WASTE CLASSIFICATION

Waste Classification at our NATA Accredited laboratory can be performed on liquid waste, solid waste and organic waste materials. We service private, commercial, industrial and civil sectors.

Chemical and hazardous waste analysis of liquid or solid materials can be crucial to the reuse or disposal of a material and provide economic and strategic benefits to the outcome of any project. We classify waste in accordance with industry compliant regulatory instruments.

SOIL TESTING

SESLs NATA Accredited Laboratory (#15633) hosts a variety of soil analyses for a wide range of environmental, agricultural and urban horticultural sectors.

SESL can test to meet Australian Standards for soils and organic products (AS4419, AS3743, AS4454), NSW Roads and Maritime Services (RMS) Specifications, Queensland Transport and Main Roads Specifications (MRTS 16), resource recovery order requirements (NSW Biosolids, etc.) and the majority of Client-provided specifications. Our analysis suites also cover landscape specifications that SESL has developed and published in ‘Soils for Landscape Development, Selection, Specification and Development (Leake and Haege 2014)’ to ensure that your soil meets the required end use.


We test passive amenity turf, sports fields (USGA), bunker sands, cricket wickets, mass planting, garden beds, street trees, on slab podiums, green walls, green roofs, raingardens, stormwater filtration systems, wetlands and display beds.

PLANT TISSUE

Plant tissue analysis allows you to determine the nutrients for optimal crop production and quality. It also allows for an in-depth understanding of the interaction between the soil media and the plant nutrient uptake.


Plant performance or failure can be the result of a range of factors, including poor nutrients, unsatisfactory conditions (climate, competition or soil), poisoning or surrounding hazardous material. SESL’s laboratory is equipped with the knowledge and experience to get to the root of your plant’s issues.

COMPOST TESTING

Compost testing, mulch testing and soil conditioner testing are backed by our specialist horticultural and environmental consulting teams. We provide the full range of AS 4454-2012 testing methods which are classified by maturity (Raw Mulch, Pasteurised Product, Composted product, Mature Product) and particle size (Soil Conditioner, Coarse Mulch and Fine Mulch). The testing assesses the compost performance, chemical and physical characteristics to satisfy national compliance declarations and abide by Australian standards and regulations in the industry.


Our results can be presented against the AS4454 specification criteria for easy comparison of the analysis results and target ranges within the Standard.

 

  • Compost testing of physical parameters

  • Carbon, Nitrogen, Ammonium

  • AS 4454 Compost Wettability testing

  • AS 4454 Composts, Soil Conditioners and Mulches

  • Compost nutrient testing
