Managing waste effectively is important in maintaining a sustainable and eco-friendly environment. To address this, it’s essential to categorize it according to its characteristics and disposal methods. Let’s explore the examples of dry and wet waste along with methods to manage them.
Dry Waste and Wet Waste Examples
Before diving into the examples, let’s find out what is dry and wet waste.
Wet wastes are moist materials, organic waste, or biodegradable waste. These include materials that can be composted and are easily decomposable by natural processes.
Dry waste refers to non-biodegradable waste materials that do not decompose easily but can be recycled and properly disposed of.
Wet Waste Examples
| Types | Sources | Examples |
| Food Waste | Residential areas, Restaurants and Religious places | Leftover food; Fruits & veg peels; Nuts and cheese; Used tea bags & coffee powder; Spoiled spices; Meat, fish & chicken remains |
| Vegetable Waste | Local street vendors and Wholesale markets | Rotten vegetable & fruits; Agri waste; Residue from farms; Weeds; Non-harvested wastage |
| Animal Waste | Slaughter Houses; Fish markets | Flesh and leftovers; Parts like scales, fish tail; Discarded residue; Small vendors/butchers |

Dry Waste Example
| Types | Sources | Examples |
| Recyclables to a new form | Residences and offices using these: Plastic, Paper, Cardboard, Glass and Metal | Glass bottles & storage jars; Packing materials; PVC pipes; Newspapers & cardboard boxes; Aluminum & steel cans; Bubble wraps; Metal packaging |
| Reusables | Residences and Commercial places | Old clothes, bags, & toys; Used Utensils; Furniture |
| Recycled and segregated for further use | Residences and offices that produce e-waste | Tiny metal pieces; Wood debris & saw dust; Ceramic pieces; Glass shards; Hard plastic films; Synthetic textiles; Tire remains; Rubber scraps |
| Non-perishables | Streets, Landfills, Playgrounds, and Construction areas | Tiny metal piece; Wood debris & saw dust; Ceramic pieces; Glass shards; Hard plastic films; Synthetic textiles; Tire remains; Rubber scraps |

Sanitary Waste Examples
It refers to waste generated from personal hygiene and medical-related activities. These are considered hazardous and require special handling and disposal methods. Improper handling leads to contamination of the environment.
| Sources | Example |
| Medical | • Bandages & wound dressings • Disposable syringes & medical supplies • PPE kits (personal protective equipment) • Gloves, masks & gowns • Expired pregnancy kits & medicines • Contaminated dental materials. |
| Menstrual | • Used sanitary napkins & tampons |
| Baby care | • Used diapers & wet wipes • Soiled cloths • Expired baby formulas • Old baby bottles |
| Personal care | • Cotton swabs, tissues, & facial wipes • Condoms • Adult diapers • Disposable contact lens |
Wet Waste Management
It includes handling, collection, and treatment of materials that are easily decomposable. For example, food scraps, kitchen waste, garden waste, and other organic matter.
1. Separation: Wet waste is separated from the dry one at the source of generation. Households and businesses often use separate bins or containers to segregate organic waste from others. Different colored bins have their distinct purposes. Green one is for wet waste and red one is for medical or hazardous trash.
2. Collection: It includes collecting wet waste by separating it from others. Municipalities or waste management agencies provide specific collection services or designated bins for the collection of organic trash.
3. Composting: It is an eco-friendly way to process organic and garden waste. It converts wet waste into nutrient-rich compost through different composting processes. This ensures ideal conditions for microorganisms and controlled composting, resulting in the best quality compost. Some countries have advanced waste management technologies for efficient wet waste management.

4. Anaerobic Digestion: Wet waste undergoes anaerobic digestion to produce biogas, which can be used for energy generation. It is a biological process where microorganisms break down organic materials in the absence of oxygen.
5. Vermicomposting: Earthworms are used to quicken the decomposition of organic waste, creating a nutrient-rich product known as vermicompost. It can be made on small or large scales, providing high-quality compost that serves as fertilizers for plants.
6. Biogas Production: This facility effectively converts organic waste using microbes, resulting in the production of valuable methane gas.

Dry Waste Management
Systematic handling, collection, disposal, and recycling of non-biodegradable waste materials that do not decompose easily are included in dry waste management.
1. Collection: After sorting of wet and dry waste at the root level through different bins (blue) and containers, the latter is collected.
2. Segregation: Different types of dry waste materials like glass, metal, and plastic are separated at this level to ensure proper recycling and disposal.
3. Transportation: Once collected and segregated, dry waste is transported to recycling facilities or treatment plants.
4. Recycling: It is the primary goal of dry waste management. This reduces the need for new raw materials by reusing plastics, paper, glass, and metals.
5. Energy from Waste: Through waste-to-energy technologies like pyrolysis and gasification, dry waste can be converted into a valuable resource.
6. Community Maintenance: Governments and local authorities often implement regulations and guidelines for proper dry waste management. Community programs like clean-up drives and recycling awareness campaigns create a sense of responsibility among residents.
In summary, effective waste management is essential for a healthier planet and involves addressing both wet and dry waste examples. Wet waste, such as food leftovers, can be managed through composting, while non-biodegradable dry waste, including storage jars, requires systematic collection and recycling.
