decide if a material is waste or not: general guide

If you are the producer or holder of a material and you’re unsure whether it’s a waste or not, you can use this guidance to assess the status of your material. A material can include any substance or object

You must try to prevent and minimise the production of waste as much as possible. See the waste hierarchy guidance which explains the different options you have for managing waste. It also shows which options are the best to prevent harm to the environment

When assessing whether a material is waste or not, discarding doesn’t simply mean throwing away or getting rid of something. Discarding also covers activities and operations such as recycling and recovery operations, which put waste material back to good use

decide if a material is waste or not: general guide

When a householder takes items to a household waste recycling centre and puts them into the general waste skip, all the items will be considered waste. Even if any of the items were suitable for reuse before they were put into the general waste skip they are still waste. By putting the items into the skip the householder’s intention was to discard the items and not for them to be reused

When a business receives waste which it intends to process so it can be used again it is still waste, even if it has a positive economic value. For example when a scrap metal merchant takes waste scrap metal to a business who can convert it to a steel product – the scrap metal is waste because the producer or holder who gave it to the scrap metal merchant discarded it

When a construction company excavates land for development and realises that some of the extracted soil may be suitable for reuse at a site other than where it was produced, that soil is likely to be waste. The soil is a residue of the construction development. It is waste unless it can meet the by-product test. It may also be used as a non-waste if it is used on the same site or at another site with or without further processing – see all the requirements in the CL:AIRE code of practice

decide if a material is waste or not: general guide

Recovery is any operation which has the main result of waste serving a useful purpose, by replacing non-waste materials that would otherwise have been used to fulfil a particular function, for example turning food waste into compost. Find more examples in annex II to the Waste Framework Directive – as amended

Preparation for reuse is the operation or process of checking, cleaning or repairing materials that have been discarded and are waste so that they can be used again for their original purpose as a non-waste without any other pre-processing. Preparation for reuse might include the repair of bicycles, furniture or electrical and electronic equipment

Recycling is any operation by which waste is reprocessed into products, materials or substances, for either its original or other purposes. For example, crushed waste glass graded for blasting or playground surfaces from waste tyres. Recycling includes the reprocessing of organic material

decide if a material is waste or not: general guide

For example, when manure or slurry is used to spread to land as fertiliser it isn’t classified as waste as long as it’s used as part of a lawful operation – for example it complies with the Nitrates Directive and takes place on clearly identified parcels of land without prior processing. The reason for this is that animal faeces are a by-product of keeping animals and make up a traditional fertiliser where other fertilisers may be regarded as a substitute

However, where manure or slurry is spread in such a way that it exceeds crop requirements, is of no benefit to the land or provides no ecological improvement, then it’ll be waste and spreading it to land simply to get rid of it is classified as a disposal operation

If you don’t follow the rules that apply to your waste the environmental regulator may take enforcement action against you. Read this information to find out how the regulator decides whether or not to take enforcement action:

decide if a material is waste or not: general guide

For example, a simple check could be to identify that no processing is required before the material can be used again for its original purpose. Extensive processing could be when the material undergoes several recovery operations before it becomes a new product

There are specific tests that must be met to make sure that a waste has achieved end of waste. See the detail on EU end of waste regulations, quality protocols and the end of waste test in the turn your waste into a new non-waste product or material guidance

You can use the IsItWaste online tool to do a self assessment and help you decide if your production residue is a by-product or waste. If you are unsure, you can contact your environmental regulator to ask their opinion

decide if a material is waste or not: general guide

If your material meets all of the conditions and is a non-waste by-product it must then meet other relevant product legislation requirements, for example the registration, evaluation, Authorisation and restriction of chemicals (REACH) Regulation

The environmental regulator’s opinion on whether a material is waste or not is based on relevant legislation and case law. If you disagree with the opinion of your environmental regulator, it’s ultimately the court that interprets the law to make the final decision. See previous examples of EU court judgments in the legal definition of waste full document

For its extensive practical experience, 911 Metallurgist has a clear understanding of what successful mineral processing engineering is and how to go about achieving it. Your goal is the production of a material that is marketable and returns you and your investors sustainable revenues

Although improvements to the metallurgical processes have been made over the years the fact is that the unit operations, the machines, those too often called “black boxes” involved have not evolved or changed much since inception. Ore is reduced in size, chemicals are added and minerals separated and upgraded to produce a marketable product.  Much of this process is mechanical and generally mistaken for some dark alchemy. We are the Anti-Alchemists

metallurgist & mineral processing engineer

Our vast experience has been gained through operation and start-up of both small and large scale mining/metallurgical operations in a range of commodities in the base metals (Cu, Pb, Zn) and the precious metals (Au, Ag,)

A solid metallurgist understands, the most important aspect of an operating process is its stability. Simple to say, but generally the most ignored in mineral processing. Linked unit operations require each to be stable, and each contains a different set of variables that have to be contended with.  Thanks to some degree of stability: operating changes can be made and evaluated; increases in throughput can be made; and equipment performance improved. The more complicated the processes become, the more difficult it is to achieve and maintain stability.  In mineral processing, unlike most processing operations, we have limited control of the main input, the feed ore. In most cases this inherently is variable and usually outside of the processors control

Because you are too close to your own story, you might not see the forest for the trees and have chaos mistaken for stability.  We, you, and your group have been battling plant problems for weeks, you start to accept chaos as a daily state of affair and consider it your new stability

metallurgist & mineral processing engineer

Each mineral processing plant is different: with varied ore types, mining equipment, and management (operating) philosophy. The evaluation and prioritisation of variables that affect the plant performance is the primary function. Implementing changes within the constraints imposed can be difficult, as resources may be limited

Invariably the ability to solve problems can be confusing due the large numbers of variables that may impact the processes. In most cases problems are not metallurgical in nature but rather operational and mechanical. Problem solving is a process and in many operations this ability is absent. All too often many changes are made together without a solution resulting, on more confusion. Most plants learn to live or survive their problems, not to solve them

Our engineering team has a global experience in the mining industry across all facets of the mine life-cycle.  Our focus is to add value to your project and company by understanding your needs, employing innovative ideas and applying sound engineering while maintaining an economically driven approach. We have a combination of senior level professionals, experienced project managers, and technical staff to execute projects efficiently. We work in a partnership with our clients to achieve their company goals and operational milestones in a timely and cost effective manner
