Green waste classification
Green waste is a type of biological waste which is organic and can be composted. Generally collected from gardens and agricultural activities, made up of leaves, tree trimmings and the removal of plants. Green wastes contain a high concentrations of nitrogen. Green waste is used to increase the efficiency of many composting operations and added to the soil of other plants to increase the soils nutritional values. Here at Waste Carriers, we strive to decrease the amount of biodegradable materials that land up in landfills.
We remove and recycle:
Windbreaks, orchards, vineyards
Orchards get cleared on a rotating cycle to remove lower producing or unhealthy deciduous fruit, citrus, and nut trees, or to replace orchards with a more valuable crop. Once orchards & vineyards become old, they tend to produce less fruit, by this time to know it’s time to chop the crop. Waste carriers provides tailor made solutions to meet our client’s requirements. We offer full turnkey services.
The NEMBA Act highlights all alien invasive species in different categories which must be removed from riparian zones as well as farmlands. These trees comprise of port Jackson’s, blue gum, wattle, rooikrans etc. these alien invasive species destroy the indigenous species inhabiting the environment and impact the ecology. These aliens are removed using our excavators with the shear or tree cutter attachment, it is then stockpiled using our front-end loaders as well as our bell loggers. Once stockpiled we position our horizontal grinder strategically to achieve optimum output. Waste carriers uses the bell loggers and excavators to feed our horizontal grinders.
Chipping of green waste
Chipping is to strategise the potential of composting as a method to beneficiate organic waste, to help divert organics from landfill disposal. Composting is a proven method of organic waste minimisation, and various local and international practices have demonstrated the effectiveness of composting organic waste which in turn reduces the amount of waste requiring landfill and the generation of landfill gas.
Due to the high percentage contribution of green waste to the total general waste generated in South Africa (i.e. up to 24% by mass1), the potential for composting in South Africa is significant and thus was investigated as a diversion alternative.
Grinding and Mulching
Mulch is anything that’s used to cover the surface of the soil to prevent weed growth and retain soil moisture. Mulching continues to gain traction in the South African forestry industry as growers around the country are realising that the high cost of the operation is more than justified by the many benefits that it brings. But choosing the right equipment is key.
We at waste carriers process green waste such as branches, brush orchards vineyards , alien invasive trees & various wood wastes.
Types of materials produced
Mulch: mulch has various benefits to farmlands. Once processed mulch can be applied to orchards & vineyards to retain moisture and save on water consumption especially in the summer months.
Wood chips/ biomass
Wood chips are one of the best mulches for trees and shrubs, but may not be the best for annuals and vegetables. It has various uses, especially for biomass plants that uses it to generate electricity. It can also be used in landscaping applications as well as nutrifying the soil. As wood chips break down into the soil, they increase soil fertility. Wood chips mulch provides organic matter and add nutrition.Wood chips absorb more water than many other mulches, water which both cools the soil and is slowly released to plants.
Benefits of processing green waste
Reduces bad smells
Reduces greenhouse gases
Boosts soil health
Temperature moderation (blocks the sun and keeps soil cool)
The waste is collected from residential, industrial or commercial areas.
Waste is either taken to a landfill or to our recycling facility where it is separated, baled and resold.
The waste is taken to a licenced landfill site and disposed of in the correct manner.
This is when recovered waste materials such as plastics, paper, glass, metal and cans are salvaged so that they can be reused or resold.
