A insustentabilidade dos produtos importados para a economia da Nig�ria, bem como a necessidade de gest�o ambiental de res�duos, exigem mais investimento em mat�rias-primas de origem local e res�duos recicl�veis biodegrad�veis como substitutos de mat�rias-primas na produ��o de ferramentas para uso industrial e dom�stico. Este trabalho procura abordar a reciclagem de res�duos agr�colas para a produ��o de ferramentas utilizadas em processos de usinagem abrasiva. Foi realizada uma an�lise comparativa de material abrasivo feito a partir de dois materiais de origem local, pervinca e cascas de palmiste, para investigar a sua substitui��o por abrasivos importados usados na produ��o de lixa/papel de lixa. Foram desenvolvidos comp�sitos de cascas trituradas com liga��o de resina de poli�ster usando compress�o de molde e lixa/papel de lixa foram produzidos usando o m�todo de pulveriza��o manual. As conclus�es do trabalho e as suas contribui��es para o conhecimento devem ser especialmente �teis para estudantes de ci�ncia e engenharia de materiais, tecnologia de fabrico, profissionais na �rea de comp�sitos e tecnologia de fabrico, Minist�rio Federal da Ci�ncia e Tecnologia da Nig�ria e desenvolvedores de novos materiais.
