I'm not the expert on this stuff, but, the main reason people want to stay away from pine is the pitch. You can use it, but you have to run a sacrificial batch of biodiesel through it to remove the pine resins. Once it's passing through the sawdust clean, water wash what went through and supposedly the pine resins will wash out.

Try it and let us know how it works out for you.

I know I keep repeating myself here but I made up a column of kiln dried fir planer shavings year before last and they worked wonderfully. I used them after a running the bio through a couple static water washes (to remove the methanol). The shavings removed the vast majority of the water and soap. I never observed anything visible in the fuel or residue that led me to believe there was any resin present.
I use what ever shavings the carpentry shop next door gives me now. It's all kiln dried and I haven't seen anything odd yet other than spectacular soap removal.

I would say go ahead and use the pine if it's good and dry and please report the results back here.
As I see it, the determination of what woods work best is still up in the air. At this time I'm of the thought that the coursness and dryness of the shavings are quite important. What other factors are equally important and in what order? I don't know.

I'm with DoubleD. I use pine shavings designed to be used as animal litter. after reading all the stuff about resin I experimented and left some of the stuff in a jar with bio and another in methanol. With the bio nothing was visible after a week. I evaporated the methanol and got the tiniest bit of residue.

I get resin with the first batch. The pine planer shavings that I use come from the sawmill, so the wood is still green (anything fresher will still be growing Smile). When I collect the shavings, the resin smell is so strong that it burns my eyes. I need to wind dry the shavings before I use it, but it works well and removes all the soap. Done many batches (250litre finished bio per batch) through a 45gal pine wood shaving drum and still works.
