Much sawdust is treated as waste and deposited in landfills; with time, the city landfills have to be made larger and larger and/or deeper and deeper. We have created composites on the basis of dry sawdust and only 3 wt% to 15 wt% of phenylethoxysiloxane binders of two kinds under pressures up to 15 MPa and temperatures up to 220°C. Hot pressing of one of the composites containing 3 wt% of one of the polymeric binders at 110°C provides the impact viscosity = 12 kJ/m2 while the pressing at 200°C results in the value of that viscosity = 30 kJ/m2. Another option is using 5 wt% of the same polymer at 110°C what gives the impact viscosity = 20 kJ/m2. Water absorption after 24 hours exposition in water for 15 wt% of the same polymer amounts to 55.5 wt% when the composite is prepared at 130°C but only 2.9% for the composite made at 170°C. Given low‐to‐negligible prices of sawdust, composites with useful properties and low prices can be made from it—along with mitigation of waste creation.
