Global waste grow more then 70 percent by 2050

And by 2050, waste generation in Sub-Saharan Africa is expected to more than triple from current levels.

Plastics are especially problematic. If not collected and managed properly, they will contaminate and affect waterways and ecosystems for hundreds, if not thousands, of years. In 2016, the world generated 242 million tonnes of plastic waste, or 12 percent of all solid waste, according to the report.

What a Waste 2.0 stresses that solid waste management is critical for sustainable, healthy, and inclusive cities and communities, yet it is often overlooked, particularly in low-income countries.  While more than one-third of waste in high-income countries is recovered through recycling and composting, only 4 percent of waste in low-income countries is recycled.

ARC-AE researcher released draft digestate report

Digestate holds many advantages

Researchers at the ARC-AE are going to great lengths to develop and promote crop cultivation and healthy soil properties using digestate. Any anaerobic digestion creates an end product called ‘digestate’, which will typically constitute 90-95% of the unconverted feedstock material. The anaerobic digestate makes an excellent renewable (green) fertiliser, with better characteristics than organic compost.

Integrated field experiments were recently conducted at various sites to ascertain digestate’s effects in comparison with chemical fertiliser on agricultural crops’ yield and profitability.

Crop yields were higher for plants grown with digestate compared to other fertiliser treatments. In addition, our analysis showed that the highest gross return was obtained from crops treated with biofertilisers. However, application of synthetic fertiliser in combination with biofertiliser can potentially increase crop yields and the subsequent economic return.

Different growth stages of beans with digestate application.

In conclusion

Our natural scientists, engineers and agricultural economists are working hard towards the establishment of protocols and mechanisms for end users. Some of the vital information an end user needs to know about are the following: storage, spreading strategy, application rate, properties of digestate and crop type, and time of application. – Dr Idan Chiyanzu, ARC-Agricultural Engineering

 

Trash is gold’ as Benin community turns waste into biogas

Garbage has never smelled so sweet for a small village in southern Benin since it opened a pilot waste treatment centre to turn household rubbish into gas — and cash.

After we separate the waste we can use the organic for energy production. Waste to Energy is the cheapest and environmental friendliest way to keep our country save and healthy.

Joburg will make household recycling compulsory from 1 July

​In an effort to cut down on pollution and safeguard the environment, the City of Johannesburg will roll out a phased approach to make separation at source…

Biogas is one of the best solution to get organics off the landfill and biogas produce fuel for busses, cars and heating the house.

Biogas works for small Piggeries

Biogas can not only offer you a opportunity to reduce your energy cost but also offers a proven environmental management solution for pig slurry.

Benefit for you:

  • Generate renewable energy that will:
  • Reduce cost of utility electricity usage (Eskom account)
  • Generate heat that can be used in piggery – saving fuel cost for heating
  • Give security of supply (own generation capacity – managing load shedding)
  • Replace fossil fuel with natural renewable fuel
  • Reduce carbon foot-print via greenhouse gas reduction
  • CH4 reduction which is 21 x more harmful than CO2
  • Reduce by-product management and handling cost
  • Reduce solid content of slurry with at least 70% allowing it to be put directly into a irrigation system
  • Improving the bio security of pig slurry
  • Save water
  • Generate a safe green bio-fertilizer
