What is a compost machine?

A compost machine processes suitable organic waste biologically under controlled conditions. Grebotics S72 shreds accepted material and processes it in a single chamber. Temperature, moisture, gas and heat-balance data guide AI-assisted biological phase control. The 250, 500 and 1000 L models are developed for industrial use and manufactured at Sakarya Teknokent, Türkiye.

NATURAL PROCESS, OPTIMISED CONDITIONS

Bringing months of transformation down to days.

Processes in windrow compost facilities can extend to around six months depending on feedstock and site conditions. We accelerate transformation while preserving natural biological methods, optimising bacterial life cycles by managing temperature, moisture, oxygen and mixing together.

An active composting period that can be reduced to 72 hours through bacterial life-cycle optimisation under suitable feedstock and process conditions.

These times refer to the active composting stage. Necessary maturation, stability and quality assessment are planned separately for the material and its intended use.

02 / THE RECOVERY WORKFLOW

From waste to resource, step by step.

A well-planned workflow comes first. Collection, processing and output assessment are parts of one system.

Separate at source01

Separate at source

Suitable organic residues are collected separately in kitchens and service areas, removing packaging and foreign materials.

Prepare for processing02

Prepare for processing

The internal double-shaft shredder prepares organic material for processing. Collection and feeding follow the facility’s daily workflow.

Controlled transformation03

Controlled transformation

Sensor data identifies the biological phase; temperature, air and mixing conditions are managed to support microbial activity.

Recover resources04

Recover resources

Output quality and suitability are assessed. Recovery is completed with a plan for the material’s next use.

03 / AI-ASSISTED PROCESS CONTROL

More than heating. Managing a biological process.

GreBotics S72 does not operate from a single temperature value. It evaluates sensor data and heat balance together, identifies the bacterial phase and manages conditions that support the microbial life cycle.

01 / MEASUREMENT

Process gases

Gas readings are assessed alongside biological activity.

Compost temperature

Temperature changes in the organic material are monitored.

Chamber temperature

The relationship between material and its process environment is tracked.

Moisture

Water balance for biological conversion is evaluated.

02 / IDENTIFY THE PHASEAI-assisted control

Sensor data + heat balance + process changes

03 / MANAGE CONDITIONS

Aeration

Air management is considered together with biological activity and heat balance.

Heat management

The difference between supplied and removed heat is interpreted alongside process data.

Mixing arrangement

Operating parameters are managed according to material processing conditions.

Continuous feedback: the process response is measured again and operating parameters are managed accordingly.
BACTERIAL LIFE CYCLE

Every phase has different needs.

The aim is not to keep the chamber continuously hotter. The system interprets temperature and moisture alongside gas data and heat exchange, basing decisions on changes in the biological process rather than one instantaneous reading.

Natural biological methods are preserved. With suitable feedstock and operating conditions, bacterial life-cycle optimisation can reduce active composting to 72 hours. Curing and suitability for use are assessed separately.

  1. 01

    Biological initiation

    Microorganisms begin using readily degradable organic compounds, initiating biological activity.

  2. 02

    Heating and growth

    Microbial activity increases heat production. Changing temperature, moisture and gas data are evaluated together.

  3. 03

    Intensive active conversion

    Heat-adapted microorganisms become active. Aeration, heat and mixing conditions are managed to support biological activity.

  4. 04

    Continued decomposition

    Biological activity changes as readily degradable nutrients decline. The control system adjusts operating parameters to the changing process requirements.

  5. 05

    Cooling and balancing

    Heat production decreases, and microorganisms active at lower temperatures become prominent again.

  6. 06

    Transition to curing

    Following active processing, the output proceeds to curing and quality assessment as required for its intended use.

The stages do not follow fixed time intervals; they vary with feedstock composition and process conditions. The AI-assisted control system evaluates sensor data to manage operating conditions at each stage. Curing is assessed separately from the stated active composting period.

FROM MACHINE TO CLOUD

A clearer view of each operating month.

The cloud data collection system brings machine process and operating data into monthly reports. Indicators include energy use, process data and estimated carbon benefit. Measured energy and calculated carbon estimates are distinguished.

First year included

All data connections and monthly reports are free in the first year with machine purchase.

DRYING AND BIOLOGICAL CONVERSION

Smaller waste does not automatically mean compost.

Heating and grinding can remove water and quickly reduce mass. This alone does not demonstrate conversion into biologically stable compost.

Explore drying versus composting ↗
01

Dehydration

The main function is water removal. Dry output can be feedstock for subsequent composting; appearance does not establish maturity.

02

The Grebotics approach

Sensor data and heat balance inform biological phase assessment. AI manages process conditions that support bacterial life cycles.

GREBOTICS / COMPOST MACHINE GUIDE

Understand the technology and operating conditions.

Technical selection, operation and reporting information for businesses considering compost machines.

How does a compost machine work?

Suitable organic residues are separated, prepared by the shredder and processed biologically in a single chamber. GreBotics S72 evaluates temperature, moisture, gas and heat-balance data together to manage phase-specific parameters.

What does 72 hours mean?

It describes active composting that can be reduced to 72 hours under suitable conditions through bacterial life-cycle optimisation. Feedstock and feeding schedules affect the result. Curing and quality assessment are planned separately before use.

Are 250, 500 and 1000 litres daily throughput?

No, these figures are single-chamber volumes. AI determines when each cycle is complete, and in our experience a cycle averages 72 hours. Average daily processing is therefore about 80 L for the 250 L model, about 165 L for the 500 L model and about 330 L for the 1000 L model. Feedstock and process conditions affect the duration.

How is a compost machine priced?

We prepare your quotation around waste quantity, site conditions and equipment needs. Our pricing page explains model selection, installation and service options.

How much electricity does the compost machine use?

Consumption depends on the feedstock. In our experience, average draw is about 30% of installed power: about 2.4 kW for the S72L250F, 4.5 kW for the S72L500F and 7.5 kW for the S72KL1F. Actual energy use is measured in the cloud system and shown in monthly reports.

What does the data service include?

Access process data, energy use and estimated carbon benefit indicators through the cloud. All data connections and monthly reports are free for the first year with machine purchase.

Does the machine cause odour or noise?

The S72 series is designed to run odour-free without a flue, using activated carbon filters, water filters and a deodoriser. Noise is at most 85 dB, which is taken into account in placement planning.

Can fresh waste be added every day?

No. The machine works in batches: the chamber is loaded at the start of a cycle, nothing is added during the cycle, and it is discharged at the end, roughly every 72 hours. No operator tasks are needed other than loading. Holding waste between cycles is planned at commissioning.

Are carbon-rich materials or additives needed?

Feedstocks differ in water, carbon and nitrogen balance. Structural material and mixture requirements are assessed for the actual input. The mixture is adjusted to the water, carbon and nitrogen balance of the feedstock.

Which materials must be excluded?

Remove glass, metal, plastic and packaging. Exclude hard materials outside the specification, such as wood, bovine bones and coconuts. Follow the model procedure for acceptable food waste and size limits.

How can the output be used?

Volume is reduced by 70–80%. The output can be used in gardens and landscaping, and as a soil improver after curing. Any curing and quality assessment needed for the intended use are planned separately.

What do the warranty and service cover?

Machines carry a standard 2-year warranty against manufacturing defects. An optional annual maintenance agreement and an optional fully extended warranty that also covers user error are available. We provide remote support and on-site visits throughout Türkiye.

What payment options are available?

We offer foreign-currency-based leasing and 12 interest-free instalments. The payment plan that suits you is agreed at the quotation stage.

Where is the machine made?

The S72 series is a domestically produced technology product, manufactured at Sakarya Teknokent, Türkiye. It was developed within a project approved by the Turkish Ministry of Industry and Technology.
