List of waste types Jump to . Waste comes in many different forms and may be categorized in a variety of ways. The types listed here are not necessarily exclusive and there may be considerable overlap so that one waste entity may fall into one to many types.

List of waste typesWikipedia

The different sources of wastes can be identified by recognizing the types of wastes. Let us first define the term waste. Waste is any substance which is discarded after primary use or in other words, there is no further use for the product. We generate a huge amount of wastes in our day to day life.

Different Types and Sources of WastesBiology

Recycling is the process of making used or unwanted products into new remanufactured products. In other words, recycling is the art of making waste into a resource! There are different processes for recycling different items: Paper. The paper is taken to a recycling plant where it is separated into different types and grades.

The Recycling Process

Printed Circuit Board Recycling Methods 1. Introduction to Printed Circuit Boards The Printed Circuit Board (PCB1) manufacturing process is very complicated, involving many special chemicals and valuable materials. These materials discharge into the environment in the forms of wastewater, spent solution and solid waste.

 · What types of electronic wastes are recycled? What usable items do they become? . in printed circuit boards). The wide variety of e-waste makes it hard to generalise the material content – for example, fridges and air conditioners in particular contain refrigerants to enable cooling to take place, but these refrigerants may also contribute .

What types of electronic wastes are recycled? What usable

Types of waste Generally, waste could be liquid or solid waste. Both of them could be hazardous. Liquid and solid waste types can also be grouped into organic, re-usable and recyclable waste. Let us see some details below: Liquid type: Waste can come in non-solid form. Some solid waste can also be converted to a liquid waste form for disposal.

A6: Yes, once you have classified the circuit boards generated onsite as exempt scrap metal. The final e-waste regulations (effective February 4, 2009) allow greater flexibility in treatment of circuit boards. This flexibility has been accomplished by viewing the recycler as a “generator” of the circuit board.
