Waste hierarchy

The main driving force towards recycling has been national and international plastic waste management policy. Within the EU, the policy is based on waste hierarchy, meaning that the first choice is waste prevention and then waste recovery (reuse, recycling and energy recovery), with preference to material recovery. Thus the type of legislation found is ... 

North Carolina Sets Waste Minimization as Top Priority for Hazardous Wastes - Hierarchy... 

Dealing with waste is one of the important hot-button societal issues of any country, where waste prevention including the capability of reusability has highest priority in the waste hierarchy defined by the waste framework directive (European Union, 2008). Reuse option stands as the second highest priority, next to waste prevention in the order of hierarchy. When we talk about reuse, at times the material under question might need preparation for being reused, which is also included in the reuse option that is discussed here. 

It allows specific waste streams to depart from the waste hierarchy... 

Waste Hierarchy Refers to the three caveats of the green movement, reduce, reuse, recycle, which classify waste-management strategies according to their desirability. 

The practical possibilities of reuse (which is a highly rated solution in the waste hierarchy) are very limited at the present time. This is because FRP materials are often made to order and are thus usually designed for a particular application, so they do not conform to standardised shapes or material properties. The reuse of FRP pultruded members, in particular, seems quite unlikely owing to the difficulties of recalculating the residual mechanical properties and of reliably assessing material degradation or creep effects (Conroy et ah, 2006). 

The waste hierarchy refers to the 3Rs of reduce, reuse and recycle, which classify waste management strategies according to their desirability. The 3Rs meant to be a hierarchy, in order of importance. However in Europe, the waste hierarehy has 5 steps reduce, reuse, recycle, recovery and disposal. 

The waste hierarchy has taken many forms over the past decade, but the basie eoneept has remained the cornerstone of most waste minimization strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste. 

This assessment should identify all the waste streams from all stages of the process. Such work should include all minor releases from storage tank vents, effluent pit emissions, etc. For each waste stream consideration should be given to the waste hierarchy of reduction, reuse, recycle as well as end of pipe treatment and disposal. 

What is waste to one company could be a raw material to another. Companies who need to apply for Pollution Prevention and Control (PPC) Authorisation will need to demonstrate what action has been taken to minimise waste on their sites. They need to manage their waste without endangering human health or the environment and should follow the Waste Hierarchy ... 

The waste hierarchy established by the European Commission in 1989 [20] laid down a priority order in waste management options ... 

The basic principle is to prioritize different waste management options according to their environmental desirability. The top of food waste hierarchy is the prevention of food waste and recovery of food to feed hungry people. In this case, some issues, including society, ethics, and sanitary conditions, require the food must be edible. 

The main problem is that a large fraction of wasted food is perishable and not always edible. This makes collection, processing, and transportation for human consumption very difficult. In fact, Waste prevention at the top of the waste hierarchy is really a catchphrase without much content, the use-and-throw society is a reality with its huge turnover, creating the ever increasing mountains of waste" (Tjell, 2005).

Reuse and recycling of materials is an integral part of the waste hierarchy which is fully endorsed and positively promoted by the Agency. 

According to the waste hierarchy developed by the European Union Directive 2008/98/EC (European Union, 2008), the effort priorities for dealing with spent material are expressed as "Re-duce, Re-use, Re-cycle". This means that only minimum amounts of substances should be used in a process. If possible, the substance should then be reused and reincorporated into the system and eventually recovered from the waste stream. Different operations are required in order to comply with the regulations.
