According to the report from the Ministry of Environmental Protection, starting from October 24, 2016, the smog around Beijing-Tianjin-Hebei region has risen again. In response, the Ministry promptly proposed prevention and control recommendations to shift from the past "flooding" emission reduction method to a more precise targeting approach. A certain coal-fired enterprise, to enhance the synchrony of its emergency response, has recently acquired and installed advanced exhaust gas treatment equipment. This equipment allows the waste gas to be filtered before emission, reducing the pollution to the atmospheric environment. It is known that the relationship between the quantity of pollutants $N$ (in mg/L) in the waste gas after filtration and the filtration time $t$ (in hours) is given by $N(t) = N_0e^{-\lambda t}$ (where $N_0$ and $\lambda$ are non-zero constants, and $e$ is the base of the natural logarithm), with $N_0$ being the quantity of pollutants when $t=0$. If after 5 hours of filtration, the quantity of pollutants is $\frac{1}{e}N_0$.
(1) Determine the value of the constant $\lambda$;
(2) Calculate the minimum time required for the amount of pollutants to be reduced to 10% of the initial quantity (accurate to 1 hour).
Reference data: $\ln{3} \approx 1.10$, $\ln{5} \approx 1.61$, $\ln{10} \approx 2.30$.
