat and fish in it?

Yes. This is one of the meaningful practical advantages of Reencle over outdoor composting and over most competing electric composters.

The microbial culture in Reencle is capable of breaking down animal proteins effectively. Meat scraps, fish and fish bones, poultry (including small bones like chicken wings), shellfish meat, and dairy all process in the machine without issue.

The limitation is large, dense bones: beef marrow bones, large pork ribs, whole poultry carcasses. These take far longer than other scraps to break down and can put stress on the machine's mixing mechanism. Small bones (chicken wing bones, fish bones) are fine.

The aerobic process and carbon filter also manage the odor from meat and fish — which are among the most odor-generating scraps if composted anaerobically or simply dehydrated.

Q9. Can I put cooked food in it?

Yes — all types of cooked food. This includes:

• Cooked grains (rice, pasta, quinoa, oats)
• Cooked vegetables and legumes
• Cooked meat and poultry
• Mixed dishes (stir-fries, curries, soups, stews — in moderate amounts)
• Bread and baked goods
• Dairy and egg-based dishes (quiche, custard, sauces)
• Leftovers of any kind

The Reencle accepts cooked food without restriction that outdoor compost piles have. Outdoor piles typically exclude meat and cooked food because they attract pests, create odor problems, and can introduce pathogens in unmanaged systems. Reencle's enclosed, controlled environment eliminates all three concerns.

One practical note: Drain excess liquid from soups and sauces before adding. A small amount of liquid is fine; a large volume of liquid all at once can temporarily overwhelm moisture balance.

Q10. What can't I put in it?

The inputs to avoid fall into a few clear categories:

Mechanical limitations:

• Large, dense bones (beef femur, large pork ribs, whole poultry carcasses)
• Hard shells: lobster, crab, large clam and mussel shells, avocado pits, peach and mango stones
• Non-food items: plastic packaging, rubber bands, foil, twist ties

Biological limitations:

• Very large volumes of liquid at once (large bowls of soup broth, significant cooking oil)
• Highly chemically treated or synthetic materials (artificial sweeteners in very large amounts, heavily processed food additives — in normal household quantities these are fine)

Not designed for:

• Yard waste, lawn clippings, cardboard, large amounts of paper — the Reencle is sized and designed for food scraps, not garden waste

Everything that would normally go into a kitchen food scrap bin — vegetables, fruit, cooked food, meat, fish, dairy, eggs, bread, coffee, tea — the Reencle accepts.

Q11. What does the output look and smell like?

The output removed from the Reencle is a dark, dry to slightly damp, crumbly material with a volume significantly reduced from the original food scraps (typically 70–90% volume reduction). It resembles dark potting soil or finished compost.

Smell: The output from the machine has an earthy, soil-like smell — similar to healthy compost. It should not smell rotten, sour, or like food waste. If it has a very strong odor, it may need more curing time before use.

After the recommended 3-week or longer curing period (spreading in an open container and allowing it to finish stabilizing), the output is dark, dry, and nearly odorless — essentially indistinguishable in appearance from quality compost.

Q12. How do I use the output in my garden?

After curing for 3 weeks or more, Reencle output can be used in several ways:

As a soil amendment: Mix 10–20% by volume into garden bed soil or potting mix before planting. For established beds, work 1–2 cm into the top layer.

As a top dressing: Apply a 1–2 cm layer around the base of plants and water in. This feeds soil organisms and slowly releases nutrients to plant roots.

For potted plants: Mix 10–15% into potting soil when repotting, or top-dress with a thin layer for established container plants.

For raised beds: Mix generously into bed soil each season as an organic matter amendment — 15–20% by volume is appropriate for vegetable beds.

The output from Reencle is rich in organic matter and beneficial microorganisms. Unlike synthetic fertilizers, it does not provide a large immediate nutrient spike — it improves soil structure and microbial activity over time, which supports long-term plant health.

Q13. How much electricity does it use?

Reencle consumes approximately 1 kWh per day under typical operating conditions — comparable to a laptop running continuously or a small lamp left on all day.

At average US electricity rates (approximately $0.16 per kWh as of 2024), this translates to roughly $4–5 per month in electricity cost. This is less than most households spend on trash bags to dispose of food waste.

The machine runs its heating and mixing systems on a managed cycle rather than at full power continuously, which contributes to this relatively low energy profile.

Q14. How often do I need to replace the filter?

Reencle uses a carbon (activated charcoal) filter to capture volatile compounds before they exit the machine. Under normal operating conditions with typical household food waste, the filter should be replaced approximately every 3–6 months.

Factors that reduce filter life:

• Frequent addition of strong-smelling inputs (fish, fermented foods, strong cheeses)
• High-volume use (large family, frequent food waste generation)
• High ambient humidity (the filter absorbs moisture along with volatiles)

Signs the filter needs replacement:

• A noticeable food-like or organic odor becomes detectable near the machine
• The machine's own indicator (if applicable to your model) signals replacement

Replacement filters are available directly from Reencle. The replacement process is simple and requires no tools.

Q15. How do I clean it?

The Reencle's interior — where the microbial culture lives — does not need to be cleaned or disinfected. Cleaning the interior would remove or damage the microbial community that makes the machine work. The microorganisms manage the interior environment naturally.

What does need occasional attention:

• The exterior housing: Wipe down with a damp cloth as needed. Avoid harsh chemical cleaners near the air vents.
• The lid and seals: Wipe clean to prevent buildup. A food-safe, mild soap is fine.
• The mixing paddles and interior walls (if removing output): Wipe down any visible buildup from the walls above the active material level with a damp cloth. Do not use bleach or antibacterial products inside the chamber.

The machine is designed for continuous operation with minimal maintenance beyond filter replacement.

Q16. What happens if I go on vacation?

If you're away for less than 2 weeks, the Reencle can be left running without intervention. The microbial community is resilient and will remain active without fresh food input. The machine will continue cycling. When you return, resume adding food scraps normally.

If you're away for 2–4 weeks: Leave the machine running. You may optionally add a small amount of carbon-rich material (a few pieces of dry bread, a handful of oats) before you leave to give the microbes a substrate to work with during the period of low input. Again, the culture will remain viable.

If you're away for more than a month: Leave the machine running if possible. The microbial community can persist in a low-activity state with minimal or no fresh input for extended periods. If you need to turn the machine off (for power or travel reasons), add a small amount of dry carbon material before shutting down and allow the interior to dry slightly. When you return, restart the machine and resume feeding; the culture typically reactivates within a few days.

Q17. How long does the microbial culture last?

The resident microbial culture in Reencle is designed to be self-sustaining for the life of the machine under normal operating conditions.

The culture is self-replenishing — as long as you continue adding appropriate food scraps, the microorganisms reproduce and maintain their population. The culture does not need to be periodically replaced in the way a yogurt starter or sourdough starter would.

Factors that can stress the culture:

• Extended periods without food input (the culture remains viable but may need a few days to return to full activity)
• Very large amounts of strongly antimicrobial substances (extremely large amounts of raw garlic, strong vinegar, antibacterial agents). Normal household quantities of these foods are fine.
• Power outages lasting more than a few days (the heating and aeration systems maintain the culture's preferred environment)

In normal household use, the microbial culture requires no active maintenance beyond continuing to feed the machine.

Q18. How is Reencle different from other electric composters on the market?

This is the question that gets to the core of what distinguishes Reencle from its most visible competitors.

The mechanism:

The output distinction matters: Some competitors market their output with compost-adjacent language, but dehydration-based devices do not put food scraps through biological decomposition. Applied to soil, that material continues to break down — a process that can temporarily draw nitrogen from the soil. Reencle output, having already been biologically processed, does not have this effect after curing.

Dehydration-based devices with additional modes: Some competitors offer advanced modes designed to support biological breakdown using specific additives. These produce a more compost-like output, but require longer run times and proprietary products. Reencle's biological processing is continuous and does not require additives.

Subscription-based models: Some competitors operate as a subscription service focused on food waste volume reduction, with dehydrated output collected and composted externally. This is a different service model rather than a home composting solution.

Q19. Is it worth the price?

Whether Reencle is worth the investment depends on what you're trying to accomplish:

Reencle makes strong sense if:

• You generate significant food waste from meat, fish, or cooked food that cannot go into standard outdoor compost
• You want to produce actual garden-usable compost output rather than simply reducing waste volume
• You don't have space or conditions for outdoor composting (apartment, no yard, cold climate)
• Odor-free, low-maintenance operation matters to you
• You're replacing food waste disposal costs (bags, municipal food waste bin fees)

Where to be realistic:

• The upfront cost is significant. The payback is primarily environmental and qualitative (better garden output, less waste) rather than strict financial return.
• You need a 3-week or longer curing step before the output is ready to use. It's not instant finished compost.
• It requires counter or cabinet space.

For households that currently send food waste to landfill due to lack of outdoor composting options, Reencle offers a meaningful alternative. For households already effectively composting outdoors, the primary advantage is convenience and year-round operation including meat and cooked food.

Q20. Where should I place it in my home?

The Reencle can be placed on a countertop, kitchen island, pantry shelf, or utility area. It requires:

• A standard electrical outlet (no special voltage requirements)
• Adequate ventilation — do not enclose it in a sealed cabinet with no airflow
• A stable, flat surface
• Reasonable proximity to where you generate food scraps (to make adding scraps convenient)

Best placements:

• Kitchen counter near the sink or food prep area
• Kitchen island
• Open pantry shelf with ventilation
• Mudroom or utility room adjacent to the kitchen

Avoid:

• Sealed cabinets with no airflow (the machine requires air circulation for its filtration system)
• Outdoor or unheated spaces — the machine is designed for indoor use at room temperature
• Direct sunlight for extended periods

The machine's footprint is comparable to a large coffee maker or bread machine. Most users find a kitchen counter position most convenient for regular use.

Practical Takeaways

• Reencle uses biological decomposition — live microorganisms — not just heat. The output is fundamentally different from dehydrated food waste.
• It accepts meat, fish, dairy, cooked food, and most kitchen scraps without restriction on these categories.
• Under normal use, it does not produce noticeable odor. The filter manages volatiles; the aerobic process prevents the compounds responsible for rotten smell.
• Allow output to cure for 3 weeks or more before applying to plants.
• Filter replacement every 3–6 months is the primary ongoing maintenance.
• The microbial culture is self-sustaining and does not need to be replaced.
• Electricity cost is approximately $4–5/month at average US rates.
