This document discusses biomaterial waste disposal. It defines biomaterials and biomedical waste. Biomedical waste is generated from healthcare facilities like hospitals, dental clinics, and laboratories. The waste is categorized according to WHO standards and includes infectious, hazardous, and general waste. Proper disposal methods are important to avoid health and safety issues. Waste should be segregated, treated on-site if possible, packaged, transported, and disposed of according to principles of waste management and local regulations to protect workers and the environment. Common treatment methods for biomedical waste include autoclaving, incineration, chemical disinfection, and microwaving to eliminate harmful microorganisms.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

4. INTRODUCTION
• A biomaterial is any matter,surface or construct that interacts
with the biological systems,Such substances can range from
an inert implant to biologically integrated grafts.
• The fist historical use of biomaterials dates to antiquity,when
ancient Egyptians used sutures made from animal sinew
• Biomaterials are materials which are used in medicine and
dentistry to come in contact with living tissues.
• The familiar tooth filling is where most humans first
encounter the biomaterials but increasingly many people rely
on more crirtical implants such as joint replacements,
particularly hips and cardiovascular repairs.
5. • A designed biomaterial should serve its purpose in the
environmentof the living body without affecting the other
bodily organs.
• These biomaterials have embraced biology as basic science
on which they build
• Metal ceramics,plastic,glass and even living cells and tissue
all can be used in creating biomaterials.
• They can be engineered into molded or machined parts
,coatings,fibres,films,moans and fabrics for use in biomedical
products and devices.
• These may include heart and valves ,hipjoint
replacements,dental implants or contact lenses.
6.
7. DEFINITIONS
• Biomaterial:A natural or synthetic material(as a polymer or
metal) that is suitable for introduction into living tissue
especially as a part of a medical device(as an artificial heart
valve or joint or implant)
[Medical definition]
Waste Management:It includes the activities and actions
required to manage waste from its inception to its final
disposal.
Biomedical waste:Biomedical waste is any waste that is
generated as a by-product of healthcare work at doctor’s
surgeries, dentists, hospitals and laboratories. It includes any
material that could come into contact with the body during
diagnosis, research, drug administration or any type of
treatment.
8. Sources of biomaterial waste
• Hospitals,Dental clinics
• Laborateries and research centre
• Mortuary and autopsy centre
• Blood banks
• Nursing homes for the elderly
• Animal research and testing labs
16. Hazards of biomaterial waste
• Health-care waste contains potentially harmful
microorganisms that can infect hospital patients, health
workers and the general public. Other potential hazards may
include drug-resistant microorganisms which spread from
health facilities into the environment.
• Adverse health outcomes associated with health care waste
and by-products also include:
• Sharps-inflicted injuries;
• Toxic exposure to pharmaceutical products, in particular,
antibiotics and cytotoxic drugs released into the surrounding
environment, and to substances such as mercury or dioxins,
during the handling or incineration of health care wastes;
17. • Chemical burns arising in the context of disinfection,
sterilization or waste treatment activities;
• Air pollution arising as a result of the release of particulate
matter during medical waste incineration;
• Thermal injuries occurring in conjunction with open burning
and the operation of medical waste incinerators; and
• Radiation burns
20. Principles of Biomaterial Waste Management
• General principles of hygiene and sanitation:Observance of
general principles of hygiene and sanitation such as cleanliness,
good house keeping, adequate supply of safe water, sanitary
facilities and proper ventilation are essential components of a
good bio-medical waste management plan.
• Waste minimization: It is essential that every waste generated
from the hospital should be identified and quantified. Hospitals
should endeavour to reduce waste by controlling inventory,
wastage of consumable items and breakages etc. Waste can also
be minimized by recycling certain waste such as glassware,
plastic material etc after proper cleaning and disinfection.
• Waste segregation: Segregation of waste at source and safe
storage is the key to whole hospital waste management process.
Segregation of various types of wastes into different categories
according to their treatment/disposal options should be done at
the point of generation in colour coded plastic bags/containers as
per schedule II of the gazette notification. The needles and
syringes should be disinfected and mutilated before segregation.
21. • Waste treatment on site: Microbiological and
biotechnology waste being highly infectious should be
treated on site by autoclaving/microwaving/chemical
treatment.
• Waste transportation: The waste should be transported to
kerb collection area in covered container.
• All containers should have biohazard label according to
schedule III of the gazette notification.
• If a container is transported from the premises where
biomedical waste is generated to any waste treatment facility
outside the premises, the container shall, apart from the label
prescribed in schedule III also carry information prescribed
in schedule IV.
• The containers and the vehicles used for transportation of
biomedical waste should not be used for any other purpose.
• Care should be taken to avoid spills.
22. Types of biomaterial waste disposal
• 1.Autoclaving
• The process of autoclaving involves steam sterilization.
Instead of incineration, which can be expensive, autoclaving
simply introduces very hot steam for a determined amount of
time. At the end of the process, microorganisms have been
completely destroyed. This process is particularly effective
because it costs much less than other methods, and doesn’t
present any personal health risks. While some biomedical
waste isn’t able to be disposed of via autoclaving,
around 90% of materials are sanitized this way before being
sent on to a landfill.
• 2. Incineration
• The major benefits of incineration are that it is quick, easy,
and simple. It effectively removes the waste entirely, and
safely removes any microorganisms. However, when burning
hazardous materials, emissions can be particularly dangerous.
Some states prefer for waste disposal companies to look
towards incineration as their first choice, but materials must
be reviewed and determined as safe to burn.
23. • 3. Chemicals
• When it comes to liquid waste, a common biomedical waste
disposal method can be chemical disinfection. Chlorine is a
regular choice for this process, and is introduced to the liquid
waste in order to kill microorganisms and pathogens.
Chemical disposal can also be used for solid wastes, but it is
recommended that they be grinded first to ensure maximum
decontamination. Liquid waste, once decontaminated, is then
disposed into the sewer system.
• 4. Microwaving
• During this process, waste is shredded, mixed with water,
and then internally heated to kill microorganisms and other
harmful elements. One of the main benefits of this process is
the shredding aspect; it lowers the volume of biomedical
waste, and it is reportedly more energy efficient to use this
method than to incinerate. While it can’t be used for all
biomedical wastes, it can be utilized for a good 90% of it,
just like autoclaving.
33. The wastes generated in Dentistry is broadly
classified as:
• Mercury containing wastes
• Silver containing wastes
• Lead containing wastes
• Impression material wastes
• Titanium based wastes
• Metal based wastes
• Sharps
• Zinc based wastes
• Gypsum based wastes
• Resin based wastes
35. WASTES MANAGEMENT
Mercury containing wastes SCRAP AMALGAM:
Premeasured amalgam capsules
Scrap amalgam containers
Amalgam separators
Disposable suction traps
ELEMENTAL MERCURY:
Mercury spill kit
Silver containing wastes Silver recovery/separator unit
Lead containing wastes Lead aprons
Lead foils
36. Metal based waste Base metals of crown and bridge ,CPD and
prefabricated crowns-after disinfection
given back to dental lab for
recasting(recycling)as properties like
hardness etc are not affected when mixed
and used with fresh alloy.
Impression trays(metal)-disinfected and
handed over CWC separately for
recycling,disposable impression
trays(thermoplastic resin with reinforced
fibres)are used
Titanium based waste Dental implants-scrap titanium
Impression materials(used in making dental
impressions)
Rubber based impressions-Sanitary landfill
Impression compound-solid waste after
disinfection
Alginate(left over part after mixing)-to generate
calcium silicate cement through high
temperature calcinations,o it can be segregated
37. Sharps Puncture proof container
Zinc based wastes Disposed as soiled wastes and handed over to
CWC for proper management
Gypsum based wastes Dental casts-regular non-hazards waste and
finally disposed as landfill. Can be disposed
into white lided container.
A study reveals that when 1 ton of ordinary
gypsum is recycled it saves around1000
pounds of black alkali,1 ton of lactic
acid,500kwh of energy.
38. Resin based wastes RPD-Metal part- removed manually and
kept with metal based waste container
Acrylic part-resin based waste container and
should be handed over to CWC fpr proper
management
Ceramic waste Not hazardous to environment but ofcourse it
will utilize the landfill so instead of just
discarding it as regular waste it should be
segregated for recycling
Liquid waste/chemical
wastes/disinfectants/sterilizing agents
Infected body fluid-collected into 10%sodium
hypochlorite solution for 20min & then drained
into sewage.
Chemical waste-first neutralized &drained into
sewage
Disinfectants&sterilizing agents-first
neutralized and then poued into septic system.
39. Expire or outdated medications Handed over to supplier and incinerate at
higher temperature
Non-hazardous waste Re-usable devices for dental procedures are
recommended.
Plastic waste Should not be burned in open or closed
chamber as it produces dioxin and furans
which is bio-accumulative as well as
carcinogenic.
Infected plastic waste-shoul be
autoclaved,shred and given to local vendor for
recycling.
Non-infected plastic-handed over to
40. THE SAFE DISPOSAL OF DENTAL WASTE
• The first and foremost thing a practicing dentist should do is
to dispose of waste materials far from the dental set up to
prevent any contamination.
• This waste can be anything like plastic gloves, water cups,
used napkins, suction tips, etc.
•
After every dental treatment, have a dental assistant properly
clean and disinfect the area.
• This is as important as cleaning the unit because it is very
likely that waste materials will be found thrown on the floor,
which is often overlooked and ignored.
• Using a disinfectant is the right way to make sure no cross-
contamination occurs.
41. • A trash can is surely present in every dental setup, but not all
kinds of waste can be thrown in it directly.
• For example, blood-soaked cotton, suction tips, extracted
teeth, used needles, amalgam fillings containing mercury, etc.
are all hazardous things that need proper waste management
in dentistry.
• Dentists must make sure to use biomedical containers,
double bags, puncture-resistant boxes, and proper recycling
services when it applies.
42. • The ultimate guide to the disposal of waste within the dental
surgery
• CATEGORIES OF WASTE AND THEIR METHOD OF
DIPOSAL
• Hazardous and Non-hazardous wastes must be appropriately
segregated.
• Non-Hazardous waste disposal:
• Firstly,Non-hazardous wastes include offensive waste,non-
cytotoxic,,domestic waste,office waste,x-ray film, and lead fil
and dental plaster casts all of which are disposed in different
ways.
43. • Secondly hazardous wastes which may be infectious include
clinical (soft) waste,sharp waste,sharp waste uncontaminated
withm medicines and sharps waste contaminated with cytotoxic
medicines.
• 1)Soft clinical waste:Orange sacks
• 2)Sharps:Yellow lided rigid containers
• 3)Sharp waste uncontaminated with medicines:Yellow rigid
container with an orange lid.
44.
45. Prosthetic waste management in HIV patients
Sharp items such as needles.scalpel blades Should be placed in puncture resistant
containers marked with biohazard label
Gloves,masks,wipes, paper drapes,surface
covers that are contaminated with body fluids.
Handled with gloved hands and discarded in
sturdy,impervious plastic bags to minimize
human contact.
Blood,disinfectants,sterilants Should be carefully poured into a drain
connected to a sanitary sewer system..
Disposable materials Management

Editor's Notes
These biomaterials come from either nature or synthesized in the lab using a variety of chemical approaches.Biomaterials are used for the reparation or reconstruction of Musculo-skeletal system and soft tissue regeneration as wella s in various medical instruments and devices.
Waste can be solid,liquid or gas.waste management can be biological,industrial,household.
Acc to who high income countries give 0.5 kg of hazardous waste per hospital bed per daywhile low income countries give 0.2kg
The infectious agents enter the body through puncture,abrasion.cut in the skin,by inhalation etc
The main reason why properly disposing of the waste generated from dental interventions is important is because many diseases can be transmitted by contact with these materials. For example, it is known that the improper disposal of needles can cause accidental punctures to garbage collectors, which can lead to serious health issues for them. But it is also important to manage the waste inside the dental office to prevent cross-contamination from one patient to the next.
Another important reason is the environmental impact of this waste. Contaminant materials like mercury, lead, and some liquids used in dental procedures can be very harmful to the environment, so preventive measures are vital.
Non-infective wastes-black bags.PPE kits should be disposed in yellow bins
