Waste Management Ideas

  

As discussed previously, the waste generated during cassava processing is very detrimental to the environment and there for a high importance should be placed on the implementation of proper disposal or alternative uses. From research it was found that both liquid and solid waste generated can be transformed into materials which can be put to better use. In the chart below a brief outline of the possible applications of the waste is given:



  • Cassava peels: after the cassava is peeled, it was found that activated carbon was produced from them which is effective in the treatment of water containing heavy metals among other toxins for both oily and non-oily waters
Other possible applications:
  • cassava is also rich in nutrients such as nitrogen, phosphorus, potassium and magnesium, leaving opportunity for the application as a fertilizer which will enhance the crop production and aid in supplementing the demand of nutrients to an extent. eg. manipueira was used as a fertilizer for sunflower cultivation which produced satisfactory results

  • Taking into the consideration the negative impact of synthetic pesticides on the environment, natural pesticides are being researched:

  1. evidence that cassava wastewater powder-based solutions are efficient in killing aphids
  2. cassava wastewater could successfully reduce cutting ant populations by up to 80%
  3. wastewater appears to be recommended for the control of bacterial plant diseases

Cross-contamination in Food processing Plants

Cross-contamination in food processing facilities can occur in ways that may not even be visible as  there are many unexpected ways in which bacteria can travel. Awareness of these potential causes of cross-contamination will aid in the maintenance of a sanitary food processing environment . Post-Harvest Contamination Workers that go from the area of sorting the raw material upon arrival to processing zones are susceptible to spreading bacteria from unclean hands touching food or food-contact surfaces. Cross-Contamination from Storage Bins Stacking storage bins directly onto soil or areas outside the processing facility and then bringing the containers into the facility can also bring bacteria into a clean environment.   Contamination from Footwear When employees walk in fields, compost sites, or other areas outside of clean zones, they can bring bacteria into a processing facility on their feet.    Contamination from Mobile Equipment The same challenge a...
