S3IC / JADE Project/ Report S3IC, No. S3IC-2009-001/ Montreal, February 2009 1 Transforming invading plants into fuel pellets in Ross-Bethio (Senegal) Amadou Oury Ba1, Ndiogou Diongue1, Abdoulaye Fall1, Mamadou Aly Sow1 , Benoit Courteau2 et Djibril Diao3Abstract - This article deals with an integrated project that produces fuelpellets, bio-compost and bio-fuel. Such a study is done by S3IC and itspartners in Ross-Bethio, Senegal. This first stage of this project financed bythe World Bank as Development Market Place 2006 (DM 2006), is abouttransforming invading plants (Salvinia Molesta, Typha, Khaye) on thebanks of Senegal River into fuel pellets for the rural population use in mealcooking. First of all, the article introduces the issue of the initial project andpresents the production line (composed of tools used to cut plants, a pelletpress, a bio-fuel engine and a shredder) designed by the project team toproduce those fuel pellets. Then, the article displays the vision and theimplementation of this integrated project from the experimental stage of the a) - Salvinia Molesta b) - Typha Australisunit to its profitable trading stage and throughout its transitional stage,which is necessary to the accomplishment of fundamental conditions. Theauthors end up the article by presenting the main social, economic andenvironmental advantages of the products (fuel pellets, edible pellets, bio-compost, bio-fuel), that will be gained from the future integrated salebusiness with social advantages.Index terms - Salvinia Molesta, Typha Australis, Khaye, Jatropha, carcus,fuel pellets, edible pellets, bio-compost, bio-fuel, grapnel, pellet press,shredder, bio-fuel engine, etc. c) – Invaded irrigation canals1 - INTRODUCTION Figure 1.1: Invading plants in canals and/or streams of waterJADE project (or DM 2006 Project 1075 of Development 2 - INTRODUCTION OF THE PILOT PRODUCTION UNITMarket Place) of the World Bank which was initially meant totransform Salvinia Molesta (or water Hyacinth) intoecological fuel became along its process a project oriented The objective of this pilot phase of the JADE project is totowards valorizing invading plants and agriculture residues. transform invading aquatic plants in the valley of SenegalThis experimental stage of the project is managed by S3IC1 in River into compost and fuel pellets for domestic cooking. Thecollaboration with Ecoindutrielle2 its Canadian partner, and production of cooking pellets is made from a mechanicalASESCAW3, its Senegalese partner. So, the project targets an equipment (fig.2.2) which is a set composed of a shredder andarea around the Senegal River (initially around Ross-Bethio), a rotary pellet press (PP) driven by a Jatropha (Kîdy ora place overwhelmed for many years by aquatic plants tabanani) oil engine. Therefore, we intend to grove a few(Salvinia Typha, Khaye, and others) (cf. figure1.1) that acres of this plant in the project frame work (cf. fig.5.1).prevent livestock from drinking, and fishermen from working Before taking them to PP, the invading plants are previouslyproperly. All this contributes to the degradation of water shredded; the obtained flour is put in a sieve (which will bequality of the river and the blockage of the soil and draining later on replaced by a grindstone) so as to retain the biggestsystem. particles. The finest particles are then mixed up with water and this aqueous mixture will be introduced in the PP to produce fuel pellets by extrusion.1 - S3IC : Société Sénégalaise des Scientifiques et Ingénieurs au Canada, 8243, Rue St-Denis, Montréal (Qc), Canada, H2P 2G7.2 - EcoIndustrielle : Une Division de Mécanique Industrielle, 569-F Boul.

S3IC / JADE Project/ Report S3IC, No. S3IC-2009-001/ Montreal, February 2009 22.1- Tools used to cut the invading plants In their first proposal to the World Bank, the authors weresupposed to use the grapnel to clean stream borders andirrigation canals in the valley of the Senegalese River.However, if the grapnel is useful to pull Salvinia Molesta, ithas revealed itself not efficient enough against Typha orKhaye which are deep rooted plants in water. Against the a) – A view of the Grapnel b) - Grapnel in uselatter plants, the authors have used scythes and sickles which Figure 2.1: Grapnel in use within a Salvinia environmentwere more efficient. In that respect, CSS (Senegalese SugarCompany) planting many acres of sugar cane, uses‘focardeuse’ machine to cut and clean stream borders andirrigation canals. Photos in Fig.2.1 show grapnels in action.2.2 - Components of the chain of the unit productionAs mentioned, one of the goals of the project is to transformenvironmental waste of invading aquatic plants into fuel fordomestic cooking. In that respect, it was necessary to dry, a) - Pellet Press (PP) b) - Shredder for dry vegetal matterscrush, grind up, optimize parameters (optimum composition ofthe initial mixture, size of the pellet, humidity, etc.), andextrude the vegetal matter to make fuel pellets. The sun driesit, a shredder cuts it into thin particles, a spraying system isused as humidifyer and the rotary press works continuously toproduce pellets.The Pellet Press (PP) is made of a series of pierced platesturning around a compressed wheel that forcefully drives thevegetal matter, inserted into a silo, through holes. The wholesystem turns slowly (35 to 40 rpm) and needs less energycompared to the hydraulic system. The whole set is 1.5m x1.5m x 0.5m of volume and 350 Kg of mass. The PP operateson the principle of extrusion which requires 10 metric tonsforce to put participles together in such a way to produce acylinder of 6 mm of diameter. The PP is a machine whichoperates continuously (cf. fig.2.2a). c)- Main components of the unit The Bio-fuel engine - the PP is driven by a 20 horsepower(hp) diesel engine; half of this power is used to turn on other Figure 2.2: Components of the pellet production unitcomponents such as the shredder or generator. The dieselengine operates on our own bio-fuel. We are completing a 2.3 - Operating the production chainmethod to make sure of the reliability on the way the dieselengine operates (fig 2.2c, in red). Once harvested either by grapnel or by scythe, plants are The shredder- is a rotary device with hammers which dried on the spot and roughly cut into 1.5m pieces in size so asrequires less than 5 hp in order to operate. The equipment is to handle them easily. Stems are then mechanically shreddedcomposed of a clutch and different internal sieves with (2mm, and manually sieved to get the size of the pellets as specified3mm and 4mm wide) allowing different sizes in grind. The previously. The grind matter is thus weight and spread on araw material is introduced through the happer, it is shredded plastic sheet. It is sprayed with a known volume of water inand ground up by the hammers speeding at 4000 rpm, it is order to get the right humidity content to make pellets. Theroughly sieved and then driven out and put in a bag (see fig. whole grind is covered for a while to allow water to soak in2.2b). (cf. photos of fig.2.3). Then, the humidified grind is put in the Sieve versus grindstone - Now, we are using a sieve to supply silo of the press. The compressed grind is driven intoobtain thin particles, necessary to produce pellets. However, the plate holes and becomes a cylinder of 6mm in diameterin case of ultra thin grind, it would be possible to think about which falls off when it reaches 5 cm in length. The output isadding a grindstone in order to transform thin particles into collected under the PP machine, and then dried in order to‘flour’. The principle this grindstone is operating is similar to restore the humidity content it requires to burn. So, pellets arethe system that helps transform grains into flour. ready to be used (cf. fig. 2.4).

This method is itself derived from the D240produce fuel pellets. The unit was composed of a rotary pellet method by the American Society for Testing and Materialspress driven by a diesel engine running on biofuel and a (ASTM) called ‘ Heat of combustion of liquid hydrocarbonshredder for dry material. Since the particles coming out of the fuels by bomb calorimeter’.shredder were big enough, the use of a sieve was necessaryfor the time being as the required improvement will be madeto the device later on.

A sound network of business distribution and sale - In order to be a viable one, any company must have a sound business network of supply and sale. It would be also important to set up such a network in a way that suppliers would be able to put the vegetal pellets produced by the company in most of the shops as well as the stocking places for charcoal. For example the groups of women who are currently in charge of charcoal supply could constitute a starting network in receiving the pellets. 4.1.2 - Technical conditions An available bio-fuel- The use of an engine running on biofuel is one of the conditions for the project to be profitable economically and to be acceptable ecologically. However, there is not yet an organized production unit using oil in Senegal, despite the existing PROGEDE project own by the government which has already provided acres of land in order to plant Jatropha carcus. That is the reason why since its experimental phase, the JADE project has managed to create a nursery of plants and to start planting them (see Fig. 5.1). Since the plant only yields its seeds after a two year period of existence, the issue of mechanically transforming grains in cooking oil ought to be solved. For the time being, one of rare source of supply in Jatropha oil is a traditional method of production. It would be therefore necessary to think about a supply channel from neighbouring countries such Niger, and mainly Mali which is in advance in the growing of the plant. A technical capacity to produce pellets continuously- The current level in the technical capacity for the experimental production must be reinforced if we want to reach the phase of a profitable business production. In that respect, significant improvements and technical tests must be performed in order to go from an experimental run business to a profitable business. All these improvements should take place during the transition phase. Figure 4.1: Vision of the implementation of the sale unit Therefore, this sale production unit could very soon becomean integrated company type whose products would beprofitable from social, economic and environmental standpoints.
