The document defines different types of solid waste and their classifications. It discusses how the Environmental Protection Agency defines solid waste and how it can be classified based on its physical properties, biodegradability, and environmental/health impacts. Specific types of waste are also outlined, including hazardous waste, biomedical waste, and other waste generated in accommodation areas, mess halls, and work decks. Proper disposal procedures are described for different waste streams. Overall, the document provides guidance on solid waste classification and handling procedures to facilitate proper management.

2.  Environmental Protection Agency (EPA)
defines solid waste as any
 - Garbage or Refuse
 - Sludge from wastewater treatment
plant.
 -Water supply treatment plant
 -Air pollution control facility
 -Other discarded materials like:
 1. Solid
 2. Liquid
 3. Semi-solid
 4. Contained gaseous materials
that result from industrial, commercial,
mining and agricultural operations,
including community activities

3.  CLASSIFICATION ACCORDING TO
PHYSICAL PROPERTIES:
 1. SOLID WASTE:
Generated in industries,
commercially and domestically
like plastics, bottles, papers etc.
 2. LIQUID WASTE:
 Like chemicals, oils etc.
3

4.  CLASSIFICATION ACCORDING TO
BIOACTIVITY PROPERTIES:
 1. BIO-DEGRADABLE:
This can be broken down to its
constituents by micro-organisms and
other living organisms regardless of
its composition e.g. food, paper etc.
 2. NON BIO-DEGRADABLE :
 These are not able to be broken
down for many years, e.g. plastics,
bottles, cans etc.

5.  CLASSIFICATION ACCORDING TO
ENVIRONMENTAL AND HEALTH IMPACT:
 1. HAZARDOUS:
These are solids, liquids or gases that are
dangerous or potentially harmful to health or
environment. They can be: Corrosive,
Ignitable(Inflammable), Reactive, or Toxic.
Or listed by EPA under F-list (Nonspecific source
waste), K-list (specific source waste)e.g.
petroleum refining etc, P-list and U-list
(Discarded commercial chemical products).
2. NON HAZARDOUS :
 These are those solid wastes that are not
listed or exhibit any of the characteristics
attributed to hazardous wastes.
5

6.  Poorly segregated and
managed waste can adversely
affect the following:
 1. Our Health
 2. Our Climate
 3. Our Socio-economic status
 4. Our Environment, especially
the marine and coastal areas.

7.  A. BIOHAZARD/MEDICAL WASTE:
 PIC: The Medic
 1. SHARPS CONTAINER:
-Needles with syringes
-Needles
-Needles with attached tubing
-Broken glass, microscope slides, pasteur or other
glass pipettes contaminated with blood and blood
products.
-Blades (Razors, Scalpels, Lancets)
 LOCATION: Clinic; E-U Deck.
 DON’T dispose sharps in accommodation bins.
 USE designated receptacles.
 JANITORS: RETURN bins to Medic when ¾ full,
NEVER thrash with regular waste.
7

8.  2. BIOHAZARD CONTAINER:
-Plastic syringes without needles
-Intravenous tubing without needles
-Any other item contaminated with blood and
blood products that DOESN’T go into a sharps
container like - Soiled dressings, gauze or cotton
wool
- Soiled bandages or band aid(plasters)
 LOCATION: Clinic.
 DON’T dispose in accommodation bins or regular
thrash bin.
 USE designated receptacles with proper red
biohazard bin lining.
 ALL: RETURN such items to the Medic for proper
disposal.
 Waste is labeled and logged, before transport to
certified vendor for proper disposal.

9.  B. OTHER TYPES OF WASTE:
 PIC: Camp Boss
 Janitors(Housekeepers)
 Deck Crew and
 All Persons On Board
 1. ACCOMODATION/OFFICES:
Ensure all waste generated are
properly disposed in the designated
receptacle, to aid proper waste
management, at all times
9

10.  2. MESS HALL/KITCHEN:
Ensure all waste are disposed in designated receptacle at
all times
