The waste-product theory of aging: Simulation of metabolic waste production
Experimental Gerontology, 1991A mathematical model of cellular metabolism is used to relate the rates of cell division and waste production to the concentrations of oxygen and glucose in the medium in which a normal diploid cell culture is grown. The metabolic model in tandem with an earlier waste-content model based on the waste-product theory of aging provides a unified cell ...

Production of Polyhydroxyalkanoates from Fatty Wastes [PDF]
Journal of Polymers and the Environment, 2012 The production of polyesters from triglyceride containing substrates was investigated. A first filter step based on lipase activity was followed and those bacteria potentially able to degrade oils or animal fats were further tested for their polymer accumulation properties, selected and kept for further studies. In a second step, bacteria were directly

Water Environment Research, 1992
This paper provides a review of literature published in 1995 on the subject of power production waste. Topics covered include: fossil-fueled plants (coal combustion waste product characterization, coal combustion waste product utilization, and coal combustion waste product disposal); and nuclear power plants (low-level wastes and high-level wastes). 46

Waste, Product and By-product in EU Waste Law
elni Review, 2007The European Parliament voted to include a “by-product” definition in the Waste Framework Directive. A few days later, the Commission came up with an “Interpretative Communication”. The purpose of this article is to find a way of exploring the “new” definition of by-products in order to find more utility than disturbance.

SSRN Electronic Journal, 2011
This paper studies how a firm can create and capture value by converting a waste stream into a useful and saleable by-product (i.e., implementing by-product synergy (BPS)). We show that BPS creates an operational synergy between two products that are jointly produced.

Hide and tanning waste by-products
1994During the production of leather several waste by-products are produced which may cause pollution unless they are used as a feedstuff. The yearly world production of fresh hides (cattle, buffalo, sheep and goat) is estimated to be 8–9 million tonnes per year (FAO, 1990).

Waste Production in Aquaculture
2022Due to rivalry resulting from the exploitation of natural resources such as soil and water by other production and development businesses, strengthening aquaculture has emerged as an alternative to boosting aquatic production. However, enhanced waste disposal from aquaculture production systems is required for resilience, as is extra inclusion, such as

Waste, Ownership and Bodily Products
Health Care Analysis, 2000This paper considers the extent to which bodily parts and products can be legitimately regarded as "waste" in law and what are the legal consequences of regarding them in this manner. First, what is the approach of English law to bodily parts as property? Secondly, why is this an important legal issue?
