德国采购需求：B2B采购解决方案、企业采购解决方案、商业供应链解决方案、B2B采购解决方案、企业采购解决方案、专业供应商解决方案

I'm interested in your food waste composting machine and would like more info. Specifically, I'd like to know about the pricing, availability of spare parts, maintenance requirements, and warranty options. Additionally, could you explain how user-friendly the machine is? We process about 5,760 tonnes of organic waste annually. Can we sell the resulting discharge liquid? If so, what are its applications? Lastly, since we're located in Germany, do you have any local suppliers or distributors? Looking forward to your detailed response!
