Dear All,
We all know well about the waste valorization issue.
For Wet waste ( organic Part) most turns primarily for energy recovery or material recovery, Also few chooses for byproducts like ethanol, organic acids etc.
Ideally we think the raw material is available at source and we plan/think for a process at ideal location like in Lab.
But In Practical, to turn the waste to resource lot of dimensions need to play at a time, which is a major constraint in ref subject.
If we could process a step up material from raw waste in decentralized manner, like partially stabilized/dried/degraded/fermented or any way, and collecting /processing it centrally for mass production, where all dimensions may be available. i.e in decentralized way we will produce a building blocks and at central facility we could convert it for various finish goods/energies.
Means A partially stabilized/processed material from wet waste will be called a building block in production for various waste to resource option.
I am Thinking in this way for my PhD Research.
Is there any work happen in this way, or any one working in this thread.
Please, It will help me to build my problem statement, Rather its a practical problem in today's scenario, as enough fundamental technological research are available, for every path and process, but integration of the different techniques, in available resources is the key issues, and need of the hour.
Applying above thought one should be able to process a stable raw material with minimum transportation cost from 1000 decentralized sources to a single centralized finish good processing unit/plant

Dinesh joshi.
Thanks Sir,
But i mean "NOT A CONSTRUCTION MATERIAL"
Building block mean a unit raw material, based on same lot of other process could be done, in waste utilization.
Dinesh.
I am taking your question to mean, quite literally, turning the liquid waste into solid bricks, for easier storage, shipping, etc. I would think that some method for putting into molds and drying or baking could be done, though you may lose potential energy in the process. I also think the dried "building block" could have a use as a solid fuel for certain purposes. I hope this information is useful in your research.
Dear Dinesh ,
If you want to utilise waste materials for making construction blocks / bricks, it is necessary to classify waste material as per their properties and then one can check their suitability considering available process of manufacture. Normally construction blocks made from organic wastes are less in strength and stiffness and less durable.
Your interest looks in utilization of wet waste in useful product. fFor better waste management and in order to develop green and clean environment technology, You can have following some options on which
a lot of work can be done.
1.Converting waste organic waste into suitable bi product useful for agriculture / fuel pallets etc
2. Inorganic wastes into useful low energy products for non structural applications, decorative articles,
3. Use of plastic waste into suitable binder or recycled materials.
4 use of hard and comparatively durable materials for suitable applications like furniture, light weight blocks, low cost wall panels etc
Since waste materials generated may contain different materials of varying nature and quality. Hence it is necessary to have separation process plants which can decentralized. Then process plant can be designed and placed at suitable locations to reduce transportation cost.
Based on the data available, one can define the work area and scope of the work which will help to define objectives for the research work .
I hope you got it.
