Human excreta, fecal sludge and wastewater are often referred to as wastes (see also human waste). Within the concept of a circular economy in sanitation, an alternative term that is being used is "resource flows". [4]: 10 The final outputs from the sanitation treatment systems can be called "reuse products" or "other outputs".
[11] [12] The ability of living organisms to harvest solar energy and achieve quantum efficiency near unity [12] is due to the culmination of ~3.5 billion years of evolution. [13] This efficiency is achieved in plants with a series of energy transfer steps, that are carried out through pigment-protein complexes (e.g. Photosystem II). [11]
Solar reforming is the sunlight-driven transformation of waste substrates to valuable products (such as sustainable fuels and chemicals) as defined by scientists Subhajit Bhattacharjee, Stuart Linley and Erwin Reisner in their 2024 Nature Reviews Chemistry article where they conceptualized and formalized the field by introducing its concepts, classification, configurations and metrics.

Biological photovoltaic devices are a type of biological electrochemical system, or microbial fuel cell, and are sometimes also called photo-microbial fuel cells or “living solar cells”. [3] In a biological photovoltaic system , electrons generated by photolysis of water are transferred to an anode . [ 4 ]
The potential solar energy that could be used by humans differs from the amount of solar energy present near the surface of the planet because factors such as geography, time variation, cloud cover, and the land available to humans limit the amount of solar energy that we can acquire.
Various projections of future energy use identify solar PV as one of the main sources of energy generation in a sustainable mix. [64] [65] Most components of solar panels can be easily recycled, but this is not always done in the absence of regulation. [66] Panels typically contain heavy metals, so they pose environmental risks if put in ...
The following outline is provided as an overview of and topical guide to solar energy: Solar energy is radiant light and heat from the Sun. It has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar ...
In actuality, however, plants do not absorb all incoming sunlight (due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels) and do not convert all harvested energy into biomass, which results in a maximum overall photosynthetic efficiency of 3 to 6% of total solar radiation.
