Pathology Laboratory Waste Incinerators
Cultures, plates, specimen containers and blood tubes from pathology and microbiology, destroyed in-house.
A diagnostic laboratory produces small quantities of waste that nobody wants to move: cultures, plates, specimen pots, blood tubes and the plastics that touched them. It is awkward to consolidate, expensive to consign and slow to collect. Destroying it in the same building it was cultured in is the shortest route it will ever take.
Four Models,
One Solution
The entry point to the LitBurn range. A 3.3 m³ primary chamber and three burners give continuous 125 kg/h destruction in a footprint that fits a standard yard bay, which makes it the usual choice for a single-site operator replacing skip hire rather than a multi-site waste contract.
The most specified unit in the range. Chamber volume rises to 5.5 m³ for 250 kg/h continuous throughput while the external width grows by only 230 mm over the LBI-125, so sites that outgrow the smallest unit rarely have to rework the slab or the building line.
A 9.6 m³ chamber — nearly double the LBI-250 — for medium-scale industrial waste destruction. At this size most operators pair the unit with heat recovery, because the thermal output during a full shift is large enough to displace a dedicated water heater.
The largest LitBurn: a 16.2 m³ chamber running 500 kg/h continuously. Specified where waste arrives faster than a batch unit can clear it — large manufacturing sites, industrial estates, and operators consolidating several smaller waste contracts onto one machine.
Which Model
Fits Your Volume
Pick a model to see what it clears in a day of laboratory & pathology waste.
A hospital pathology department sharing the unit its infectious stream justified — two hours a week covers the laboratory output.
18 01 03* for infectious, 18 01 06* for chemical
Infectious laboratory waste codes as 18 01 03*; waste carrying hazardous chemicals or fixatives is 18 01 06*. Both belong in the permit application if both are produced, and the second one is the line that is most often forgotten on a hospital application.
Containment rules sit upstream
What may leave a laboratory, and in what state, is decided by the containment level and the local biological safety arrangements. The unit is the disposal step after that decision — it does not license material out of a room it may not leave.
Declare the halogenated condition
Laboratory plastics and packaging can push a run past 1% halogenated organic content, which sets the secondary chamber minimum at 1,100°C. Where laboratory waste shares a unit with a PVC-heavy clinical stream, declare the higher condition once and be done.
Confidentiality is not a waste control
Patient-identifiable labels and request forms are destroyed with the specimen, and that is a real benefit — but the waste classification is decided by hazard, not by sensitivity. Both requirements have to be satisfied, and only one of them is the permit's business.
Why Burn It
On Site
4 things change on the day this stream stops leaving the site.
Small volumes are the worst ones to consign
A few boxes a week is too little to interest a haulier and too much to hold. It is the stream where collection charges are worst per kilogram and where a missed pickup has the most disproportionate effect on a working laboratory.
Cultures are destroyed the same day they are finished with
Plates and broths sitting in a store are a growing population in a box. Destroying them on the day the work closes removes the hold entirely rather than managing it with a fridge and a schedule.
Specimens never leave the building
Patient-identifiable material on tubes, pots and request forms stops being a confidentiality question the moment it stops travelling. Destruction in-house closes that exposure alongside the clinical one.
Mixed plastic and glass go in one route
Pots, tubes, tips and slides do not separate usefully and are not recyclable once contaminated. One permitted route for the whole bench output is simpler than three partial ones.
Dual-chamber unit, 1,100°C capable
Primary chamber running 850–1,200°C with a secondary chamber holding flue gas above 850°C for two seconds. Clinical charges are PVC-rich — IV bags, giving sets, suction tubing, sterile packaging — so where the stream carries more than 1% halogenated organic content the secondary minimum rises to 1,100°C, and the unit holds it as built rather than as an upgrade.
Front dual-door loading
The LBI range is charged through a front dual door at floor level. Wheeled 770-litre clinical carts, rigid-bodied sharps bins and red-lidded anatomical containers go in at the height they arrive at, which is what keeps the last handling step in a clinical waste route a push rather than a lift over a rim.
What Ships
With The Unit
Identical whichever stream it is specified for. The operating procedure changes; the machine does not.

IP6X control panel with cycle logging
PLC control with chamber thermocouples, interlocked charge door and a time-stamped temperature record per run. For clinical waste that record is what turns a claim of destruction into evidence of it — the condition an infection control audit or a permit compliance check asks to see.
Burner set and fuel train
Configured for natural gas, LPG, diesel, biofuel or hydrogen, with three burners across the LBI range. Fuel choice is a site decision; the combustion condition is identical whichever is specified. Wet loads — anatomical waste, suction liners, fluid-heavy dressings — draw more burner time, not a different machine.
Coretex refractory lining
Monolithic castable lining rated for the full temperature range and for sustained running at the top of it. Replaceable in service rather than requiring the shell to be scrapped with it, which matters on a unit running shifts against a daily arisings curve rather than single burns.
Stack, dispersion data and commissioning
Stack supplied to the height your site-specific dispersion assessment calls for — hospital sites usually carry the tightest one on this list, with wards, intakes and neighbours all inside the assessment — plus the emissions data pack the permit application references, on-site commissioning, a witnessed first run and operator training.
How One Burn Runs,
Start To Finish
One run is one countable event, reconciled against a manifest and evidenced by a time-stamped temperature log.
One Cycle,
Start To Finish
Adds 18 01 03* for infectious laboratory waste and 18 01 06* where hazardous chemicals or fixatives are present. Containment-level inactivation at the bench stays a laboratory duty — the unit is downstream of it, never instead of it.
Cultures that must be autoclaved before leaving the laboratory are autoclaved before leaving the laboratory. The incinerator is the disposal step after containment, and the containment rules are the laboratory's to apply.
Formalin, xylene, solvent-bearing residues and fixed specimens are a chemical question under 18 01 06*, not an infectious one. What may go in the charge is decided at the bench, where the person who knows what is in it is standing.
Rigid bins and sealed boxes go through the front dual door as they are. Nothing is decanted, and no bag is opened to confirm what was written on it.
Primary at 850–1,200°C with two-second secondary retention above 850°C, or 1,100°C where the run carries more than 1% halogenated organic content — laboratory plastics push a charge towards that line more often than bagged ward waste does.
Residue is 3–5% mineral ash with an inert glass and metal fraction from slides, tubes and tips. The run log and the container count close the record for the department.
What You Can Burn —
And What You Can't
One run takes the whole stream without pre-sorting. What must never enter it is a short, hard list.
Yes: accepted in a run
No pre-sorting between these
- Microbiology cultures and platesAgar plates, slopes, broths and culture vessels from diagnostic microbiology, inactivated first where the containment level requires it and charged in sealed rigid containers.
- Specimen containers and transport mediaUrine and faeces pots, sputum containers, swabs and transport media that have carried patient material — charged closed, never emptied.
- Blood, serum and sample tubesVacutainers, serum tubes and sample bottles from haematology, biochemistry and blood sciences, including the residual sample inside them.
- Slides, coverslips and small glasswarePrepared slides, coverslips and contaminated small glassware, collected in a rigid container. The glass fraction reports to the ash as inert residue.
- Contaminated consumables and plasticsPipette tips, tubes, racks, gloves and bench roll that carried patient material — the volume fraction of a laboratory stream and the reason chamber space matters.
- Point-of-care and screening cassettesUsed test cassettes, lateral flow devices and cartridges from ward and clinic testing, consolidated for destruction under the laboratory's own route.
No: never charged
Not a permit question — these stay out
- Bulk solvents, xylene and formalinA waste incinerator of this class is not a liquid injection plant. Bulk chemical goes to a licensed hazardous liquids route; only absorbed or containerised residues within the agreed scope are a question for the charge.
- Hazard Group 4 and Category A materialThe highest containment groups have their own inactivation and disposal regime under the containment level that holds them. That material does not cross a yard to reach a waste unit.
- Radioactive tracers and labelled wasteAnything bearing radionuclides from nuclear medicine or labelled assay work is controlled under radioactive substances legislation, decayed or disposed of under that regime rather than in a clinical charge.
- Cytotoxic-contaminated laboratory wasteWhere cytotoxic drugs are handled in the laboratory, that waste is 18 01 08* hazardous with its own permitted scope. It routes as cytotoxic waste on the pharmaceutical sector, not as general laboratory waste.
Can you legally burn laboratory & pathology waste on site?
Technically, yes: the chamber destroys almost everything on the accepted list at 850–1,200°C, and capability is rarely the constraint. Legally is a separate question. What your site is allowed to burn is set by your environmental permit from the Environment Agency, SEPA or NIEA and the waste codes written into it. The never-charged list is different again: those materials are out of scope for the unit or governed by a direction, and no permit wording brings them back in. Send us the codes you hold, or the ones you expect to apply for, and we will tell you which of this list they cover before anything is specified.

How This
Was Worked Out
250 kg a week against the LBI-125's 125 kg/h = about 2 hours of running. That is a quarter of a shift, which is why this stream is sized as an addition to the infectious waste the unit was bought for. Size the machine on the ward and theatre stream, then confirm the laboratory codes — 18 01 03* and any 18 01 06* — are named in the same permit. Adding a code at application costs nothing; varying a permit later does.

Laboratory & pathology waste Questions
Answered against the published figures for the models specified for this stream, not a generic range sheet.
Hospital laboratory waste is what diagnostic work leaves behind: microbiology cultures and plates, specimen containers, blood and serum tubes, swabs and transport media, pipette tips, plastics and the disposable consumables that carried any of it. Most of it is infectious under 18 01 03*; some carries hazardous chemicals or fixatives and codes as 18 01 06*, and the difference decides the route. This is a diagnostic stream rather than a research one. Pharmaceutical R&D laboratory waste — medicinal residues, chemical synthesis, formulation work — is specified separately on the pharmaceutical sector, because its exclusions and its permit lines are different even where the machine is the same. The unit sits downstream of the laboratory's own containment controls, never in place of them. Where the containment level or the local rules require cultures to be inactivated at the bench before leaving the laboratory, that step happens first — an incinerator in the yard does not change what may leave a Containment Level 3 room, and material at the highest hazard groups does not travel this route at all. The volumes are small. A hospital pathology department might produce a couple of hundred kilograms a week, which is under two hours on the smallest LitBurn. That is the honest reason this stream almost never buys a machine by itself — it rides on the unit the infectious stream justified, with its own codes named in the same permit.

Adding a code at application costs nothing; varying a permit later does.
That depends on the containment level and your own biological safety arrangements, not on the incinerator. Where the rules require inactivation before material leaves the laboratory, it happens first — the unit is the disposal step downstream. Where they do not, sealed containers are charged as they are.
This is diagnostic pathology and microbiology: patient specimens, cultures and the consumables around them. Pharmaceutical R&D waste is medicinal and chemical — synthesis residues, formulation trials, stability samples — with different exclusions and different permit lines. It is specified on the pharmaceutical sector for that reason.
Not as ordinary laboratory waste. Fixative makes the container a hazardous chemical waste question under 18 01 06*, and bulk liquid chemistry belongs to a licensed liquids route rather than this class of unit. Agree the containerised cases explicitly at specification rather than deciding them at the door.
Almost never on its own. A couple of hundred kilograms a week is under two hours on the smallest LitBurn. The sensible route is to size the machine on the infectious ward and theatre stream and add the laboratory codes to the same permit, which costs nothing at application stage.
They report to the ash as inert residue with no recoverable form. Slides, coverslips and tubes should still be collected in a rigid container rather than a bag — the sharps handling logic applies to broken glass whether or not the container carries a sharps label.
Yes, as a side effect worth having: patient-identifiable pots, tubes and forms are destroyed inside the building rather than travelling in someone else's vehicle. It does not change the waste classification, which is decided by hazard — but it does remove a real exposure that a collection route leaves open.
