	How To Build A Micro Compound Lever Briquette Press North American lumber standard 1.5 inch x 3.5 inch(38 mm x 89 mm) {Has English and Metric Dimensions}, 2 MB, PDF ↓Translated to the following languages↓ Arabic, Bengali, Chinese (Simplified), Chinese (Traditional), Czech, French, German, Hindi, Japanese, Korean, Persian, Polish, Portuguese, Spanish, Swahili, Urdu, Vietnamese This small press works well for single-family use, classroom demonstrations, or a small village. It features a small footprint and easy to build press using hand tools are required. There are two versions, Brace or Notch. Video describing biomass briquette press. Video about building the biomass press by: Ms. Firtle in Greece
	How To Build A Micro Compound Lever Briquette Press using 40mm x 100mm Lumber Here are dimensions for a special metric lumber size of 40 mm x 100 mm for the brace version. 1.3 MB, PDF, Metric Only
	How To Build Biomass Molds {English and Metric Dimensions}, PDF, 6 MB ↓Translated to the following languages↓ Arabic, Bengali, Chinese (Simplified), Chinese (Traditional), Czech, French, German, Hindi, Japanese, Korean, Persian, Polish, Portuguese, Spanish, Swahili, Urdu, Vietnamese This document is about choices. Briquetting for any operation requires a biomass mold of one type or another, whether it is a small village, single family, or classroom operation. You have choices and there are no wrong or right, best or worst, good or bad molds for making biomass briquettes. A variety of molds will work equally well and one type may be best suited for you depending on the availability of construction materials, tools, cost, skill level, and briquetting requirements. This document provides choices to consider when selecting a biomass mold design. Molds for shaping biomass into round, square, sticks, cubes and chunks. Drilled, slotted, and split PVC molds along with slotted wood as an alternate to PVC. Two caulking gun presses, split plunger pistons and more. See Video for Split-Mold testing.

	Caulking Gun Briquette Experiment by: Dr. Zan Smith Good for classroom demonstrations, formulation testing or small production runs. See the updated version for this press in: How To Build Biomass Molds. Caulking Gun Press by Joshua Guinto (See How To Build Biomass Molds for details)
	How To Build A Dry Biomass Grinder/Thrasher 2.5 MB PDF Video describing the Dry Biomass Grinder Thrasher University of Nottingham uses the press and grinder for Kenya project; See https://www.nottingham.ac.uk/etc/news-SIFEKenya.php The grinder was designed to grind a wide variety of dry biomasses, be low-cost and easy to build using mostly hand tools, easy to operate, easy to maintain and require no welding. The grinding process is accomplished by rotating a concrete grinding head with its aggregate exposed against a matching concrete grinding cup with its aggregate exposed, and introducing biomass in between the two surfaces. The grinding cup is supported with two degrees of freedom in order to absorb the movement from an out-of-round grinding head or the accidental introduction of small stones or stick into the grinding space. The grinding head is easily rotated using a hand crank at a slow speed (under 90 rpm). The unit can be powered from a bicycle, a foot powered treadle, a gasoline motor or an electric motor. Grinding pressure is easily adjusted by the weight of a few rocks in a pail. See the Engineering For Change page E4C
	Portable Thrasher-Masher-Chopper By the Legacy Foundation I recommend you consider this new design by Richard Stanley from the Legacy Foundation. Preparing biomass for briquette production remains a crucial step in the briquetting process. Richard has developed (fine tuned and tested in rural Guatemala and Nicaragua over the past three years) a very successful idea as described in his new construction manual. Designing a low cost grinder featuring ease of use, and easy to build, has been a challenge for both of us. We often work closely together in a effort to bring you the best ideas possible. You can contact Richard HERE
	How To Build A Biomass Copper-Cutter 600K PDF Spanish Version Here Video describing the Easy BioChop Wet-Dry Biomass Chopper Cutter See Biomass Chopper by Joshua Guinto Video test cutting prairie grass for a biogas project at the Cincinnati Zoo The chopper/cutter was designed to cut both wet and dry biomass. The chopper is easy to build using mostly hand tools, easy to operate, easy to maintain and requires no welding. The unit runs efficiently at a low crank speed and can be easily operated by women or children. See the Engineering For Change page E4C

	How To Build A Biomass Composer – Rotatable and Portable 2.6 MB, PDF Spanish Version Using either a plastic or steel drum you can easily fabricate a barrel composter for the aeration of biomass that is both rotatable and portable.
	How To Build A Large Compound-Lever Biomass Briquette Press 340K, PDF This is the traditional large compound lever press used all over the world, and works with molds diameters from 3 inch to 6 inch. Mold designs have greatly improved since the original design of this press and we suggest downloading the How To Build Biomass Molds. See the compendium for a variety of biomass mold suggestions.
	How To Build A Small Single-Lever Square Biomass Briquette Press 570K, PDF If PVC is not available or expensive in your area then the 3 inch square wood mold could be an alternate. Mold designs have greatly improved since the original design of this press and we suggest downloading: How To Build Biomass Molds for a variety of biomass mold suggestions. We now have a better method for making a square briquette using a wood mold.
	How To Build A Small Biomass Briquette Press English, 880K, PDF How To Build A Small Biomass Briquette Press French, 600K, PDF Suggested for use as a classroom demonstration briquetting press or where construction resources are limited Mold designs have greatly improved since the original design of this press and we suggest downloading: How To Build Biomass Molds. See the compendium for a variety of biomass mold suggestions.
	How To Build A Large Single-Lever Biomass Briquette Press English, 400K, PDF If the large compound lever press is inappropriate for your needs then a large single lever press might work in your area. Includes removal jig. Mold designs have greatly improved since the original design of this press and we suggest downloading: How To Build Biomass Molds. See the compendium for a variety of biomass mold suggestions.
Briquetting Video by The Legacy Foundation Briquette Ratchet Press by The Legacy Foundation	If you have not read the briquetting instructions available at the Legacy foundation, I highly recommend reading them thoroughly prior to starting a briquetting operation. They also have several biomass briquette presses made from metal. See them HERE The Legacy Foundation provides training, technology and media services for biomass fuel briquette production, environmental conservation and income generation throughout the world. They have a number of excellent manuals on briquetting. Visit them HERE
