A. INTRODUCTION:

A Common Bio-medical Waste Treatment Facility (CBWTF) is a set up where bio-medical waste, generated from a number of healthcare units, is imparted necessary treatment to reduce adverse effects that this waste may pose. The treated waste may finally be sent for disposal in a landfill or for recycling purposes. Installation of individual treatment facilities by small healthcare units requires comparatively high capital investment. In addition, it requires separate manpower and infrastructure development for proper operation and maintenance of treatment systems. The concept of CBWTF not only addresses such problems but also prevents proliferation of treatment equipment in a city. In turn it reduces the monitoring pressure on regulatory agencies. By running the treatment equipment at CBWTF to its full capacity, the cost of treatment of per kilogram gets significantly reduced. Its considerable advantages have made CBWTF popular and proven concept in many developed countries.

CBWTF as an option has also been legally introduced in India. The Bio-medical Waste (Management & Handling) Rules, 1998, gives an option to the bio-medical waste generator that such waste can also be treated at the common bio-medical waste treatment facility. The Second Amendment of the Rules in June, 2000, further eased the bottleneck in upbringing the CBWTF by making Local Authority responsible for providing suitable site within its jurisdiction. The concept of CBWTF is also being widely accepted in India among the healthcare units, medical associations and entrepreneurs.

In order to set up a CBWTF to its maximum perfection, care shall be taken in choosing the right technology, development of CBWTF area, proper designing of transportation system to achieve optimum results etc. These key features of CBWTF have been addressed in the following sections and will form the guidelines for the establishment of CBWTFs throughout the country.

B. LOCATION

A CBWTF shall be located at a place reasonably far away from residential and sensitive area so that it has minimal impact on these areas. The CBWTF shall be located as near to its area of operation as possible in order to minimize the travel distance in waste collection, thus enhancing its operational flexibility. The location shall be decided in consultation with the State Pollution Control Board (SPCB)/Pollution Control Committee (PCC).

C. LAND REQUIREMENT

Sufficient land shall be allocated for CBWTF to provide all requisite systems. It is felt that a CBWTF will require minimum of 1 acre land area. So, preferably, a CBWTF be set up on a plot size of not less than one acre.

D. COVERAGE AREA OF CBWTF

In any area, only one CBWTF may be allowed to cater up to 10,000 beds at the approved rate by the Prescribed Authority. A CBWTF shall not be allowed to cater healthcare units situated beyond a radius of 150 km. However, in an area where 10,000 beds are not available within a radius of 150 km, another CBWTF may be allowed to cater the healthcare units situated outside the said 150 km.


E. TREATMENT EQUIPMENT

As per the provisions of Bio-medical Waste (Management & Handling) Rules, waste falling in most of the categories can be treated in systems based on non-burn technologies. Such waste account for about 90% of the total waste streams in a healthcare unit. In the brain storming session held during the workshop at Hyderabad (February 25-26, 2003), it was unanimously decided that the CBWTF should emphasize more on non-burn technologies. It is mandatory to impart incineration/deep burial (depending upon the population of town) to anatomical and other types of waste falling under categories 1 and 2. Therefore, an incinerator of adequate capacity to cater only categories 1 and 2 waste shall be installed. (If secured landfill is not available, category 5 may also be incinerated.)
The wastes falling under category 5 i.e. discarded medicines, cytotoxic drugs and category 10 i.e. chemical wastes (solids) can be disposed in a secured landfill.
A Common Bio-medical Waste Treatment Facility (CBWTF) shall have following treatment facilities:

• Incineration:
It is a controlled combustion process where waste is completely oxidized and harmful microorganisms present in it are destroyed/denatured under high temperature.
The guidelines for "Design & Construction of Bio-medical Waste Incinerators" prepared by CPCB shall be followed for selecting/installing a better bio-medical waste incinerator.

• Autoclaving/ Microwaving/ Hydroclaving:

Autoclaving is a low-heat thermal process where steam is brought into direct contact with waste in a controlled manner and for sufficient duration to disinfect the wastes. For ease and safety in operation, the system should be horizontal type and exclusively designed for the treatment of bio-medical waste. For optimum results, prevaccuum based system be preferred against the gravity type system. It shall have tamper-proof control panel with efficient display and recording devices for critical parameters such as time, temperature, pressure, date and batch number etc.

In microwaving, microbial inactivation occurs as a result of the thermal effect of electromagnetic radiation spectrum lying between the frequencies 300 and 300,000 MHz. Microwave heating is an inter-molecular heating process. The heating occurs inside the waste material in the presence of steam.

Hydroclaving is similar to that of autoclaving except that the waste is subjected to indirect heating by applying steam in the outer jacket. The waste is continuously tumbled in the chamber during the process.

Though chemical disinfection is also an option for the treatment of certain categories of bio-medical waste but looking at the volume of waste to be disinfected at the CBWTF and the pollution load associated with the use of disinfectants, the use of chemical disinfection for the treatment of bio-medical waste at CBWTF is not recommended.

• Shredder:
Shredding is a process by which waste are deshaped or cut into smaller pieces so as to make the wastes unrecognizable. It helps in prevention of reuse of bio-medical waste and also acts as identifier that the waste have been disinfected and are safe to dispose off. A shredder to be used for shredding bio-medical waste shall confirm to the following minimum requirements:

1. The shredder for bio-medical waste shall be of robust design with minimum maintenance requirement.
2. The shredder should be properly designed and covered to avoid spillage and dust generation. It should be designed such that it has minimum manual handling.
3. The hopper and cutting chamber of the shredder should be so designed to accommodate the waste bag full of bio-medical waste.
4. The shredder blade should be highly resistant and should be able to shred waste sharps, syringes, scalpels, glass vials, blades, plastics, catheters, broken ampoules, intravenous sets/ bottles, blood bags, gloves, bandages etc. It should be able to handle/ shred wet waste, specially after microwave/ autoclave/hydroclave.
5. The shredder blade shall be of non-corrosive and hardened steel.
6. The shredder should be so designed and mounted so as not to generate high noise & vibration.
7. If hopper lid or door of collection box is opened, the shredder should stop automatically for safety of operator.
8. In case of shock-loading (non-shreddable material in the hopper), there should be a mechanism to automatically stop the shredder to avoid any emergency/accident.
9. In case of overload or jamming, the shredder should have mechanism of reverse motion of shaft to avoid any emergency/accident.
10.The motor shall be connected to the shredder shaft through a gear mechanism, to ensure low rpm and safety.
11.The unit shall be suitably designed for operator safety, mechanical as well as electrical.
12.The shredder should have low rotational speed (maximum 50 rpm). This will ensure better gripping and cutting of the bio-medical waste.
13.The discharge height (from discharge point to ground level) shall be sufficient (minimum 3 feet) to accommodate the containers for collection of shredded material. This would avoid spillage of shredded material.
14. The minimum capacity of the motor attached with the shredder shall be 3 kW for 50 kg/hr, 5 kW for 100 kg/hr & 7.5 kW for 200 kg/hr and shall be three phase induction motor. This will ensure efficient cutting of the bio-medical wastes as prescribed in the Bio-medical Waste (Management & Handling) Rules.

• Sharp pit/ Encapsulation:
A sharp pit or a facility for sharp encapsulation shall be provided for treated sharps. An option may also be worked out for recovery of metal from sharps in a factory.

• Vehicle/Container Washing Facility:
Every time a vehicle is unloaded, the vehicle and empty waste containers shall be washed properly and disinfected. It can be carried out in an open area but on an impermeable surface and liquid effluent so generated shall be collected and treated in an effluent treatment plant. The impermeable area shall be of appropriate size so as to avoid spillage of liquid during washing.

• Effluent Treatment Plant:
A suitable Effluent Treatment Plant shall be installed to ensure that liquid effluent generated during the process of washing containers, vehicles, floors etc. is disposed after treatment. The treated effluent shall comply with the stipulated regulatory requirements.

All the treatment equipment installed at the CBWTF shall comply with the standards stipulated in the Bio-medical Waste (Management & Handling) Rules, 1998.

F. INFRASTRUCTURE SET UP :

The CBWTF shall have enough space within it to install required treatment equipment, incoming and out going waste storage area, vehicle-parking and washing area, Effluent Treatment Plant (ETP), staff room etc. The required area for CBWTF would depend upon the projected amount of bio-medical waste to be handled by it. A CBWTF shall have the following infrastructure:

H. COLLECTION AND TRANSPORTATION OF BIO-MEDICAL WASTES

The collection and transportation of bio-medical waste shall be carried out in a manner so as to avoid any possible hazard to human health and environment. Collection and transportation are the two operations where the chances of segregated bio-medical waste coming in contact with the public, rag pickers, animals/birds, etc are high. Therefore, all care shall be taken to ensure that the segregated bio-medical waste, handed over by the healthcare units, reach CBWTF without any damage, spillage or unauthorized access by public, animals etc.
A responsible person from the CBWTF operator shall always accompany the vehicle to supervise the collection and transportation of bio-medical waste.

H.1 Collection of bio-medical waste:

Generator of the bio-medical waste is responsible for providing segregated waste to the CBWTF operator. The wastes shall be segregated as per the provisions of the Bio-medical Waste (Management & Handling) Rules, 1988. The CBWTF operator shall not accept the non-segregated waste and such incident shall be reported to the Prescribed Authority. Temporary storage at healthcare unit shall be designated
The coloured bags handed over by the healthcare units shall be collected in similar coloured containers with cover. Each bag shall be labeled as per the Schedule III & IV of the Bio-medical Waste (Management & Handling) Rules, so that at any time, the healthcare units can be traced back that are not segregating the bio-medical wastes as per the Rules. The coloured containers should be strong enough to withstand any possible damage that may occur during loading, transportation or unloading of such containers. These containers shall also be labeled as per the Schedule III of the Rules. Sharps shall be collected in puncture resistant container.
The person responsible for collection of bio-medical wastes shall also carry a register with him to maintain the records such as name of the healthcare unit, the type and quantity of waste received, signature of the authorised person from the healthcare unit side, day and time of collection etc.

H.2 Transportation of the collected bio-medical waste to the CBWTF:

The bio-medical waste collected in coloured containers shall be transported to the CBWTF in a fully covered vehicle. Such vehicle shall be dedicated for transportation of bio-medical waste only. Depending upon the volume of the wastes to be transported, the vehicle may be a three-wheeler, light motor vehicle or heavy duty vehicle. In either case, the vehicle must posses the following:

(i) Separate cabins shall be provided for driver/staff and the bio-medical waste containers.
(ii) The base of the waste cabin shall be leak proof to avoid pilferage of liquid during transportation.
(iii) The waste cabin may be designed for storing waste containers in tiers.
(iv) The waste cabin shall be so designed that it is easy to wash and disinfect.

Depending upon the area to be covered under the CBWTF, the route of transportation shall be worked out. The transportation routes of the vehicle shall be designed for optimum travel distance and to cover maximum number of healthcare units. As far as possible, the transportation shall be carried out during non-peak traffic hours. If the area to be covered is very large, a satellite station may be established to store the bio-medical waste collected from the adjoining areas. The wastes so stored at satellite station may then be transported to the CBWTF in a big vehicle. It shall be ensured that the total time taken from generation of bio-medical waste to its treatment, which also includes collection and transportation time, shall not exceed 48 hours.

I. DISPOSAL OF TREATED BIO-MEDICAL WASTE

The treated bio-medical waste shall be disposed as per the following table:

Cost to be charged from the healthcare units plays an important role in sustaining the project. The cost shall be so worked out that neither it becomes a monopoly of the CBWTF operator nor the interest of the CBWTF operator is overlooked. Accordingly, it is recommended that cost to be charged from the healthcare units shall be worked out in consultation with the State Pollution Control Board/Pollution Control Committee and the local Medical Association.

K. SETTING UP AND OPERATION OF CBWTF
