Re: [Biofuel] Fwd: Information on Sawdust processing
hello. just another environmentally friendly glue: - Tanzania industrial research and development organization (TIRDO) in collaboration with FORINTEC of Canada developed a water resistant (up to boiling) glue ideal for plywood and particleboard manufacturing. main ingredients being cashewnut shell liquid and wattle tannin, while other additives being urea-formaldehyde (UF), coconut shell flour and castor oil. the product was applied at a particleboard factory and performed to satisfaction. more details can be enquired from [EMAIL PROTECTED] Lugano Friedrich Friesinger [EMAIL PROTECTED] wrote: Hi Luis, the cheapest Glue would probably a Kaseinglue be! 9parts withe chease and one part chalk mixed with water and thinned out well!

Re: [Biofuel] Fwd: Information on Sawdust processing
Dear Fritz: Sawdust and another fibrous waste, such as sugar cane bagasse yield excellent boards as well as briquettes. I will give a try to both products. The choice of binders is important, since one would like to stay away from formaldehyde based glues. Another binder I will try is a lignin based type. For the benefit of everyone I will publish my results. Thanks very much and take care, Luis R.

Hello I am new to the list (couple days). So far I am reading and learning but I have some experience in the wood processing sector. I am not sure about the quality of the sawdust but I wouldn't dump it. It can be used for particle boards. I have managed a project where we have doen electrical work and automation for an entire particle board plant. It is not a cheap process but worth to look at . Basic steps are: - Dry the saw dust, - Prepare the glue and mix with the saw dust - Lay the sawdust on a conveyor belt - Press the saw dust and heat it - Cut into the dimensions you need. If the saw dust is fine enough it can be used for making MDF (medium density fiber board). Which is a valuable product. Hope this helps.

Re: [Biofuel] Fwd: Information on Sawdust processing
Greetings from Sri Lanka, Dear Burak Cedetas, Thank you so much for the innovative suggestion..We are also thinking of a similar method to make some boards. Here we plan to experiment with Latex, using latex as a binder. We have not tried it yet. Can you be so kind to send us the process that you are using to make the particle boards please. It would help us to compare notes and see which is more inexpensive. On the other hand, we are thinking of introducing, sort of a home industry through which the people could earn an income. If people see that they could make an income, then they will take it up. Since the target group is women and from the low income stratum the process has to be simple and adoptable to them. Thank you once again for your kind concern on this matter.

RE: [Biofuel] Fwd: Information on Sawdust processing
Dear Luis, I was not suggesting fuel logs. My suggestion was to produce partcile boards or mdf boards with the saw dust. Of course this depends on the phsyical measurements of the saw dust. But to make particle board plants take the logs breaks them apart to form particles so to speak. In this case since the wood is already in form of saw dust this can be used right away. If it is a fine saw dust than a possible mdf production may be a good idea. The glue to be used for this process I have to look for. It was a form aldheit or similar but again I have to check with the plant we have done the project for.

RE: [Biofuel] Fwd: Information on Sawdust processing
Hi, I would agree. Also sawdust boards continue to emit formaldehyde and other noxious chemicals that are linked with cancer. They are used in lower end furniture, cabinetry, countertops etc and continue to release a toxic mix of stuff into your inside air. If you are going to use a bonding agent for the sawdust, I would do some exstesive research on an environmentally friendly way to do this.

For a developing country like ours this type of spending is unaffordable. Truly a huge waste of a very valuable resource. What an unnecessary, avoidable and costly expense for dumping/disposing of this waste! And the pollution. We have been trying to find a solution to re-cycle and use saw dust. As we understand, it is possible to make Sawdust Bars - fire logs, briquettes etc or even insulating boards if properly experimented. We were also made to understand that there are many organisations, private sector companies engaged in this business. A good idea would be to convert the saw dust into fuel briquettes using either punch-and-ram or extrusion presses. The briquettes from the former cost less to make while those from the latter retain their structural integrity better over time. The fuel briquettes could be used as fuel in the local rural economy replacing logged wood/coal/paraffin. We have a large number of briquette manufacturers in India. However, since densification of biomass (which is what briquetting does) adds only limited economic value by reducing specific transport cost without adding to the calorific value, they have limited markets in tea/coffee plantations, where felling of alternative biomass such as trees is banned, to prevent landslides. We thought of searching for a simple technology that could be introduced to the low-income generation groups in the area, especially to the women, who could produce some type of an item to the market, could be a fire log, a briquette or an item that could be used in daily life. The saw dust briquettes could be very gainfully converted into high quality energy such as producer gas to replace fossil fuels, or as electricity. Gasifiers use the briqettes as feedstock, when solid biomass is converted into producer gas viz. a mixture of combustible gases such as H2, CO, CH4 and inerts such as CO2 , N2. The producer gas is then cooled, cleaned and used in conventional (compression ignition) diesel generators replacing about 70-80% of the diesel otherwise used in the liquid fuel mode. Alternatively, the gas can be used to generate electricity in the gas alone mode using spark ignition natural gas engine generators, with special adapation kits to operate on producer gas. In a developing country such as Sri Lanka with limited fossil fuel resources, the generation cost of electricity would be significantly higher in the dual fuel mode with imported diesel compared to the gas alone mode with locally generated biomass. Such a 100% gas engine based power plant would have a number of advantages. The electricity required for the briquetting plant could be supplied from the power plant itself, adding to the green dot nature of the plant. The plant can be configured from 20 kWe to 2000 kWe capacity, depending upon saw dust generation and the local power requirements. Electricity would be generated at the pit head avoiding the transmission and distribution losses of centralised power grids. And the gasifier power plant would be a force multiplier for the local economy whose needs are now met with local fuel. The other inherent advantages such as pollution avoidance and saving in disposal cost and effort cannot be overemphasised.

There are large numbers of timber mills, carpentry workshops and woodwork centers in the area. They produce tons and tons of saw dust and dump them into the nearby lake polluting the area. Recently the government has no other alternative, but found another dumping site and the sawdust is now dumped in this site spending large sums of money for transportation. For a developing country like ours this type of spending is unaffordable. Truly a huge waste of a very valuable resource. What an unnecessary, avoidable and costly expense for dumping/disposing of this waste! And the pollution. We have been trying to find a solution to re-cycle and use saw dust. As we understand, it is possible to make Sawdust Bars - fire logs, briquettes etc or even insulating boards if properly experimented. We were also made to understand that there are many organisations, private sector companies engaged in this business. A good idea would be to convert the saw dust into fuel briquettes using either punch-and-ram or extrusion presses. The briquettes from the former cost less to make while those from the latter retain their structural integrity better over time. The fuel briquettes could be used as fuel in the local rural economy replacing logged wood/coal/paraffin. We have a large number of briquette manufacturers in India. However, since densification of biomass (which is what briquetting does) adds only limited economic value by reducing specific transport cost without adding to the calorific value, they have limited markets in tea/coffee plantations, where felling of alternative biomass such as trees is banned, to prevent landslides. We thought of searching for a simple technology that could be introduced to the low-income generation groups in the area, especially to the women, who could produce some type of an item to the market, could be a fire log, a briquette or an item that could be used in daily life. The saw dust briquettes could be very gainfully converted into high quality energy such as producer gas to replace fossil fuels, or as electricity. Gasifiers use the briqettes as feedstock, when solid biomass is converted into producer gas viz. a mixture of combustible gases such as H2, CO, CH4 and inerts such as CO2 , N2. The producer gas is then cooled, cleaned and used in conventional (compression ignition) diesel generators replacing about 70-80% of the diesel otherwise used in the liquid fuel mode. Alternatively, the gas can be used to generate electricity in the gas alone mode using spark ignition natural gas engine generators, with special adapation kits to operate on producer gas. In a developing country such as Sri Lanka with limited fossil fuel resources, the generation cost of electricity would be significantly higher in the dual fuel mode with imported diesel compared to the gas alone mode with locally generated biomass. Such a 100% gas engine based power plant would have a number of advantages. The electricity required for the briquetting plant could be supplied from the power plant itself, adding to the green dot nature of the plant. The plant can be configured from 20 kWe to 2000 kWe capacity, depending upon saw dust generation and the local power requirements. Electricity would be generated at the pit head avoiding the transmission and distribution losses of centralised power grids. And the gasifier power plant would be a force multiplier for the local economy whose needs are now met with local fuel. The other inherent advantages such as pollution avoidance and saving in disposal cost and effort cannot be overemphasised. (Below, In Rs. stands for Indian Rupees, SL Rs. is Sri Lankan Rupees and US c and $ are United States cent and dollar resp.) Assuming the delivered cost of saw dust as zero (savings in disposal cost), the briquetting cost would be about $ 10/MT

Re: [Biofuel] Fwd: Information on Sawdust processing
I use the same kind, no binder made briq's, for the bulk of my winter heating. Less than 2 kg of these briq's are the thermal equivalent of one litre of heating oil. I need about 1 metric ton per winter, and it's 3 times cheaper than heating oil per kWh of heat. The shawings and sawdust are produced in a woodworking shop that makes parquette flooring, the briq's are just a byproduct to get rid of the shawings and dust.

For indeed, thanks to widespread and sustained media attention, activists and NGOs have been able to garner support pushing for the conservation of the Bolgoda Lake and its surrounding wetlands. The uncontrolled dumping of industrial effluent, agricultural pesticides and untreated sewage leading to depleting mangrove reserves and the immense loss of biodiversity, an ever-increasing population density due to its recreational value and scenic beauty, and now the construction of the Colombo - Matara Expressway to join the long catastrophic laundry list, inevitably prompts socio-environmental calls-to-action. An entire eco-system is in peril. That was what it was called before, and quite rightly too.

Dear Sir/Madam, Ours is a Non-governmental, non-profit making organisation devoted to development through self-help development programmes. We also carryout environmental protection programmes with local communities in Sri Lanka. Recently we were informed of a long-standing problem in a suburban city, due to sawdust. There are large numbers of timber mills, carpentry workshops and woodwork centers in the area. They produce tons and tons of saw dust and dump them into the nearby lake polluting the area. Recently the government has no other alternative, but found another dumping site and the sawdust is now dumped in this site spending large sums of money for transportation. For a developing country like ours this type of spending is unaffordable. We have been trying to find a solution to re-cycle and use saw dust. As we understand, it is possible to make Sawdust Bars - fire logs, briquettes etc or even insulating boards if properly experimented. We were also made to understand that there are many organisations, private sector companies engaged in this business. We thought of searching for a simple technology that could be introduced to the low-income generation groups in the area, especially to the women, who could produce some type of an item to the market, could be a fire log, a briquette or an item that could be used in daily life. If we could introduce this type of a technology then it will help the poor to generate income. On the other side it will arrest the pollution problem in the area and save public money that is spent at present for clearing and dumping. Considering the above we are very much obliged if you could help us in finding a technological enterprise who would willing to conduct an investigation on this matter. Since ours is a NGO, we are unable to fund such a programme. If the programme proves to be successful, we may be able to convince a suitable and sympathetic funding agency to support the initial stages of this challenging project.

Re: [Biofuel] Fwd: Information on Sawdust processing
Combine sawdust with hacked rice straw (about 2 in long) as a filler and mix in poor concrete or concrete milk. Cast porridge in wooden forms (blocks several inches or panels desired inches thick) and use for insulation between rafters. Straw panels made this way are still widely used in Slovenija (sandwich : cast porridge- styrofoam-cast porridge). Blocks are held together with cement mortar, panels are screwed ot nailed to the construction. Plaster on both sides and you've got a nice wall with some thermal mass, or don't plaster and just paint and you get a nice rustic wall. Alternatively combine sawdust and hacked rice straw with clay to make plasters, bricks, cast walls (an adobe variation, is it?). Depending on climate, outer walls made this way should be protected by suitable overhangs. Sawdust by itself could make insulation in hollow spaces in walls, but should be treated with perborate to fireproof (nontoxic). All this can be made by hand. If funding kicks in, buy hydraulic press for wood bricks, doesn't need binder but a lot of pressure (power, this can't be made by hand). Aleks Greetings all I was sent this by an NGO in Sri Lanka.

Hi Keith, is there any information about quantitys and kind of sawdust availible? These poeple shold first look for a site where they can collect the Sawdust, i presume,the Sawdust is from green Lumber,mostly exotic species,wich have a devastating effect ,dumped in Water!But Sawdust is a verry good resource to make Woodbriquettes or Pellets and brougth to the markets!There are different possibilitys to make low cost Briquettes or Firelogs.I would need a bit more info about Thanks for posting this topic Fritz - Original Message - From: Keith Addison [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, October 27, 2004 1:42 AM Subject: [Biofuel] Fwd: Information on Sawdust processing Greetings all I was sent this by an NGO in Sri Lanka.

Re: [Biofuel] Fwd: Information on Sawdust processing
hello Keith, it is also possible for the rural poor to utilize the sawdust directly for their daily or mini commercial cooking by utilizing sawdust stoves. the stoves will generate enough heat for even elongated cooking periods using various size of pots, etc. the boiling point journal could be a good source of information for this - search at http://www.itdg.org/ Lugano.

Re: [Biofuel] Fwd: Information on Sawdust processing
One of the thing I am thinking about, is that the additive / adhesive would add heating value, and make it easier to ignite. Using a natural adhesive, the amount of compression needed to hold the sawdust in shape would be less, in fact could easily be obtained with a press made from scrap metal.One thing the adhesive would also do is add some tendency to repel water and insects.
