I know it’s still composting but you could get a little tabletop wormery for work - would save you taking them home. Of course you’d still have to get the compost home if you didn’t use ti for repotting plants in the office..

don’t throw them in the compost!! you can put them straight on the garden instead!! spread them around plants, a couple of cms thick, and they eep down weeds and fertilise the soil at the same time. cracking!!

I read somewhere that ants don’t like coffee so won’t cross lines of coffee grouns so you can use them for keeping ants at bay.

you can use coffee as a stain for wood. just stew the old coffee grouns in water for a good wile, a couple of hours at least then you can use the juice to stain wood around the house. i have so me mahogny stained chairs and it’s great for touching up scratces and is a lot easier to handle and smells a lot better than normal wood stain.

Hi,

These can be commericaly collected. The spect coffee has following chemical properties

Spent Coffee Waste
Parameter Value
Carbon 33.6 %
Hydrogen 4.2 %
Nitrogen 1.14 %
Sulfur 0.03 %
Moisture 40 %
Ash 0.66 %
Oxygen 20.37 %
GCV 3500 K Cal/kg
Bulk Density 640 kg/m3 @60% Moisture.

Since the carbon content is high as 33.6% then these can be dried to 30% moisture content & then can be turned into the powder. Once it turn into the dry powder you can put a binder & compress them to the shape of stones. These can be used to feed in the boiler to genrate steam or hot water which can be further used for the comfort or process heating.

Hi, is there any company out there that would like to buy spent coffee ground? I have source of the material. Hear from you soon.

Hi Dean.

What sort of volume do you have?

Hello:

Can you tell me more about spent coffee grounds? We need about 10 - 20 ton delivered to Boston, MA.

Can you help?

We have spent coffee grounds in Mexico 10 ton every day

I am interested in knowing how you go about colecting the spent coffee ground product. Could you please give me a litttle information regarding this. Thank you

I recently started recycling the coffee grounds and filters from work (PA DEP), where my co-workers generate abut two pounds of coffee grounds per week. Like SaraR, I take the grounds home on the bus and get strange looks from the other passengers, but no complaints. Currently, the grounds get composted with horse manure donated by my neighbors, but in the future I am contemplating using my spreader to directly apply the dried grounds to my lawn. The coffee grounds are about the same size as commercial fertilizer and just as beneficial. This Fall, I intend to begin collecting coffee grounds from other floors and to start a worm composting bin under my desk using lunch scraps for food and shredded office paper or newspapaper for bedding.

You can scrub your face with coffee grounds. it works ;)

What would be the best way of drying large quantites (30-100lbs) of wet coffee grounds so they don’t mold till you use them?

I am currently working on using coffee grounds as fuel. I have been agglomerizing
the grounds to produce small ball shaped pellets that when dried provide an excellent fuel for my pellet burning stove. The problem is the binder … and the ratios … what works best is wheat flour in a 10 to 1 ratio , coffee grounds to flour. Agglomerize, let sit in a warm place for 48 hrs. and burn….they burn at about 10,500. btu / lb white flame ,not smell and everything else is good

Have you thought of using shredded paper as a binder? You can buy a log maker (it squeezes the paper to make logs) off the Internet. Mix the paper with your coffee and hay presto perfect logs.
