we need to use different algae for the municipal solid waste bio remediation this we need to know that is it efficient to use algae for solid wast bio remediation.
Algae are primary producers that utilize sunlight and elemental minerals to create carbohydrates and oxygen. When solid waste is landfilled, rain and the liquids released from decomposition amass in what is known as landfill leachate. This liquid waste has many solubilized elements within it. Algae can utilize the dissolved elements to synthesize cell biomass. As algae grow, they also degrade organic pollutants within the landfill leachate, through direct metabolism and the cellular production of oxygen during photosynthesis
Macroalgae have long been used for the remediation and adsorption of the contaminants. Having the advantages of low cost raw material, big adsorbing capacity, no secondary pollution, etc., algae may be used to treat industrial water containing heavy metals (see review Roy et al. 1993. Journal of Environmental Science & Health Part A, 28(1), 37-50)

Dear AM, This indeed is a bold and a practical concept for bio-remediation of the trouble-some landfills, existing in all Metros. Algae have the capability to absorb contaminants and nutrients. Only we have to be careful to provide free space around each sets of algae-pods, If they are placed too near, then the situation of anerobic nature would form as the landfills release a lot of CH4, Algae by themselves absorb cell bio-mass and utilise micro-elements. Output- Algae produce if they are used for food production, it is required to be tested before human consumption. At best if they are deep oil-fried, it takes care of most harm causing elements... well wishes..
I agree with Drs.Seshadri, Mganga, Islam and Billah: it depends on which wastes biodegradation phase is being targeted for remediation. As essentially wet organisms, selection, culturation and maintenance of the best algae grouping for the bioremediative design will have to be for a wet, oxic, environment. Management of the liquid phase of landfilled wastes biodegradation might be more effective. In an open setting algae maintenance would favor open channels in the wastes with attached (benthic) algae, natural light suffusion, and drainage or circulation, as well as algae harvesting to avoid blockage or anaerobic conditions in algae 'ponds', and design to reduce site nuisance effects.Downgrade of the landfill the nitrogen, phosphorous and and trace toxic substances have to be at levels not injurious to quality in shallow groundwaters or surface waters.. Landfills naturally have both aerobic and anaerobic fractions, so this aspect and pH of the liquid phase entering algae 'ponds' must be satisfactory. Algae can be harvested and used for N and P properties or according to purpose. So remediation using algae can be a solution once setting and end products are designed to maximize the benefits,
