1. Insect Problems
Insect Problems: Insect problems may occur mainly waste are not decomposing timely due to so many reasons. The reasons might be high moisture content of composting materials or inoculums are not used or good inoculums are not used or not well mixed up or bins are placed in dark and damply /moist location, or no good air circulation or wastes are not cut into pieces. Sometimes season itself favors the breeding of insects so insect problems arises.
Solutions: First of all, all the necessary guidelines or technique has to use for decompositions of waste materials as waste should be cut into pieces, bin should be placed in open (good air circulation area), waste materials should not be too moist, good inoculums has to be used, brown (dry matters) and fresh (green matters) matters should be in good proportion. Wet or moist waste materials are the main reasons for insect problems. Put withered waste (partially dry) materials in bin and use compost or Bokasi in waste materials for quicker decomposition.
2. Leachate Problems
Leachate Problems: This problem is faced when wet or too moist waste materials are used for composting otherwise, bins are placed in damply area, dark area or there is no good air circulation.
Solutions: Bins should be placed in open or good air circulated area. Too moist waste materials should not be used or if the fresh wastes or moist wastes have to be used, it could be wither (air dry) for a while (few hours) and put into the bins. Attention should be given for proportion of dry and green matter. Leachate problem is created if only green or fresh matters are used for composting.
3. Good Inoculums
Good Inoculums: Inoculums has to be used for faster decomposition of wastes. There may be questions of good inoculums. Bin users are using various inoculums (EM, compost, bokasi, surface soil) and some time ash as inoculums.
Solution: Compost, EM and Bokasi are the good inoculums but ash cannot take as inoculums. Soil (surface soil) can be taken as inoculums but it is not as good as compost, EM and bokasi.
4. Brown (Dry) Matter:
What is Dry Matter?: Any organic dry waste can be used as dry matter and can be used for composting which will be good source of Carbon for microorganisms. Leachate problems might occur when no dry matters are used for composting.
Use of Dry Matters: All the organic dry wastes are dry matter. Waste papers, dry matters of farm wastes, rice husks, wood dusts etc are dry matters. At least, dry and fresh waste should be in 1:1 ratio (one part dry and one part green) proportion. That will help to increase organic content of compost and leachate problem will be minimized.
5. Compost Quality
How will be Compost Quality: It is first experience, no information available about quality of home compost (Home Compost Bin). But it is expected that quality should be better and should contain higher rates of nutrients. The composting materials used in home composting all are purely organic wastes no inorganic wastes are mixed up.
Compost Quality: As indicated by compost analysis, the nutrient contents (Nitrogen, Phosphorus and Potassium) is better than other compost reported by different agencies and organic matter is in average range. Organic matter content of compost can be increased by increasing proportion of dry matter for composting. The pH of compost is also in safer side
