Due to human activity, large amounts of organic residue are generated daily. Therefore, an adequate use in agricultural activities requires the characterization of the main properties. The chemical and physical characterization is important when planning the use and management of organic residue. In this study, chemical and physical properties of charcoal, coffee husk, pine-bark, cattle manure, chicken manure, coconut fiber, sewage sludge, peat, and vermiculite were determined. The following properties were analyzed: N-NH4+, N-N0(3)-, and total concentrations of N, P, S, K, Ca, Mg, Mn, Zn, Cu, and B, as well as pH, Electrical Conductivity (EC) and bulk density. Coffee husk, sewage sludge, chicken manure and cattle manure were generally richer in nutrients. The EC values of these residues were also the highest (0.08 - 40.6 dS m-1). Peat and sewage sludge had the highest bulky density. Sodium contents varied from 0 to 4.75 g kg-1, with the highest levels in chicken manure, cattle manure and sewage sludge. Great care must be taken when establishing proportions of organic residues in the production of substrates with coffee husk, cattle or chicken manure or sewage sludge in the calculation of the applied fertilizer quantity in crop fertilization programs.

Glass Membrane

Characterizations of membranes made from cellulose coconut fiber-fiber glass as H<sub>2</sub>O separators in water of electrolyzer has been done. The separators membrane was successfully made with a manual and simple technique, mixing cellulose fiber material produced from the modification of coconut fibers with NaOH immersion process. Cellulose fiber mixed with fiber glass in the composition of 50:0, 40:10, 30:20, 20:30, 10:40, 0:50 (%wt) to get hybrid composite. The results of testing the ability of the membrane as a separator produce H<sub>2</sub> gas concentrations that are more increased than without using a separator. The optimum value produced is 300 ppm in sample 1 which is 50:0:50 %wt, while the H<sub>2</sub> gas production without using a separator which is 51 ppm. For physical properties testing, the addition of mass percent of celluose coconut fiber affects the physical and electrical properties of membrane where the optimum value of % porosity of the material obtained is 73 %, swealling value is 77,5 % and the conductivity value of the material amounting to 1,572 x 10 <sup>-7</sup> S/cm.

The paper presents the laboratory experiments and the results obtained regarding the production and characterization of composite materials with coconut fiber for the manufacture of brake pads for small vehicles and medium performances. The experimental research of composite material with organic components determined the influence of some material factors and parameters of the sintering regime on the physico-mechanical characteristics of the tested samples. Knowledge of these characteristics offers the possibility of pertinent appraisals regarding the behaviour of the composite materials intended for used in brake pads applications. Materials with the best features will be selected to determine the functional characteristics of friction and wear.
