Disclosed are a circuit-board powder made eco-friendly panel free from aldehyde and carbon emission and the production method thereof. The raw materials of the panel include circuit-board powder, isocyanate, mold-releasing agent, water, wood fiber powder and carbon fiber. The panel is obtained by mixing said raw materials and pressing the mixture. The content of circuit-board powder can be as much as over 95% by mass. The obtained panel has no bubble defects and good water resistance. La présente invention se rapporte à un panneau écologique constitué de poudre de déchets de cartes de circuit imprimé dépourvu d'émissions d'aldéhyde et de carbone et à son procédé de production. Les matières premières du panneau comprennent de la poudre de déchets de cartes de circuit imprimé, de l'isocyanate, un agent de démoulage, de l'eau, de la poudre de fibres de bois et de la fibre de carbone. Le panneau est obtenu par le mélange desdites matières premières et par le pressage du mélange. La teneur en poudre de déchets de
