- 1DASRI = 15-20% of volume but 50% of a hospital’s waste bill.
- 230 to 50% of yellow bins contain mis-sorted waste that auditing and training can address.
- 3€500 to €1,000/tonne versus €150 to €200 for household waste: a factor of 4 to 6.
- 4Audit + training = -15 to 25% in volumes within a few months, a measurable gain.
DASRI: why it is the perfect CSR lever in a healthcare institution
We start with a surprising figure: treating a tonne of DASRI costs €500 to €1,000 excl. VAT, compared with €150 to €200 for a tonne of ordinary waste. A factor of 4 to 6. And yellow bins consistently contain 30 to 50% of waste that is not DASRI - unsoiled packaging, clean gloves, paper. The result: thousands of euros and tonnes of CO₂ literally go up in smoke every year (to put these orders of magnitude in context).
For a CSR manager in a healthcare institution, few subjects tick so many boxes. DASRI combines regulatory compliance (Public Health Code + digital traceability on Trackdéchets), quantifiable savings (several tens of thousands of euros at a university hospital), direct decarbonisation (−13 tCO₂e for a 500-bed hospital), and above all a level of team engagement few projects generate - because results become visible within a few weeks.
This guide provides what you need: the 2026 regulations, actual costs, a comparison of the three treatment routes, the causes of mis-sorting and a three-step action plan that pays off from the first month.
1What DASRI is (and what it is not)
DASRI = healthcare waste presenting infectious risks. Article R.1335-1 of the Public Health Code defines it precisely, and ADEME estimates the annual volume at 170,000 tonnes in France - hospitals, clinics, private practices, laboratories, patients treating themselves.
What counts as DASRI (yellow bin or rigid sharps container):
- All sharp equipment: needles, scalpels, blades, capillaries
- Any waste soiled with blood or a biological fluid (swabs, dressings, tubing)
- Expired blood products and human anatomical waste
- Waste presenting a proven infectious risk (group 3 and 4 agents)
What does not count as DASRI (black bag, DAOM):
- Packaging of medical devices that is unopened or unsoiled
- Clean examination gloves removed after a non-contaminating procedure
- Paper, cardboard, packaging plastics from care departments
- Food leftovers and cleaning waste outside risk areas
Waste produced during care is not automatically DASRI. It only becomes DASRI if it has been in contact with blood, a biological fluid or an infectious agent - or if it is a sharp. This is precisely the distinction most healthcare staff apply incorrectly: the instinct to put it in the yellow bin when in doubt is deeply ingrained, understandable on a human level, and very costly.
2What the regulations say in 2026
The framework: Articles R.1335-1 to R.1335-14 of the Public Health Code, the Order of 7 September 1999 (storage), the Decree of 30 June 2000 (incineration). The founding principle: producer responsibility. An institution producing DASRI is responsible for its disposal from end to end - subcontracting does not remove legal responsibility.
In practice, three obligations are non-negotiable:
- Sorting at source: DASRI must be separated from other waste as soon as it is produced, in approved containers - yellow bins for soft waste, rigid sharps containers for sharp objects.
- Compliance with disposal deadlines: an institution producing more than 100 kg of DASRI a week must have it collected at least every 72 hours (the deadline varies from 72h to 7 days depending on volumes).
- Traceability: each collection has a waste consignment note (BSD) accompanying the waste from producer to treatment centre, which must be retained for three years.
Two recent developments. The new ministerial guide (July 2025, first revision since 2009) clarifies sorting instructions and encourages alternatives to incineration. And Trackdéchets (the government platform) is open to DASRI: pending a regulatory text announced for 2027, the Directorate-General for Health authorises digital consignment notes on the platform, tracing every DASRI movement from production to treatment.
3How much DASRI treatment costs
The orders of magnitude to remember:
The hidden cost of mis-sorting: a 500-bed hospital
What mis-sorting really costs, in euros and carbon
- DASRI incineration: €500 to €1,000 excl. VAT/tonne (national average €854 excl. VAT, DGOS figure)
- DAOM (ordinary waste): €150 to €200 excl. VAT/tonne
- Difference: a factor of 4 to 6 - each mis-sorted kilogram costs €0.65 to €0.85 more than necessary
- Hidden costs: approved containers, dedicated collection, refrigerated storage beyond 72h
A concrete example: a 500-bed hospital, 60 tonnes of DASRI a year. Treatment bill: €30,000 to €60,000 (compare with the cost of a Bilan Carbone®). With a mis-sorting rate of 35% - a low average - the same hospital sends 21 tonnes of ordinary waste through the DASRI route. Additional cost calculation: 21 × (800 − 175) = €13,000/year in unnecessary treatment, and 13.3 tCO₂e emitted for nothing. At a university hospital handling 500 tonnes a year, potential savings exceed €100,000.
4The carbon footprint of a tonne of DASRI
Beyond the financial cost, DASRI carries a carbon cost that has a substantial weight in a healthcare institution’s assessment. High-temperature incineration of a tonne of DASRI emits on average 0.7 to 1.1 tonnes of CO₂e (ADEME Base Empreinte 2025), equivalent to 5 to 7 Paris-Marseille flights. For a university hospital treating 600 tonnes of DASRI a year, that means 400 to 660 tonnes of CO₂e annually - a source structurally present in every hospital BEGES.
DASRI: 3 treatment routes compared
Emissions, cost and logistical constraints
Alternative routes change the picture. Autoclaving (thermal decontamination) emits around 300 kgCO2e per tonne treated, or around 3 times less than incineration. Chemical decontamination lies at an intermediate level (0.3 to 0.5 tonnes CO₂e/tonne). The determining factor: the process’s energy consumption and the site’s electricity mix.
But the most effective lever remains upstream, rather than downstream. Reducing volumes by 30 to 50% through sorting mechanically divides the carbon footprint by 1.5 to 2. This is the winning combination: fewer tonnes treated + a lower-carbon route = up to 70% reduction in the waste source’s carbon footprint at a well-organised institution.
5Incineration, autoclaving, decontamination: which route to choose
Incineration still treats 80% of DASRI in France. But two alternatives exist:
Actual contents of a yellow DASRI bin
30 to 50% of the contents should not be there
- Incineration: 934 kgCO₂e/tonne, €500-€1,000 excl. VAT/t - accepts all DASRI without exception
- Autoclaving: ~300 kgCO₂e/tonne - three times less emitting, but excludes anatomical and cytotoxic waste
- On-site decontamination: ~250 kgCO₂e/tonne - eliminates transport, profitable from 5 t/year of DASRI suitable for decontamination
Incineration: the default route
Combustion at a minimum of 850°C in an approved centre. The only route accepting all types of DASRI - including anatomical and cytotoxic waste. Also the highest-emitting: 934 kgCO₂e/tonne, €500 to €1,000 excl. VAT/t, plus transport to a sometimes distant centre.
Autoclaving: divide by three
Steam at 134°C for 18 minutes, followed by shredding. The waste loses its infectious character and enters the ordinary waste route: ~300 kgCO₂e/tonne, three times less than incineration. Limitation: unsuitable for anatomical, chemical or cytotoxic waste.
On-site decontamination: eliminate transport
An on-site decontamination unit (standard NF X30-503) combines shredding and autoclaving at 135°C. DASRI emerges inert, with a 65 to 80% reduction in volume and a footprint of around 250 kgCO₂e/tonne because transport is eliminated. Profitability threshold: 5 tonnes/year of DASRI suitable for decontamination - relevant from 300 beds. Pioneers: Foch hospital (Suresnes), GHT Caux-Maritime.
Incineration: 934 kgCO₂e/tonne. Autoclaving: 300. On-site decontamination: 250. Choosing the route makes a difference of a factor of three or four - to the footprint and the bill.
6Mis-sorting: why 30 to 50% of yellow bin contents should not be there
The most widespread problem - and the most profitable to correct. Hospital yellow bins consistently contain 30 to 50% of waste that is not DASRI: unsoiled packaging, clean gloves, paper, cardboard. Hôpital Privé de Dijon Bourgogne measured 48% mis-sorting in its first audit. This is representative.
Reduce DASRI volumes: the 3-step plan
From a rapid audit to on-site treatment - a progressive path
Three causes combine:
- The precautionary instinct: "when in doubt, put it in yellow" has become automatic for many healthcare staff - understandable on a human level, but very costly.
- Lack of targeted training: sorting protocols differ between an operating theatre, an outpatient consultation and a laboratory, but waste training is often generic and infrequent.
- Confusion between healthcare waste and DASRI: syringe packaging produced during care is not infectious waste unless it has been in direct contact with blood. The 2025 ministerial guide clarifies this distinction, but information takes time to reach departments.
7Reduce DASRI volumes in three steps
Three stages, in this order:
- Step 1 - Measure: a yellow bin characterisation audit, 1 week, almost no budget
- Step 2 - Train: short targeted training by department, signage, sorting leads
- Step 3 - Invest (if volumes justify it): on-site decontamination unit, above 5 t/year
The first two steps pay off from the first month. The third is a budget decision depending on volume - but generally achieves ROI in 3 to 5 years.
Step 1 - The waste characterisation audit
Weigh and characterise waste streams over a week, in two or three contrasting departments (operating theatre, inpatient care, outpatient consultation). Open yellow bins, sort, weigh, calculate each department’s mis-sorting rate and associated additional cost. One week, little budget, but this provides the factual basis for everything that follows. Without this measurement, the rest is guesswork.
Step 2 - Targeted training by department
Short sessions (30 min), adapted to the context: operating theatres do not have the same waste as outpatient consultations. The most effective tool: a concrete "yellow or black?" photograph with examples from the audit. Appoint sorting leads by department, update signage. Result: −15 to 25% in DASRI volumes within a few months. For an institution starting with 48% mis-sorting, such as Hôpital Privé de Dijon Bourgogne in its first audit, the maximum theoretical gain is approximately dividing volumes by 2.
Step 3 - Invest in the treatment route (if volumes justify it)
Above 5 tonnes/year of DASRI suitable for decontamination, an on-site decontamination unit becomes profitable. Below that, switching to a provider offering autoclaving is a useful intermediate lever. In every case, a volume monitoring dashboard sustains the gains.
To go further - DASRI represents only a small share of a hospital’s total carbon footprint, with the whole "waste and services" category accounting for around 4% of healthcare emissions according to The Shift Project - a hospital BEGES gives the overall picture. Most of the footprint comes from purchases: medicines and medical devices. And for more structural levers, such as moving from single-use to reusable, LCA enables decisions based on figures.
A sorting audit + a training campaign = 15 to 25% less DASRI within a few months. This is the quickest and most profitable lever for a healthcare institution.
8Key takeaways
Regulations, costs, carbon footprint: everything converges. Better sorting means achieving compliance, saving money and decarbonising at the same time. A rare lever ticking all three boxes.
- Regulations are strict and tightening: mandatory sorting at source, disposal deadlines (72h for large producers), traceability through consignment notes, on paper or digitally on Trackdéchets, pending mandatory digitalisation announced for 2027.
- Treatment costs are 4 to 6 times higher than for ordinary waste: €500 to €1,000 excl. VAT per tonne versus €150-€200 for DAOM. Each kilogram of false DASRI brings a direct, measurable additional cost.
- 30 to 50% of yellow bin contents is not DASRI: it is mis-sorting, addressed through an audit and training campaign. Result: -15 to 25% in volumes within a few months.
- Three routes exist: incineration (934 kgCO₂e/t), autoclaving (300 kgCO₂e/t), on-site decontamination (250 kgCO₂e/t). Choosing the route divides the footprint - and the bill - by three or four.
Audit + training = stronger compliance and immediate savings. Incorporated into a hospital BEGES, this is often a decarbonisation plan’s first concrete success - the kind of result that brings teams on board.
