Afternoon, we bought water tank and pipe connection and made a plan for tomorrow work.
Colomboを朝5時に出発、10時にBawlana Line House Projectの現場に到着。ソーラーボイラーを設置するシャワー室の屋根のコンクリートも打設されており、型枠はまだ外せないが明日から作業ができそうだ。
この後、木下君と貯湯タンク、ホースのコネクションなど必要資材を購入し、明日からの作業に備える。

1) We had a meeting about solid waste management with new commissioner of Kaduwela City Council. They don't have any concept and plan, go with flow.
2) Afternoon, another meeting with トクヒ アプカス staff who have worked for Kaduwela Project. We had discussed why we should make compost from garbage and use to organic farming.

We had visited small organic farmers who will use compost made by garbage. They have farmed rice and small vegetable garden. Organic farmer use glass caver for keeping moisture of land in Japan, but they don't.

We broke the pile of compost that mixed garbage and return compost (1:1 volume ratio) with aeration pipe on August 19th . Aerobic thermophilic bacterium has been breeding at the place of pipes up and down, composting had progressed and you can see actinomycetes.Composting can be in this way, but the pipes were damaged when the round loader break the compost pile.
I had explained about composting to employees who are working in the composting facility. The current situation where internal compost is in the lack of oxygen.
I proposed new method which is loading mixed garbage and return compost (1:1 volume ratio) 25cm depth at one time, and loading it every five days in order to maintain the aerobic condition. The under layer compost get hot when a new compost is loaded, composting speed should go up and facilitate the evaporation of moisture.
The left photo shows compost pile with pipes, right photo shows without the pipe. We have known composting with aeration pipe is good for composting, but decided to try to experiment composting without pipe to cut cost and labor.
The remaining problem is expanding composting space which is keeping rain out. The roof of the extension part will be built this year in the description of Kaduwela City .

We investigated weight of waste which is mixed into the compost. First, the weight of the compost of one bucket was measured.
バケツの中身を床に広げて、非生物系ゴミを拾い出していく。
Then non-biological garbage are picked up from spread compost on the floor.
We measured 12 times, non-biological garbage is average 1.95kg had entered in the compost of average 17kg. Order of frequency, sheet to cover the dishes, plastic back for food, yogurt container, such as plastic spoon.
Total garbage weight is reduced by decompost, but still 11% non-biological waste is high percentage. They need guidance of separation guidance at home, and plastic has to be picked before used for return compost.

日本では夏以外、一般的には温度を上げるためには堆肥の山を大きくし発熱と放熱のバランスを調整して温度を上げるが、スリランカでは温度上昇はそれほど重要でない。
そこで、対策として積み込む堆肥の山を分けて、一度に積む量を少なくし、水分を補給しながら少しづつ積み込むか、エアレーションパイプを利用して内部に水分を補給する対策をお願いしてきた。
In the case of composting of fallen leaves and weeds, the problem is the adjustment of the moisture content, air permeability is not so problem.
While compost moisture increases about 25 cm from the surface in tropical squall, however decomposition of inside compost does not proceed too dry by evaporation due to the temperature rise
To raise the temperature by adjusting the balance of heat dissipation and heat generation to increase the compost pile in except summer in Japan, the temperature rise is not important in Sri Lanka.
Therefore, to reduce the amount compost by divide a pile of compost, you can either load little by little while replenishing moisture, or replenish water to control water content by using the aeration pipe.
下の写真の堆肥は途中で積むのをストップしたため、堆肥の山の高さが20cmだが分解が進んでいる。
In the below photo compost pile depth is only 20cm, but decomposition is progressing.
雑草・落葉の堆肥化は臭いも少ないので快適だ。明日は悪臭の漂う生ゴミの堆肥化の調査に向かう。
It's pleasant to composting of weeds and fallen leaves since it is less odor.

Alan Birch:Economic History of the British Iron and Steel Industry によると Round Oak Steelworks was founded by Lord Ward, later the Earl of Dudley in 1857. と書かれている。この鉄骨は鉄鋼所が1857年にDudley伯爵の所有になった後に生産されたのだろう。
James Taylorが初めてスリランカで紅茶園をこの近くで始めたのが1865年、長屋に住む老人の話では祖父の時代にここにやってきたとのことなので、1800年代後半に長屋が建てられたと思われる。
The steel frame of line house in Bawlana has not much corroded even to have become weather-beaten, there was a mark of EARL OF DUDLEY STEEL.
Alan Birch, “Economic History of the British Iron and Steel Industry” said “Round Oak Steelworks was founded by Lord Ward, later the Earl of Dudley in 1857”. This steel frame might have been produced after the steel plant has become owned by the Earl Dudley in 1857.
James Taylor started Loolecondera Tea Estate, the first Tea garden of Sri Lanka in 1865.
Since his grandfather came here in the story of the old man who lives in the line house, it was probably built in the late 1800s.

若い兵隊がたくさんいるので、労力には事欠かない。後は、やる気だけだが......。
Before returning to Japan, we had seen the compost which was piled in two days ago at Viharamahadevi Park. Since the rain-cover was not shielded, the temperature at near surface had fallen down with rain, but temperature was going up to 60℃ at the center of pile. Subsequently decomposition is in progress and the compost pile is going to be smaller, so fallen leaves and cutting grass should be carried on the pile.
There are many young soldiers, it is not problem of labor.
In the rest, only a motivation is.

Dry compost is spread each time you covered 20cm thickness grass or fallen leaves for moisture content adjustment and seeding.
A ventilation pipe is put on three layers, however fallen leaves and grass were used up, we had to wait to gather material in the afternoon and work was resumed.
