Refresher training course & training status on reports

The refresher course is for classifiers who have completed our advanced waste classification course but more than 3 years ago. The refresher course will update your knowledge about relevant changes to waste classification including the law, legislation and guidance plus new features in the software that improve productivity and accuracy. It will also review some of the common mistakes that classifiers make including how to spot them when reviewing someone else’s classification report.

In line with the refresher training, we have made initial steps towards achieving a ‘competent person status‘ by adding a classifier’s training record to their classification reports. Since the start of February, reports now document the dates when a user has attended one or both days of our two day course.

Following the refresher courses in Warrington (March 12th), Dublin (7th April) and Reading (2nd June), the reports will also document classifiers completion of the triennial refresher course.

These course(s) are now available for booking, please do so through our online booking form

Refresher course outline

  • Brief overview of legislative changes and new guidance (e.g. packaging, soil sampling) introduced over the previous three years.
  • General review of the results of the on-line assessment, examples of common mistakes.
  • Mini workshops where we look at real examples of data from a number of different waste streams
  • Review of new functionality added to HazWasteOnline such as processing WAC data, PAH double ratio plots, averaging replicate sample data.


  • Workshop – multi-part exercise where delegates are given the details of a waste stream and have to work out whether it’s hazardous or not – includes desktop study, selection of EWC code analysis of a “poor” classification, defining a lab test suite, assessing sampling requirements, import and processing composite/replicate lab data using the .hwol file, identification of metal species, adding missing non CLP substances, identifying the types of the hydrocarbons and of course data processing a number of composite samples.

New YouTube videos

At the time of last months newsletter we had released 3 new YouTube videos, these being tutorials on:

  • Manual data entry
  • Creating a waste stream template
  • Importing your data using a HazWasteOnline file (.hwol file)

Since then we have released even more, including:

  • Importing your data using Excel
  • Creating your own substance/determinand 
  • Using .hwol files to add a data set to an existing job 
  • Dealing with ‘potentially hazardous’ hazard statements 

Please follow the following link to our YouTube channel to view them.

Please subscribe as more videos will follow shortly.

Labs that can publish .hwol files

  The current list of labs that support the .hwol data file format is:

  • ALS (Deeside)
  • Chemtest (Newmarket)
  • DETS (South)
  • Element (Exova Jones)  (Deeside)
  • i2 Analytical

If your wish to start importing .hwol data files from one of these labs:

  • simply ask the lab for the .hwol file along with your normal deliverables
  • watch our YouTube tutorial on how to set up your account and process .hwol files, and/or
  • contact Support (support@onetouchdata.com) and we will guide you through the process over the phone

Status of labs working on the production of the .hwol file

  • DETS North (Co, Durham) 
  • Chemtech (Co Durham) – Beta testing stage
  • ELAB (Kent) 
  • Socotec (Burton upon Trent)
  • Envirolab (Hyde)

UK – New Waste Crime Task force

Launched on 16th January 2020, the Joint Unit for Waste Crime (JUWC) brings together law enforcement agencies, environmental regulators, HMRC and the National Crime Agency for the first time.  The new task force, led by the Environment Agency, will be dedicated to tackling serious and organised waste crime, including dumping hazardous materials on private land and falsely labeling waste so it can be exported to unsuspecting countries.More information can be found here:
