Please find below the first announcement for the 1st International Terra Preta Sanitation Conference, which will be held in Hamburg, Germany, on 29th-30th August 2013 and that might be of interest for the group.

This might also be an opportunity for the WG5 to organise for a working group meeting within the frame of the conference given that we can get a reasonable number of WG5 members together. I would therefore like to ask those of you who are interested to kindly get back to me.

Further information related to the conference can be found below or on the following website: www.tps-ic.org

Thanks and best regards

Can you explain more about what you mean by make the fertilizer? Do you mean the way of processing and do you have any ideas about this, how to do it?

Rgds,

The solution is in how you make the organic fertilizer.
If you have an efficient system you will have more output than from chemical fertilizers.

Sorry no youtube yet. Working on it, so I'll let you and SuSanA know when it is available.

To answer your second question... yes. WASTE is one of the parties that is quite busy raising awareness around the globe for this problem and the need to change policy. Because indeed there are challenges in this area, but as you can see in the movie... the world needs it!

This is mostly because of the fact that the whole picture should be financial sustainable. In some places it is the subsidy, in some places it is the production of some crops that is still higher with the use of chemical fertiliser than with the use of natural fertiliser, or the fertiliser made of human waste IS as good as the chemical ones but it is difficult to produce/handle/manage (separate urine, solid waste collection, upscaling problems).

But this will change soon... even the big chemical furtiliser production campanies are already putting a lot of money in research en development of natural fertiliser. And for example Mars is investing big numbers in this, for the use on their cacoa plantages. The Rabobank and the World Bank have just agreed on a consortium for the finance of the cacoa plattages in Ghana. Some examples of very promising developments are for example Safisana (Ghana) or Soil (Haiti).

This is just to give you an impression about the effort that is made in this field at this moment. Very simply, a the moment it costs money for governments to dispose the waste and furtilise the land. Why would they say no to make money of the waste and furtilise the land for free?

Rgds,

Great video from Malawi comparing the use of organic and chemical fertilisers in Malawi.
Firstly I was wondering whether this video is also on youtube, as it would be great to add it to the SuSanA youtube list of favourites?

Secondly an open question that comes to my mind after watching the video:
Do you think that the use of chemical fertilizer will ever decrease in Malawi and be substituted by organic fertiliser?
As when one considers that the Malawian government has a budget line in the national budget for the chemical fertiliser subsidy programme and that this constitutes 13 to 15 % of the national budget according to the video, this represents clear institutionalisation of the use of chemical fertiliser in the Malawian agriculture sector.

Are there any indications that the subsidy for the chemical fertiliser programme will be decrease or withdrawn by the Malawian government in the future?

I would be very interested to have yours and others thoughts on these open questions.

Rgds

Allow me to give a short introduction. I am Kim Visser and very recently joint the SuSanA network through my new position as a business adviser at WASTE, launching the SANITATION WINDOW: waste.nl/en/project/sanitation-window.

WASTE and Africa Interactive made a short movie about chemical vs natural fertilizers with case studies from Malawi for the purpose of awareness raising about the phosphorus shortage problem.

During the SuSanA meeting last week in Stockholm we also had a brief meeting of the SuSanA WG5 and discussed potential future deliverables of the group. I would like to give you a short summary of what has been discussed:

After the overhaul of the WG5 factsheet last year (as the last main activity of the group) one of the key questions raised was how to reenergise the group and what new deliverables the group could work on next.

We ended up with a nice 'wish list' which included among others:

• A productive sanitation blog that would allow featuring different productive sanitation initiatives and projects worldwide (similar to the emergency sanitation blog of the SuSanA WG on emergency sanitation)
• Inventory of existing productive sanitation initiatives, experiences and current research
• A guidance document on logistics and reuse of faecal sludge from wet systems
• Development of a new WG5 factsheet supervised by the Swedish University of Agricultural Science (SUAS) that should give an overview on different sanitation waste streams and products and their characteristics and agricultural potential
• Policy promotion
• Organizing joint video conferences on specific productive sanitation related topics using Google+ hangout

The following concrete activities have been identified as immediately feasible:

• Adding a WG5 blog section into the SuSanA forum where people are encouraged to post their current productive sanitation related activities, ongoing projects, related research activities etc. (Linus Dagersgog and I will develop a list of criteria that might be helpful in giving some guidance on what aspects should/could be covered in the blog entries)
• Frank de Ruijter is currently applying for a fellowship at the Swedish University of Agricultural Science in Uppsala. Given that his fellowship will be approved he will develop a paper where he will look into different sanitation waste streams and products and their characteristics and agricultural potential. This could become a potential second factsheet of the WG5. As soon as the paper is developed we are planning to share it with all of you and incorporate your inputs and feedback.

In case you would like to volunteer to work on one or more of the other above mentioned deliverables from the wish list or if you or your organisation are currently working on additional products that could potentially become a deliverable of the WG5 please kindly let us know.

And particularly to those who participated in the WG5 meeting last week: Please feel free to comment or add things that I might have forgotten.

Best regards

rob

Thank you for answering my questions thus giving me more insight. A country produces "X" amount of Phosphate Rock (as P2O5) and "Y" amount of fertilizers (as P2O5). Then, what represents the difference between the quantities X and Y i.e. X - Y ? Phosphate which goes to manufacture detergents? or mining losses (e.g. phosphogypsum)? mining wastes?
2. Is it possible to quantify phosphate mining losses? phosphate mining wastes?

Kind regards

To answer your observations.
1. The solar on/above the roof is PV as one needs electricity for a heating element in the base of the biogas reactor to create thermophilic fermentation. This will substantially speed up the digestion and allows the reactor to remain small and yet discharge pathologically purified effluent.
1. The solar drier is to dehydrate the liquid effluent to make dry compost. This requires quite some space and can be a small business outside: transport, drying, packing from many units is more efficient than each for itself. The roof space is needed for hydroponic vegetable growing.
2. Grey water and urine can indeed be used in the roofgarden and facade gardens. I would imagine that grey water is preferred and urine is cristallized off-site also as a business.
3. The kitchen waste and woodfibre toilet paper are required to balance the C/N value of the slurry for optimization of gas output. Once the faecal matter has gone through the double biogas reactor under thermophillic conditions it is phatologically clean. One can apply the slurry also directly to agriculture. Further sundrying of the effluent (outside the village) will produce transportable bags of compost.
4. If someone will implement the proposal I will work it out.
5. Biogas operation is in the groundfloor (compartments) only. From the upperfloors the piping goes down.
I worked three years in biogasprojects.]]> WG 5 (productive sanitation) Thu, 02 Aug 2012 15:15:02 +0000 http://forum.susana.org/forum/categories/58-wg-5-productive-sanitation/205-update-of-susana-wg-5-fact-sheet-food-security-a-productive-sanitation?limit=12&start=12#2020 http://forum.susana.org/forum/categories/58-wg-5-productive-sanitation/205-update-of-susana-wg-5-fact-sheet-food-security-a-productive-sanitation?limit=12&start=12#2020
Thanks for your urban concept drawing. My favorite aspects of it include the plants growing on the outside of vertical walls and the use of solar driers.

Please allow me to make a few comments and suggestions.

1. Why not put the solar drier (or oven) on the roof to economize space on the land?
2. The vertical garden could receive a percentage of the urine and greywater.
3. I would not prefer to mix toilet and kitchen wastes, to keep the fecally dangerous material as small as possible. This mixing could happen after the feces are made safe by one method or another.
4. Some of the features are hard to understand, so it may be good to make a clearer draft, possibly including an accompanying text with explanations.
5. How can the biogas operation be in the penthouse?

The difference is because they are different products with different phosphorus content.

There is no reference to waste in the link? Can you clarify what you mean by waste?
