Explanation

If the planning and mitigation measures fail and redundant or obsolete stock is identified, it needs to be removed from the current inventory location as quickly as possible. There are some methods to dealwith these types of stock. The worst case scenario is disposal to landfill, which is inadvisable if it can be avoided, both from environment point of view and the financial costs of such disposal.

For example, the problem of obsolete pesticides remains extremely serious and urgent. Many of the stocks identified continue to deteriorate thereby giving rise to an ever escalating source of severe pollution and posing a threat to human health, the environment and development in particular. To reduce the impact of obsolete pesticides on environment, FAO initiated a project in Yemen in which a total of 262 tonnes of obsolete pesticides were removed from 20 different sites and successfully disposed of between March and June 1996. The major field operation was completed in six weeks during which period almost all obsolete pesticides were brought to a central location and subsequently shipped to the United Kingdom for incineration.

Explanation

There are two main processes of recycling – open loop recycling and closed loop recycling.

Open Loop Recycling

Open loop recycling is a method that delays disposal by converting manufactured goods and spent materials into both new raw materials, which can be used for a manufacturing purpose, as a fuel source for a different manufacturing process and waste products.

Typically, materials recycled through open-loop recycling will be used for purposes different from their original purpose.

This means that the input into the recycling process is converted to a new raw material, which can be used as an input into another manufacturing process.

Materials in an open loop recycling process are treated using various forms of treatment including heat, chemical reactions, or physical crushing.

Closed Loop Recycling

Closed loop recycling is a process where waste is collected, recycled and then used again to make the same product it came from. This process is restorative and regenerative by design and aims to keep materials at their highest utility and value always.

Closed loop recycling is focused on resource sustainability, which means that recycling of a material can be done indefinitely without degradation of properties. In this case, conversion of the used product back to raw material allows repeated making of the same product, which helps hazardous waste generators reduce carbon footprint and achieve corporate sustainability initiatives.

Closed-loop recycling is common in specialized industries, such as the computer and battery industries, which use expensive or complex goods that cannot easily be broken down post-consumption into constituent materials.

A prime example of a closed-loop recycling process is the recycling of aluminum cans. Aluminum can be recycled to form new cans with little material degradation or waste creation.
