Bamboo to the rescue

The results of an EU-funded project to treat waste water with bamboo are now being marketed. The project established the market viability of intensified bamboo-based phytoremediation for dairy and other food industry grey water applications. In other words, a bamboo forest can treat industrial discharge on a large scale.bamboo forest

The French company Phytorem is selling the managed process as the Bambou Assainissement (bamboo sanitation) filter. The process can be scaled for both domestic and industrial waste water, and is suitable for hotels, camp sites, retirement homes, housing estates, isolated infrastructures, wildlife parks, landfills, storm water and more.

Multi-purpose bamboo forest

Phytoremediation is essentially vegetation filtration. In this case the vegetation is a bamboo forest. Bamboo is well-suited because it has a very dense root system, is fast-growing, and suited to a wide range of climatic conditions. In addition, the bamboo can be harvested for fuel, construction, furniture, textiles or paper, just to name a few uses. The Phytorem web site also suggests food, but I’m not sure I’d be keen to eat bamboo shoots grown in industrial waste.

Of course, the use of phytoremediation has limitations. An EPA paper outlines some of the limitations and disadvantages for the broad process of phytoremediation. They include: depth limitations of the plant roots; the process is slower than other treatment methods and dependent on growth rates; leaching of contaminants into the groundwater and environment; and, accumulation of contaminants that may pass into the food chain. The many unique properties of bamboo, however, overcome some of the disadvantages of other types of vegetation used for phytoremediation. It gives me hope.

Do you have any experience with bamboo as a grey water treatment?

More on harvesting and storing bamboo

It’s now a month since I cut a selection of bamboo. The process was described in the World Bamboo Day post. The culms were all left upright in their respective groves, propped up off the ground by various means. harvestingpostSome had stones under them, others were held off the ground with bricks or blocks. Some sat quite neatly over, or in, the stump of a freshly cut neighbouring stem of bamboo. After a month of transpiration, this week I removed the cut bamboo from one grove.

After a month, the leaves are dry and crisp and brown. harvestingtranspThe top sections of each culm, where the branches start, are changing colour to yellows and browns. Below the branches, the colour on the lower parts looks to be pretty much the same as when they were cut. Unsurprising, given that this is where most of the  moisture is stored. I cut each stem just above the lowest branch and discarded the upper section with all the branches.

This sudden influx of bamboo culms has created an urgent need to get creative with storage solutions. The bamboo needs to be out of the weather, in a covered area, and off the ground. My storage solution?

Hang them from the rafters

Storing culmsI’m very fond of simple, practical solutions to any challenge or problem. To create an additional area to cure and store the freshly cut, slim and light bamboo culms I used some silver rope and short lengths of bamboo. Like a series of swings or trapezes. This system will be easily expandable.storage culms

Taiwan → bamboo → Bamboola

At Zhushan bus station

At Zhushan bus station

On a trip to Taiwan earlier this year, I was keen to get to Zhushan to visit bamboo craftsman Liu Wen-Huang and his Bamboola workshop. Like other parts of Taiwan we visited, from the time we arrived in Zhushan, kind and friendly local folk went out of their way to assist us. And we needed a bit help. Arriving at the bus station, we found that the Information Centre had closed down and we no idea how to find Mr Liu. A departing bus was delayed while an English-speaking woman helped us contact the workshop. No one seemed to mind.

Mr Liu’s wife collected us from the bus station and drove us to the workshop. On arrival we were offered green tea and invited to open the puzzle boxes. We failed.

The showroom is full of beautifully finished items of original design. Although travelling light, some purchases could not be resisted. Among other things, my travelling companion purchased a set of tea trays and I took home a tea canister. The lid fits with precision and gives an excellent seal to keep tea fresh.

We were just about to be rushed off to the bus station to get the last bus of the day to Xitou, when Mr Liu himself arrived and instantly offered to drive us to the accommodation his staff had kindly arranged for us in Xitou. This gave us time for a factory tour.

The factory is high tech. Ideas are developed using specialised computer programs and the laminated bamboo sheets (currently manufactured in China with moso bamboo) are cut with precision by computerised cutting machines. Mr Liu demonstrated the computer programming he uses with a current special project of 5 km of curved book shelves for the National Taiwan University library. Awesome.

Mr Liu then drove us through some very steep back roads to the Ginko hotel in Xitou. The 40 minute trip was very scenic. We passed many moso bamboo groves growing on the steep slopes. Upon arrival we took refreshments with Mr Liu, his wife, and their friend the hotel manager before they left to drive back to Zhushan. Our stay in Xitou warrants a bamboo story in its own right. For another post.

Drill bits for bamboo

Spur and screw point

Spur and screw point

Drilling holes in bamboo is not like drilling holes in wood. With the right drill bit a clean hole can be drilled. A drill bit with a spur, or wing, pre-cuts the bamboo, while the screw point keeps the drill bit where it is needed instead of sliding around on the smooth surface.

Messy exit wound

Messy exit wound

However, drilling right through a round piece of bamboo results in an messy, splintered exit wound where the smooth outer surface outer coating is cracked and split – no matter what drill bit is used. This is a problem discussed at length in a thread on Bamboo Forums if you’re interested in following the discourse.

Star-M packet

Bamboo is NOT kind to drill bits. Of the 2 drill bits I purchased – 4 & 6mm – the 6mm bit turned out to be one I used most, so it rapidly became blunt. The silica outer coating of bamboo blunts drill bits and knifes much faster than wood does.

At my request, some drill bits just arrived from Japan (Thanks Chris!) – I couldn’t find anything similar to replace the 6mm Star-M drill bit I purchased in a VERY large home improvement store on the outskirts of Tokyo this time last year. You can read about the Star-M drill bits in English here.

The freshly arrived drill bits were of two lengths – 16 cm, and the more standard 9cm. Left to my own devices, it would not have occurred to me to buy a 16cm long drill bit, but the long one was instantly handy for drilling straight through the rather scrappy and dry large bamboo that supports the seasonal shade cloth for the vege garden. Straight through. No more need to guess where that hole on the other side of the bamboo should be. (Thanks, Chris).

Have you got a friend in Japan who can dash off to the local hardware to pick up some drill bits for you? (Thanks again, Chris). No? I’m sure you can find them online.

Bamboo leaf tea – part 2

A friend and fellow blogger in Japan was kind enough to send me links to some Japanese blog posts about bamboo leaf tea. (Thanks, Megumi!). So, following on from Bamboo leaf tea -part 1, here is some how-to (with the aid of Google Translate) for making your own bamboo leaf tea at home.

The instructions in the blogs are similar and use Kumazasa, a bamboo that grows in Hokkaido. In fact, Kumazasa is something of a Hokkaido speciality and is sold as tea (loose leaf, tea bag, and canned drink), granulated extract and candy. Bears are also very fond of Kumazasa bamboo.

World Bamboo Day, 18 September

wbd_logo_onecolor_alt_thumbWorld Bamboo Day is a day of celebration to increase the awareness of bamboo globally. In the week leading up to World Bamboo Day I’ve been harvesting bamboo inside the very large stands of one of the smaller kinds of bamboo here.
