\textbf{Abstract}
\begin{abstract}
\normalsize{
Cassava (\textit{Manihot esculenta}) is widely grown in the tropical countries for its starchy root. Cassava is an important source of calories for human and is often cultivated for starch production, which is a high value commodity for various industries such as brewing, paper, adhesives, plastics and chemicals. Cassava peel generated from the starch manufacturing industries is of great concern to the environment due to cyanogenic glucosides contents. However, this huge amount of biomass can be converted to biochar, bio"=oil and pyrolysis gas by low"=cost slow pyrolysis, which can be a source of extra income to the farmers. In the present study, a laboratory"=scale top"=lit up"=draft pyrolysis (TLUD-Pyro) reactor was used for the slow pyrolysis of dried cassava peel from Tanzania. The pyrolysis chamber was filled with 500g chopped cassava peel ($<$\mbox{1\,cm} particle size) and sealed with a heat resistant silicone. Woodchip was used as a fuel for the gasifier (TLUD). The gaseous products coming out of the pyrolysis chamber were condensed at 0 °C while the non"=condensable pyrolysis gas was combusted by using a burner. Temperature was continuously monitored and reached to a maximum level 985, 704, and 444 °C for gasifier, combustion zone (After"=burner) and the pyrolysis chamber, respectively. When the pyrolysis temperature reached above 100 °C, the pyrolysis gas was combustible for about 30 min. During the slow pyrolysis of cassava peel an average yield of biochar, condensate, and pyrolysis gas were found to be \mbox{36\,\%}, \mbox{25\,\%}, and \mbox{39\,\%}, respectively. The bio"=oil can be extracted from the condensate. Cassava peel was found to be a good feedstock for the TLUD-Pyro reactor in order to produce biochar, bio"=oil and pyrolysis gas. A detailed characterisation of the biochar and the condensate is required in order to exploit their utilisation.}
