Technical Services

Interwaste not only classifies waste, but the organisation's technical teams' innovative processes set the company apart in integrated waste management - which is why Interwaste is also called upon to utilise their expertise in outside situations.

Different technical services are offered by Interwaste as part of the organisations full-service scope within the waste management space.

To this end, the company offers the following technical services:

1. Waste Classification & separation:

This is the process whereby discarded material is identified and organised, by class, to ensure the proper disposal thereof. The National Department of Environmental Affairs (DEA) has developed new Waste Classification and Management Regulations, where waste is assigned into 9 hazard classes, with further expansion on the criteria for toxic and infectious substances. Through the alignment to local and global best practice, Interwaste can assist its clients in the accurate classification of waste - based on the guiding principles - to ensure the correct disposal of waste.

2. Waste collection and compacting:

Interwaste offers the collection of waste, using specialised vehicles, as well as the compacting of waste, prior to transporting it to company Materials Recovery Facilities, for final sorting and re-processing. The use of varied size bins are deployed - dependant on the requirement.

In addition to this, Interwaste also supplies special boxes for the collection of recyclables in offices.

3. Material Recovery Facilities (MRF):

Interwaste offer custom designed MRF's - which are currently in operation at a number of larger waste disposal facilities managed by them. Paper, cardboard, plastic, glass and metals collected in this manner greatly reduce the waste volume that is eventually returned to the site for disposal.

Custom designed and built MRF units are available for use at clients' sites should the volumes of recyclable wastes justify the installation.

On-site Services

With the latest in equipment and facilities, as well as expert manpower, Interwaste's qualified on-site personnel ensure all waste is separated correctly, at the source of manufacture, and ensures that the reduction of costly cross-contamination of hazardous and non-hazardous waste streams is avoided, as well as enables streamlined operations for the customer.

With the latest in equipment, plant, depots and facilities, as well as expert management, and operational systems, Interwaste ensures high levels of efficiency and unsurpassed service. The provision of qualified site personnel ensures that all waste is separated correctly, prior to being recovered and/or finally disposed of.

  • Site Management and onsite personnel
  • Waste Identification and Separation
  • Waste Minimising
  • Maximising Resource Recovery
  • The Provision of Accurate Environmental Reporting (Triple Line Reporting)

One great example of such onsite service is the Eezee Bin System.

This is an easy, neat and affordable recycling solution, deployed at commercial and industrial clients, shopping centres, sports facilities, offices and housing estates. Here all recyclable materials can be deposited into a single bin, allowing for the collection of recyclables at source, previously destined for landfill. Dedicated collection vehicles are employed to regularly collect and compact waste before transporting it to a Materials Recovery Facility for sorting and final disposal.

Metals Recovery:

To maximise value from metals recycling it is necessary to categorise, separate and process the materials to the specification of the end user. This can be offered either as an on-site service or, alternatively, the activities relating to the recycling process may be done off-site - dependant on volumes and specific client requirements. In many cases it is possible, as a result of increased efficiencies, to offset the costs of recovery management and increase revenues generated from the recycling process. This can often lead to zero-cost waste management scenario or even an income positive holistic service.

To this end, Interwaste ensure the efficient collection and processing of ferrous and non-ferrous metal waste, from depots across the country. This process includes providing bins at the client's premises, upliftment of bins once full and transport to the nearest depot where they are weighed at a SABS approved weighbridge facility.
