In principle, you can distil the diesel and capture the methane gaseous fraction to heat the next batch. The real challenge is the variable inputs has a huge impact on the diesel recovery - which is why you need some scale to smooth out the variances. On a small scale its often not economical. But farmers do this all the time. https://en.wikipedia.org/wiki/Pyrolysis https://en.wikipedia.org/wiki/Pyrolysis
