Let’s go green with sustainable solutions

Sustainable solutions towards the environment come under various classes and categories. They include food, water, building, clothing, energy, community, transport, business, economy and ecosystem.

Community Supported Agriculture consists of a community of individuals who pledge support to a farm operation so that the farmland becomes, either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits of food production. Typically, members of the farm pledge in advance to cover the anticipated costs of the farm operation and farmer's salary. In return, they receive shares in the farm's bounty throughout the growing season, as well as satisfaction gained from reconnecting to the land and participating directly in food production. Members also share in the risks of farming, including poor harvests due to unfavorable weather or pests. By direct sales to community members, who have provided the farmer with working capital in advance, growers receive better prices for their crops, gain some financial security, and are relieved of much of the burden of marketing.

Also, sustainable solutions include greywater recycling which is obtained through waste water generated from domestic activities such as laundry, dishwashing, and bathing which can be recycled on-site for uses such as landscape irrigation and constructed wetlands. Greywater differs from water from the toilets which is designated sewage or blackwater to indicate it contains human waste. Greywater composes 50–80 percent of residential waste water generated from all of the house's sanitation equipment (except toilets).

Bio-fuel are also form of sustainable solutions for the environment where are wide range of fuels are derived from biomass. The term covers solid biomass, liquid fuels and various biogases. Bio-fuels are gaining increased public and scientific attention, driven by factors such as oil price hikes and the need for increased energy security.

Bioethanol is an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops. With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feed stocks for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions. Bio-ethanol is widely used in the USA and in Brazil.

Bio-fuels provided 1.8 percent of the world's transport fuel in 2008. Investment into bio-fuels production capacity exceeded $4 billion worldwide in 2007 and is growing.
