1. Crescimento e teor de cromo em mamoneira cultivada em solo receptor de resíduos de curtume e carboníferos
RESUMO A produção de resíduos tem aumentado em proporção direta com a industrialização dos países. Sendo assim, a disposição adequada desses resíduos é uma questão largamente discutida entre os órgãos ambientais. Por isso, o objetivo deste trabalho foi estudar o efeito residual de adições sucessivas de resíduos de curtume e da mineração d

2. Characterization of a novel lipase from Bacillus sp. isolated from tannery wastes
Kinetics of a lipase isolated from Bacillus sp. was studied. The enzyme showed maximum activity at pH 9 and temperature 60ºC. The Michaelis constant (K M 0.31 µM) obtained from three different plots i.e., Lineweaver-Burk, Hanes-Wolf and Hofstee, was found to be lower than already reported lipases that confirmed higher affinity of the enzyme for its substra

3. Incorporation of solid wastes in red ceramics: an updated review
A review on the fundamentals and technological advances in the incorporation of industrial solid wastes into red ceramics was updated since 1997, when the first overview on this subject was published by Dondi, Marsigli and Fabbri. Other works conducted before this period, but not covered by that overview were also reviewed. Modifications were introduced in t

4. Study of influence of the shave leather chemically treated addition on the characteristics of mortar cement Portland / Estudo da influência da adição de serragem de couro tratada quimicamente nas características de argamassas de cimento Portland
The purpose of this study was to examine the major environmental concern for the large volume of toxic wastes generated by industries of tanneries and the search for a technological solution for the treatment of this waste. The attempt to tie the chromium ion present on residue, shave chrome leather, was used in three steps. In the first step, solutions were

5. Modelagem e simulação de um gaseificador em leito fixo para o tratamento térmico de resíduos sólidos da indústria calçadista
A indústria calçadista gera uma significativa quantidade de resíduos, sendo uma alternativa para destino destes o tratamento térmico, que reduz o volume e estabiliza componentes perigosos. Por conseguinte, isto vai ao encontro dos novos desafios na busca de fontes de energias alternativas pelo fato da combustão destes resíduos ser bastante convidativa

6. Chromium(VI)-resistant yeast isolated from a sewage treatment plant receiving tannery wastes.
A Cr(VI)-resistant yeast, designated strain DBVPG 6502, was isolated from a sewage treatment plant receiving wastes from tannery industries in Italy. The strain was tentatively identified as a species of Candida based on morphological and physiological analyses. This strain was highly resistant to Cr(VI) when compared with eight other yeast species, growing
